Abstract
Description
[Technical field]
[0001] This application claims priority to U.S. Application No. 63 / 271,826, filed October 26, 2021, which is incorporated by reference in its entirety. The present disclosure provides an invention for generating laboratory water and dispensing laboratory water at different temperatures, typically room temperature and above room temperature, for various purposes in laboratories and biological / pharmaceutical production facilities. [Background technology]
[0002] Modern laboratories and biological / pharmaceutical production facilities require a reliable source of purified water for a variety of purposes. Purposes include cleaning glassware and fermentation tanks, generating aqueous solutions, performing analyses, preparing growth media for cells, and use in autoclaves for sterilization of materials. Often, certain operations require the water to be above room temperature, such as in solubilizing cell growth media for cell propagation.
[0003] In addition to water purity, precise temperature control of water is often required for various applications. While many applications may utilize water at chilled to ambient temperatures (e.g., about 60°F to about 80°F) depending on the season and location of the laboratory and biological / pharmaceutical production facility, some applications may require warmer water at a precise temperature. Furthermore, due to the time-dependent nature of various processes, it is desirable to have precisely heated water instantly available.
[0004] Typically, the production of highly purified water is expensive, time-consuming, and energy-intensive due to the equipment, consumables, and precision required. Thus, there is value in reducing the waste of purified water. However, efficient use of water is often difficult to balance with the emphasis on immediate availability. Traditionally, water at ambient temperature may be drawn into a container and heated separately. However, this process requires additional time and is unlikely to accurately heat the water to a specified temperature without additional monitoring. Furthermore, such processes generally result in waste, since laboratory water removed from a distribution system cannot easily be returned to the distribution system without the risk of contamination.
[0005] It would therefore be advantageous to have a water distribution system that could provide water at both ambient and set point temperatures on demand while minimizing waste. It would be further advantageous if the water distribution system provided careful monitoring of the water to provide the precise conditions required for complex applications.

[0055] The present invention is also suitable for the production of other molecules, including fusion proteins. Preferred fusion proteins include receptor-Fc fusion proteins, such as certain trap proteins. The protein of interest can be a recombinant protein (e.g., an Fc fusion protein) that contains an Fc portion and another domain. In some embodiments, the Fc fusion protein is a receptor-Fc fusion protein, which contains one or more extracellular domains of a receptor linked to an Fc portion. In some embodiments, the Fc portion contains a hinge region followed by the CH2 and CH3 domains of IgG. In some embodiments, the receptor-Fc fusion protein contains two or more different receptor chains that bind either a single ligand or multiple ligands. For example, the Fc fusion protein is a trap protein, such as an IL-1 trap (e.g., rilonacept, which contains the IL-1RAcP ligand binding domain fused to the Il-1R1 extracellular domain fused to the Fc of hIgG1, see U.S. Patent No. 6,927,044), or a VEGF trap (e.g., aflibercept or ziv-aflibercept, which contains the Ig domain 2 of the VEGF receptor Flt1 fused to the Ig domain 3 of the VEGF receptor Flk1 fused to the Fc of hIgG1, see U.S. Patent Nos. 7,087,411 and 7,279,159). In other embodiments, the Fc fusion protein is a ScFv-Fc fusion protein, which contains one or more of one or more antigen binding domains, such as a variable heavy chain fragment and a variable light chain fragment of an antibody bound to an Fc portion. Derivatives, components, domains, chains, and fragments of the above are also included.
[0056] Other proteins lacking the Fc portion may also be produced according to the present invention, such as recombinantly produced enzymes and mini-traps, which are trap proteins that use a multimerization component (MC) instead of the Fc portion and are disclosed in U.S. Patent Nos. 7,279,159 and 7,087,411. Derivatives, components, domains, chains, and fragments of the above are also included.
[0057] The present invention is also applicable to the manufacture of biosimilar drugs. Biosimilar drugs, often referred to as follow-on products, are defined in various ways depending on the jurisdiction, but usually share common characteristics compared to a previously approved biological product in that jurisdiction, called the "reference product." According to the World Health Organization (WHO), a biosimilar drug product ("biosimilar") is a biotherapeutic product that is similar in quality, safety, and efficacy to an already approved reference biotherapeutic product and is currently used in many countries, such as the Philippines.
[0058] Biosimilars in the United States are currently described as: (A) a biological product that is highly similar to the reference product, despite minor differences in clinically inactive ingredients, and (B) there are no clinically meaningful differences between the biological product and the reference product in terms of product safety, purity, and efficacy. In the United States, biosimilars are indicated, interchangeable biosimilars or products that may be substituted for the previous product without the intervention of the healthcare professional who prescribed the previous product. In the European Union, biosimilars are currently biological medicines that are highly similar to another biological medicine (called a "reference medicine") already approved in the EU in terms of structure, biological activity and efficacy, safety, and immunogenicity profile (the inherent ability of proteins and other biological medicines to trigger an immune response), and Russia follows these guidelines. In China, biosimilars currently refer to biological medicines that contain the same active substances as the original biological drug, are similar to the original biological drug in terms of quality, safety, and efficacy, and have no clinically meaningful differences. In Japan, biosimilars are currently products that are bioequivalent / quality equivalent to the reference product already approved in Japan, in terms of quality, safety, and efficacy. In India, biosimilars are currently referred to as "similar biological products", where a similar biological product is one that is similar in terms of quality, safety, and efficacy to an approved reference biological product on the basis of comparability. In Australia, biosimilar medicines are currently very similar versions of a reference biological product. In Mexico, Colombia, and Brazil, biosimilars are currently biotherapeutic products that are similar in terms of quality, safety, and efficacy to an already approved reference product. In Argentina, biosimilars are currently derived from an original product (comparator) that has common characteristics. In Singapore, biosimilars are currently biotherapeutic products that are similar in terms of physicochemical properties, biological activity, safety, and efficacy to an existing biological product registered in Singapore. In Malaysia, biosimilars are currently new biological medicines developed to be similar in terms of quality, safety, and efficacy to an established drug that is already registered.In Canada, a biosimilar is a biological drug that is highly similar to a biological drug already approved for marketing. In South Africa, a biosimilar is a biological drug developed to be similar to a biological drug already approved for human use. Biosimilars under these and any revised definitions and their synonyms are within the scope of this invention.
[0059] The present invention may also be employed in the production of recombinantly produced proteins, such as viral proteins (e.g., adenovirus and adeno-associated virus (AAV) proteins), bacterial proteins, and eukaryotic proteins. Additionally, the present invention may be employed in the production of viruses and viral vectors, such as parvoviruses, dependoviruses, lentiviruses, herpesviruses, adenoviruses, AAV, and poxviruses. EXAMPLES
[0060] The following examples illustrate operating parameters of embodiments in accordance with the present invention and are not intended to limit the scope of the invention in any way.
[0061] The Laboratory Water Generation and Distribution System can continuously and consistently generate water for laboratory and production applications and cleaning. The system's functions can be controlled through a PLC. Typically, point-of-use (POU) valves are manually or pneumatically operated. Automated POU valves with PLC can be used for autoclaves and glasswashers and can communicate with the PLC of the RODI loop. The PLC has connectivity to enable new control systems and can prevent out-of-spec water from being dispensed.
[0062] The loop may operate in a recirculation mode with lab water at approximately 68°F. The temperature may utilize a PID control loop to ensure the lab water is at a selected temperature. If the temperature exceeds a selected temperature [e.g., 77°F], an alert may be turned off. Additionally, the lab water in the main loop may be monitored for conductivity [e.g., <1.0 μS / cm] and total organic carbon (TOC) [e.g., <50 ppb]. For example, an alert value at 80% of ASTM Type II quality requirements may be turned off when the RODI exceeds a pre-set conductivity or TOC.
[0063] Dispense pressure can be controlled by a back pressure control valve on a PID loop with a return line pressure transmitter that can control pressure and provide an alert if the loop pressure exceeds or drops below a preset pressure.
[0064] It should be understood that biopharmaceutical production processes, in particular, require a high degree of specificity in preparing materials. Various production processes can be highly dependent on the temperature of the water and other materials utilized, and the processes can also be time-dependent. Thus, while conventional practice may involve drawing water from a common source and heating or cooling as needed, typical equipment may not be equipped with sensors and / or feedback systems to allow for fine control of temperature in the manner required. Furthermore, time-dependent production processes involving several steps may not tolerate the delays associated with conventional methods of preparing temperature-specific laboratory water. Thus, the systems disclosed herein advantageously eliminate the problems of conventional systems and methods by providing an accurate temperature-controlled water source that can be pre-set, maintained, and made available on demand. Furthermore, unused temperature-controlled water is cooled and recycled such that waste of water purified by the systems and methods herein is minimized.
[0065] Laboratory Water Distribution Loop System 100 1A-1C, an exemplary laboratory water distribution loop system according to an embodiment is depicted. As shown in FIG. 1A, the laboratory water distribution loop system 100 includes a laboratory water production skid 105, a storage tank 110 in fluid communication with the laboratory water production skid 105, a main distribution loop 115 in fluid communication with the storage tank 110, and a secondary distribution loop 120 extending from the main distribution loop 115 and in fluid communication with the main distribution loop 115 in a chase-the-tail configuration, where the secondary distribution loop 120 returns to the main distribution loop 115 or, alternatively, returns directly to the storage tank. The system further includes one or more outlets 125, each outlet 125 connected to one of the main distribution loop 115 and the secondary distribution loop 120 for discharging water from one of the distribution loops. The main distribution loop 115 and the secondary distribution loop 120 may be selectively connected by one or more valves 130 (e.g., 130A). In some embodiments, the main distribution loop 115 includes a heat exchanger or chiller 135 configured to maintain the lab water at a baseline temperature. In some embodiments, the secondary distribution loop 120 includes a heat exchanger 150 configured to raise the temperature of the lab water received from the main distribution loop 115 to a set point temperature and maintain the water at the set point temperature. The system 100 further includes one or more interface units, or operator interface terminals (OITs) 165, for a user or operator to interface with the system 100, including to receive information and / or provide input for control of the system.
[0066] Water Generation Skid The water generation skid 105 may include a water source for receiving potable water or other water that may be treated into laboratory water. Various processing steps may be used to generate laboratory water that preferably meets ASTM Type II standards. For example, potable water may be filtered by various media, softened, dechlorinated, deionized, distilled, and / or sterilized by the water generation skid 105. Thus, the water generation skid 105 may include various processing components.
[0067] In some embodiments, the water generating skid 105 includes a multi-media filter stage for removing particulate matter from the water. In some embodiments, the multi-media filter may be configured to remove particles having a size or diameter of 10 μm or greater. In some embodiments, the multi-media filter may be configured to remove particles having a size or diameter of 5 μm or greater. The multi-media filter may include multiple stages or layers to progressively remove particles of progressively smaller sizes. For example, the multi-media filter may include one or more gravel layers, one or more garnet layers, one or more anthracite layers, one or more coarse sand layers, one or more fine sand layers, and / or combinations thereof. In some embodiments, the media layers may be pre-backwashed and drained. In some embodiments, each media layer may be arranged and selected for specific gravity in a manner that allows for self-contained re-stratification after backwashing. For example, the media layers may be arranged by specific gravity in ascending order from top to bottom.
[0068] In some embodiments, the water generating skid 105 includes a water softener stage configured to remove hardness ions from the water. 2+ ), magnesium ion (Mg 2+ ), and / or other metal ions from the water. In some embodiments, the water softener is configured to remove calcium and magnesium ions through ion exchange. For example, the water can be passed through a filter bed containing resin beads (e.g., beads containing NaCO2 particles), thereby removing Ca 2+ Cations and Mg 2+ Cations are added to the beads (e.g., COO - anion) and sodium cation (Na + In some embodiments, the water generating skid 105 releases, for example, Ca from the feedwater. 2+ Cations and Mg 2+The water softener may further include a brine tank and an eductor in communication with the water softener and configured to regenerate the water softener to maintain a level of NaCO2 particles for continuous removal of cations. In an additional embodiment, the water softener may be configured to treat the water with hydrated lime, e.g., Ca(OH)2, and soda ash, e.g., Na2CO3, to precipitate calcium as CaCO3 and magnesium as Mg(OH)2.
[0069] In some embodiments, the water production skid 105 includes a carbon bed filter stage. In some embodiments, the carbon bed filter is configured to remove chlorine and other trace organic compounds from the water. In some embodiments, the carbon bed filter is configured to break down chloramines (e.g., NH2Cl, NHCl2, NCl3) in the water into chlorine, ammonia, and / or ammonium.
[0070] In some embodiments, the water generation skid 105 comprises one or more mixed deionization (DI) beds configured to remove dissolved ammonia, CO2, and / or trace charged compounds and elements.
[0071] In some embodiments, the water generating skid 105 includes additional types of ion exchange beds to remove organic compounds, as would be apparent to one of ordinary skill in the art. The ion exchange beds may include resin beads of various sizes and characteristics to remove different types of particles. For example, the ion exchange beds may include strong acid cation exchange resins, weak acid cation exchange resins, strong base anion exchange resins, weak base anion exchange resins, and / or chelating resins.
[0072] In some embodiments, the water production skid 105 includes a reverse osmosis filtration stage configured to remove trace compounds, ammonium, carbon particulates and / or other particulate matter, microorganisms, and / or endotoxins from the water. For example, the reverse osmosis stage may include a semi-permeable membrane and a pump configured to apply a pressure in the water that is greater than the osmotic pressure to cause diffusion of the water through the membrane. Because the effectiveness of reverse osmosis depends on pressure, solute concentration, and other conditions, the reverse osmosis filtration stage may include one or more sensors configured to monitor conditions within the reverse osmosis unit. For example, the reverse osmosis filtration stage may include an inlet conductivity monitor, a permeate conductivity monitor, a concentrate flow meter, a permeate flow meter, a suction pressure indicator, a high pressure kill switch, and / or an instrument air pressure switch.
[0073] In some embodiments, the water generating skid 105 includes an ultraviolet (UV) light stage configured to deactivate microorganisms in the water. For example, the water generating skid 105 may include one or more UV light sources configured to emit UV light at wavelengths of 185 nm, 254 nm, 265 nm, and / or additional wavelengths configured to deactivate microorganisms. In some embodiments, the UV light source may include a quartz lamp sleeve over the UV light source to insulate the UV light source from temperature changes. In some embodiments, the UV light stage provides microwatt-seconds per square centimeter (μW-s / cm) that can deactivate microorganisms throughout the entire volume of water within the UV light stage. 2 The UV light stage is configured to emit light at a dose of about 1000 nm. The dose of light emitted within the UV light stage may be based on the internal volume, the light intensity of the one or more UV light sources, and the flow rate of water through the UV light stage. In some embodiments, the UV light stage may include an internal baffle (e.g., a helical baffle or a static blender) to facilitate thorough mixing of the water through the UV light stage, thereby causing further exposure of the water to the UV light.
[0074] In some embodiments, the water generation skid 105 includes one or more filter cartridges for removing contaminants from drinking water. For example, one or more of the various stages of the water generation skid 105 described herein may be provided in the form of a cartridge.
[0075] In some embodiments, the water generation skid 105 includes additional components that would be apparent to one of ordinary skill in the art for controlling, maintaining, and regulating the flow of water through the various stages and treating the water in the manner described herein. For example, the water generation skid 105 may include distribution pumps, booster pumps, centrifugal pumps, transmitters, valves, power sources, sensors, and electrical circuitry required to treat the water and maintain the proper conditions in the various stages of the water generation skid 105.
[0076] Water Storage Tank 1A , the water generation skid 105 is in fluid communication with a storage tank 110 configured to receive the lab water from the water generation skid 105 and store the water therein. In some embodiments, the storage tank 110 is configured to maintain the quality of the lab water after processing by the water generation skid 105. Additionally, the storage tank 110 may be configured to distribute the water to the distribution loops, as described further herein. The storage tank may also be in fluid communication with piping and outlets that are not part of the primary and secondary distribution loops. In some embodiments, the storage tank may include one or more valves to selectively allow fluid to pass from the storage tank 110 to the primary and secondary distribution loops.
[0077] In some embodiments, the lab water received by the storage tank 110 from the water production skid 105 may have its temperature elevated. For example, various filtration and treatment steps described herein may result in lab water having an elevated temperature. Thus, the water in the storage tank 110 may be passively cooled to ambient temperature over time upon entering the main distribution loop 115 and / or may be actively cooled using a chiller, as described further herein. In some embodiments, the storage tank 110 may include a chiller to actively cool the lab water.
[0078] Main and sub-distribution loops 1A , the main distribution loop 115 is in fluid communication with the storage tank 110 at a first end. The main distribution loop 115 may be configured to receive lab water from the storage tank 110 at the first end and circulate the water through the main distribution loop 115. In some embodiments, the main distribution loop 115 is further in fluid communication with the storage tank 110 at a second end. The main distribution loop 115 may be configured to return the lab water to the storage tank 110 at the second end after circulating the water through the main distribution loop 115.
[0079] In some embodiments, the main distribution loop 115 is configured to maintain the laboratory water in the distribution loop at a baseline temperature. For example, the baseline temperature can be about room temperature. In another example, the baseline temperature can be between about 18° C. and about 25° C. In a further example, the baseline temperature can be less than room temperature, for example, between about 18° C. and about 22° C.
[0080] In some embodiments, the main distribution loop 115 includes a heat exchanger or chiller 135 configured to maintain the lab water at a baseline temperature. For example, the chiller 135 may be in proximity to the main distribution loop 115 and circulate a fluid through the chiller 135 to cool the lab water as needed to maintain the baseline temperature. The fluid in the chiller 135 may be chilled glycol (e.g., propylene glycol), chilled water, or another fluid capable of transferring heat from the lab water. It should be understood that no fluid is exchanged between the chiller 135 and the main distribution loop 115. Rather, the fluids in the chiller 135 and the main distribution loop 115 exchange heat through one or more interfaces between the chiller 135 and the main distribution loop 115 without direct contact and / or transfer.
[0081] In some embodiments, the lab water stored in the storage tank 110 may be passively cooled and maintained at a baseline temperature, for example, at or near 25° C. Thus, the chiller 135 may not be running all the time. In some embodiments, the chiller 135 is activated when a large volume of lab water is produced to chill the fresh lab water to the baseline temperature. In some embodiments, the main distribution loop 115 is configured to maintain the lab water at a temperature different from the temperature of the water in the storage tank 110.
[0082] 1B, a detailed view of the cooling device 135 is depicted according to one embodiment. As shown, the cooling device 135 may include one or more conduits 140 extending in fluid communication with a source 145 of cooling fluid, for example, chilled glycol, chilled water, or another coolant that would be apparent to one of ordinary skill in the art. A portion of the main distribution loop 115 may pass through the cooling device 135 in close proximity to the conduits 140 such that the water in the main distribution loop 115 is cooled by heat transfer with the cooling fluid circulating through the conduits 140. In some embodiments, the main distribution loop 115 and the conduits 140 may share an interface between the main distribution loop 115 and the conduits 140 for heat transfer. In some embodiments, the conduits 140 may pass the cooling fluid to an air separator and / or a refill unit for refilling the cooling fluid. The cooling fluid may then return to the source 145 for reuse. In some embodiments, the conduits 140 may pass the cooling fluid to a disposal site. In some embodiments, the cooling system 135 may be configured as a closed recirculation system. In some embodiments, the cooling system 135 may be configured as an open recirculation system.
[0083] The cooling system 135 may include additional components for controlling the movement and / or monitoring the fluid. For example, the cooling system 135 may include one or more pumps, valves (e.g., two-way valves), power sources, sensors, and / or electrical circuitry.
[0084] In some embodiments, multiple cooling devices 135 may be operatively connected to the main distribution loop 115 to provide more consistent and / or more accurate temperature control. Additionally, although the cooling devices 135 are depicted near the beginning of the main distribution loop 115, it should be understood that the cooling devices 135 may join the main distribution loop 115 at any point along the loop.
[0085] In some embodiments, the cooling device 135 may include a compressor, an evaporator, and / or a condenser. Additional ways of maintaining temperature within the distribution loop are contemplated as would be apparent to one of ordinary skill in the art.
[0086] In some embodiments, the secondary distribution loop 120 is in fluid communication with the primary distribution loop 115 at a first end of the secondary distribution loop. The secondary distribution loop 120 may be configured to receive lab water from the primary distribution loop 115. In some embodiments, the secondary distribution loop 120 is configured to maintain the lab water in the distribution loop at a set point temperature that is different from the baseline temperature of the storage tank 110 and / or the primary distribution loop 115. For example, if the lab water is maintained at about 18° C. to about 25° C. by the storage tank 110 and the primary distribution loop 115, the secondary distribution loop 120 may maintain the lab water at between about 53° C. to about 57° C. In some embodiments, the set point temperature of the secondary distribution loop 120 is variable and may be adjusted based on input from a user and / or parameters associated with a particular procedure.
[0087] In some embodiments, the secondary distribution loop 120 comprises a heat exchanger 150 configured to raise the temperature of the laboratory water received from the primary distribution loop 115 to a set point temperature and maintain the water at the set point temperature. For example, the heat exchanger 150 may circulate a heated fluid (e.g., steam or hot water) through the heat exchanger 150 in proximity to the secondary distribution loop 120 to continuously heat the laboratory water and maintain a set point temperature, e.g., about 57°C. In some embodiments, the heat exchanger 150 may include or be in fluid communication with a boiler for receiving the heated fluid, e.g., steam. It should be understood that fluid is not exchanged between the heat exchanger 150 and the secondary distribution loop 120. Rather, the fluids of the heat exchanger 150 and the secondary distribution loop 120 exchange heat through one or more interfaces between the heat exchanger 150 and the secondary distribution loop 120 without direct contact and / or transfer.
[0088] 1C, a detailed view of the heat exchanger 150 is depicted according to one embodiment. As shown, the heat exchanger 150 may include one or more conduits 155 extending therethrough and in fluid communication with a source 160 of a heating fluid, e.g., steam, hot water, or another heating fluid that would be apparent to one of ordinary skill in the art. A portion of the secondary distribution loop 120 may pass through the heat exchanger 150 in close proximity to the conduit 155, such that the water in the secondary distribution loop 120 is heated by heat transfer with the heating fluid circulating through the conduit 155 to continuously heat the laboratory water and maintain a set point temperature, e.g., about 57°C. In some embodiments, the secondary distribution loop 120 and the conduit 155 may share an interface between the secondary distribution loop 120 and the conduit 155 for heat transfer. In some embodiments, the conduit 155 may pass the heating fluid to a refill unit to refill the heating fluid. The heating fluid may then return to the source 160 for reuse. In some embodiments, conduit 155 may pass the heated fluid to a disposal site. In some embodiments, heat exchanger 150 may be configured as a closed recirculation system. In some embodiments, heat exchanger 150 may be configured as an open recirculation system. Various types of heating units and configurations thereof may be implemented herein as would be known to one of ordinary skill in the art.
[0089] The heat exchanger 150 may include additional components for controlling and / or monitoring the heating fluid. For example, the heat exchanger 150 may include one or more pumps, valves (e.g., two-way valves), power sources, sensors, and / or electrical circuitry.
[0090] In some embodiments, multiple heat exchangers 150 may be operatively connected to the secondary distribution loop 120 to provide more consistent and / or more accurate temperature control. Additionally, although the heat exchanger 150 is depicted proximate an end portion of the secondary distribution loop 120, it should be understood that the heat exchanger 150 may be joined with the secondary distribution loop 120 at any point along the loop.
[0091] It should be understood that the elevated temperature in the secondary distribution loop 120 is an optional feature that can be activated and deactivated. Thus, for a particular period of time, the lab water in the secondary distribution loop may not be elevated. In some embodiments, the secondary distribution loop 120 may have a baseline temperature that substantially matches the primary distribution loop 115 and / or the storage tank 110. For example, the temperature of the lab water in the secondary distribution loop 120 may be an ambient temperature and / or a chilled temperature as described herein.
[0092] In some embodiments, the secondary distribution loop 120 may circulate the lab water back to the storage tank 110 to recycle lab water not used at the set point temperature. In some embodiments, the water from the secondary distribution loop 120 may be in fluid communication with the primary distribution loop 115 at a second end of the secondary distribution loop 120. For example, the second end of the secondary distribution loop 120 may connect back to a channel that joins with the primary distribution loop 115, as described further herein. In another example, the second end of the secondary distribution loop 120 may connect separately to the primary distribution loop 115. Thus, the water from the secondary distribution loop 120 may return to the primary distribution loop 15 and ultimately back to the storage tank 110 through the primary distribution loop 15. In some embodiments, the secondary distribution loop 120 may be in direct fluid communication with the storage tank 110 and may return the water directly to the storage tank 110. In some embodiments, the heat exchanger of the secondary distribution loop 120 and / or additional heat exchangers may cool the lab water in the secondary distribution loop 120 back to a baseline temperature before discharging it to the main distribution loop 115 and / or the storage tank 110. In some embodiments, the heat exchanger of the main distribution loop 115 may return the heated water received from the secondary distribution loop 120 to a baseline temperature. Additional manners of maintaining temperature within a distribution loop are contemplated as would be apparent to one having ordinary skill in the art.
[0093] By recycling heated lab water from the secondary distribution loop 120 back to the main distribution loop 115 and / or storage tank 110, lab water is conserved and waste is minimized. Typically, production of highly purified lab water is expensive, time consuming, and energy intensive due to the equipment, consumables, and precision required. Optionally, costs may be significantly reduced by recycling heated lab water from the secondary distribution loop 120 as described herein. With systems and methods as described, immediate availability of water and efficient use of water may be achieved simultaneously.
[0094] In some embodiments, the primary distribution loop 115 and the secondary distribution loop 120 are in selective communication through one or more valves 130. For example, as shown in FIG. 1A, a valve 130A may be positioned in a channel connecting the secondary distribution loop 120 to the primary distribution loop 115. Thus, after lab water is transferred from the primary distribution loop 115 to the secondary distribution loop 120, the lab water in the secondary distribution loop 120 may be isolated from the primary distribution loop 115 by closing the valve 130A to maintain the water in the primary distribution loop 115 at a separate set point temperature. As shown, the water in the secondary distribution loop 120 may circulate within the secondary distribution loop 120 while the valve 130A is closed. As the water is consumed, the valve 130A may be opened to replenish the water supply in the secondary distribution loop. Additionally, a second valve 130B may be located near the end of the secondary distribution loop 120 to allow or prohibit flow through the secondary distribution loop 120. When the use of water at the set point temperature is completed in a given example, valves 130A / 130B may be opened to return the water to the main distribution loop 115.
[0095] The primary and secondary loop systems can be operated manually, manually and automatically, and fully automatically. For automatic operation, computer processors and electronically controlled valves and heat exchangers can be employed. Exemplary approaches for automatic control using computer techniques are provided herein.
[0096] In some embodiments, the valve 130 is in electrical communication with the processor and may be controlled by the processor via electrical signals, as further described herein. In some embodiments, the valve 130 is operably connected to an actuator to open and close the valve. In some embodiments, the valve 130 may be a bi-directional valve. In some embodiments, the valve 130 may be a zero static tee valve. In some embodiments, the valve 130 may be a solenoid valve. In some embodiments, the valve 130 may be a servo motor operably connected to open and close the valve. Additional types of valves are contemplated herein as would be apparent to one of ordinary skill in the art.
[0097] 1A, the secondary distribution loop 120 may form a complete loop in a "chase the tail" configuration to allow circulation within the secondary distribution loop 120. In additional embodiments, inflow and outflow to and from the secondary distribution loop 120 may occur through separate connecting channels. Thus, each connecting channel may include a valve 130. In additional embodiments, the connecting channels may be directly joined between the secondary distribution loop 120 and the storage tank 110. Thus, the connecting channels may include a valve 130 to selectively return water to the storage tank 110.
[0098] The main distribution loop 115 and the secondary distribution loop 120 may further include one or more outlets 125 for dispensing laboratory water. The outlets 125 may be provided throughout various dedicated spaces within the facility. In some embodiments, the outlets 125 of each distribution loop 115 / 120 are intended for a unique purpose. For example, cold or ambient water in the main distribution loop 115 may be sufficient for cleaning, rinsing, and chemical and / or biotechnology processes. However, heated water at a precisely controlled temperature may be required for media preparation, buffer preparation, etc.
[0099] In some embodiments, at least some of the outlets 125 may be manual outlets that can be manually operated by a user, such as a faucet, a sink, a wall mounted drain, a media / buffer outlet, etc. In some embodiments, at least some of the outlets 125 may be automatic outlets that connect a supply of laboratory water to equipment such as a refrigerator, washing equipment for glassware and other lab supplies, an incubator, and / or an autoclave machine. It should be understood that any type of outlet 125 may be configured as manual or automatic according to function or preference.
[0100] In some embodiments, the main distribution loop 115 may include one or more pumps dedicated to circulating water in the main distribution loop 115. In some embodiments, the secondary distribution loop 120 may include one or more pumps dedicated to circulating water in the secondary distribution loop 120. For example, as shown in FIG. 1A, water may circulate in the secondary distribution loop 120 while valve 130A is closed and valve 130B is open. Thus, the secondary distribution loop 120 may have a dedicated pump so that water may be circulated even when isolated from the main distribution loop. In some embodiments, the one or more pumps of the secondary distribution loop 120 are centrifugal pumps. However, additional types of pumps may be utilized herein, as would be apparent to one of ordinary skill in the art.
[0101] The piping forming the main distribution loop 115, the secondary distribution 120, the outlet 125, and / or additional piping in the system 100 may comprise carbon steel piping and fittings. In some embodiments, the piping may be insulated with, for example, fiberglass insulation and / or a jacket to efficiently maintain the temperature of the water within the piping. In some embodiments, the jacket may be a PVC jacket (e.g., for indoor piping) or an aluminum jacket (e.g., for outdoor piping).
[0102] In some embodiments, the distribution loop 115 / 120 may be operatively connected to one or more exhaust fans configured to exhaust energy from the distribution system. For example, two exhaust fans may operate simultaneously to exhaust heat and maintain the condition of the distribution system. In some embodiments, the exhaust fans may form an energy recovery unit, including one or more coils and one or more strobe fans, that may recycle the energy (e.g., heat) exhausted from the distribution system for heating air within the facility and for other purposes.
[0103] Each of the distribution loops 115 / 120 may include an array of sensors and / or alarms configured to monitor one or more parameters in the laboratory water. For example, the array of sensors may be configured to monitor temperature, conductivity, total organic carbon, distribution pressure, and / or loop pressure. In some embodiments, a notification or alarm may sound when one or more parameters are approaching or outside of a desired range.
[0104] Each of the distribution loops 115 / 120 may be configured with sensors and electronic control components configured to regulate the laboratory water in a proportional-integral-derivative (PID) control loop. In the PID loop, a sensor may be used to continuously evaluate deviations from set parameters and a control device may implement corrections to restore the set parameters with minimal delay. For example, a temperature sensor may be used to monitor temperature in a substantially continuous manner and a heat exchanger may be used to implement corrections as necessary to maintain a baseline and / or set point temperature for each distribution loop.
[0105] It should be understood that any of the various valves described herein with respect to components of system 100 may comprise any type of valve that would be known to one of ordinary skill in the art. For example, the valves may comprise bidirectional valves, zero static tee valves, solenoid valves, servo motor controlled valves, etc.
[0106] In some embodiments, any of the disclosed features or components may be provided redundantly for any of the purposes described herein and utilized to achieve more consistent conditions and / or reduce the probability of failure. For example, heat exchangers, fans, distribution pumps, sensors, etc. may be provided in duplicate or triplicate for any of the purposes described herein.
[0107] It should be understood that a high degree of specificity is required in preparing materials, especially in virus production processes. Various production processes can be highly dependent on the temperature of the water and other materials utilized, and the processes can also be time-dependent. Thus, while conventional practice may involve drawing water from a common source and heating or cooling as needed, typical equipment may not be equipped with sensors and / or feedback systems to allow fine control of temperature in the manner required. Furthermore, time-dependent production processes involving several steps may not tolerate the delays associated with conventional methods of preparing temperature-specific laboratory water. Thus, the systems disclosed herein advantageously eliminate the problems of conventional systems and methods by providing an accurate temperature-controlled water source that can be pre-set, maintained, and made available on demand. Furthermore, unused temperature-controlled water is cooled and recycled such that waste of water purified by the systems and methods herein is minimized.
[0108] Control system and method The laboratory water distribution loop system 100 described herein may be controlled via a process control system. In some embodiments, the process control system comprises one or more processors and a non-transitory computer readable medium storing instructions executable by the one or more processors. In some embodiments, the process control system comprises one or more programmable logic controllers (PLCs).
[0109] The process control system may further include one or more interface units, or operator interface terminals (OIT) 165, for a user or operator to interface with the system 100, including receiving information and / or providing input. In some embodiments, the OIT 165 may be locally connected to the equipment skid, for example, mounted on a NEMA 4 control panel on the equipment skid. In some embodiments, for example, as shown in FIG. 1A, the OIT 165 may be remotely located and connected to the laboratory water distribution loop system 100 via a wired or wireless connection, as would be readily known to one of ordinary skill in the art. In some embodiments, the OIT 165 may be embodied as a software application on a mobile device, such as a tablet or cell phone.
[0110] In some embodiments, the OIT 165 includes a display and input devices, such as a touch screen, keyboard, and / or keypad. In some embodiments, the OIT 165 may be used to provide operator monitoring and control of the equipment. In some embodiments, the OIT 165 may be used to set temperatures within sections of the laboratory water distribution loop system 100. In some embodiments, the OIT 165 may be used to view system status, alerts, notifications, alarms, etc.
[0111] The OIT 165 may additionally include various components to perform the various functions described herein, as would be apparent to one of ordinary skill in the art, including, but not limited to, transmitters, solenoids, analyzers, power sources, sensors, and electrical circuitry, as well as emergency controls.
[0112] Referring now to FIG. 2, a flow diagram of an illustrative computer-implemented method for regulating water temperature in a secondary distribution loop of a water distribution system is depicted, according to one embodiment. The method 200 includes maintaining 210 a first amount of water at a baseline temperature in a main laboratory water distribution loop of a distribution system; receiving 220 an input related to a set point temperature of the laboratory water through an input device; optionally transferring 225 a second amount of water from the main distribution loop to a secondary distribution loop of the distribution system; heating 230 the second amount of water in the secondary distribution loop of the distribution system from the baseline temperature to a set point temperature; maintaining 240 the second amount of water at the set point temperature for a period of time; holding 250 the first amount of water in the main distribution loop of the distribution system at the baseline temperature for a period of time; cooling 260 the second amount of water from the set point temperature to the baseline temperature in response to a trigger; and optionally recycling 265 the second amount of water by transferring 265 the second amount of water in the secondary distribution loop to one or more of the main distribution loop or a storage tank.
[0113] In some embodiments, the distribution system may include a storage tank, a main distribution loop in fluid communication with the storage tank, and a secondary distribution loop extending from the main distribution loop and back to the main distribution loop. For example, the water distribution system may be a laboratory water distribution loop system 100, as shown in FIG. 1A.
[0114] In some embodiments, maintaining 210 the first amount of water in the main distribution loop at the baseline temperature may further include first transferring the first amount of water from a storage tank to the main distribution loop or refilling the first amount of water in the main distribution loop from a storage tank and cooling the first amount of water to the baseline temperature using a cooling device, e.g., as described herein in connection with FIGS. 1A and 1B.
[0115] In some embodiments, receiving 220 an input related to a setpoint temperature may include receiving an input from a user via the OIT to activate a heating cycle. In some embodiments, the input may include pressing a button to activate production of heated RODI (i.e., "HRODI") at the setpoint temperature. In some embodiments, the command selected by the user is generic (e.g., "HEAT") and does not specify a setpoint temperature. Rather, the setpoint temperature is fixed and known to the process control system. In some embodiments, the user may be able to set or input a desired setpoint temperature.
[0116] In some embodiments, the optional step 225 of transferring a second amount of water from the primary distribution loop to the secondary distribution loop may include first actuating (e.g., by a processor) one or more valves from a closed position to an open position to allow the transfer of water between the primary and secondary distribution loops, and then moving one or more valves from an open position to a closed position to isolate the primary and secondary distribution loops. In some embodiments, the optional step 225 of transferring a second amount of water from the primary distribution loop to the secondary distribution loop may include refilling water in the secondary distribution loop from the primary distribution loop.
[0117] In some embodiments, the main and secondary distribution loops are isolated during the maintaining step 210, the heating step 230, the maintaining step 240, the holding step 250, and the cooling step 260. For example, the method 200 may include actuating (e.g., by a processor) one or more valves to isolate the main and secondary distribution loops. In some embodiments, the distribution loops remain isolated until the water in both distribution loops is normalized at or near a baseline temperature.
[0118] In some embodiments, the heating step 230, the maintaining step 240, the holding step 250, and the cooling step 260 are facilitated by one or more heat exchangers in the distribution system. For example, the distribution system may include a heat exchanger, as described in detail with respect to the laboratory water distribution loop system 100 of Figures 1A, 1B, and 1C.
[0119] The cooling step 260 may be triggered in a variety of ways. In some embodiments, the trigger includes the completion of a predetermined time limit. For example, the system may have preprogrammed time limits, e.g., 15 minutes, 30 minutes, 60 minutes, more than 60 minutes, or individual values or rangers therebetween. In another example, the user may input the time limit at a particular instance. Thus, the trigger may be a notification from a timer that a period of time has reached a predetermined time limit and / or an inputted time limit. In some embodiments, the trigger includes additional input from the user related to the termination of the HRODI request. For example, the user may press a button to deactivate the HRODI (e.g., a "COOL" button). In some embodiments, the trigger includes an error or alarm, e.g., an alarm alert of an abnormal or dangerous condition in the water. For example, the error or alarm may be received from a computing device associated with the distribution system, the water in the distribution system, and / or the facility housing the distribution system (e.g., environmental conditions).
[0120] In some embodiments, the interface unit may provide additional functionality. In some embodiments, HRODI requests may be planned or scheduled for a particular time in the future. For example, HRODI requests may be manually scheduled for a future time based on planned activities. In some embodiments, rather than entering individual requests, HRODI requests may be planned or initiated based on a particular production process. For example, if a formalized process for producing a particular composition is planned or in progress, the process control system may be programmed based on a database of the formal production process to activate HRODI requests according to the formal production process. In some embodiments, the production process may require multiple HRODI requests at discrete time intervals. Thus, HRODI requests may be activated based on time. In some embodiments, the process control system may communicate with additional computing components and schedule or initiate HRODI requests based on information received from those computing components. Thus, HRODI requests may be initiated based on an indicated stage of the production process and / or additional information.
[0121]
[0031] Referring now to Figure 3, a flow diagram of an illustrative computer-implemented method of regulating a water temperature in a main distribution loop of a water distribution system is depicted, according to one embodiment. It should be understood that method 300 may also illustrate a sub-process of step 210 of method 200 discussed in connection with Figure 2, i.e., maintaining a first quantity of water in the main distribution loop at a baseline temperature. Method 300 includes receiving 310 an input related to a baseline temperature of the water through an input device, cooling 320 the first quantity of water in the main distribution loop of the distribution system from an initial temperature to the baseline temperature, continuously maintaining 330 the first quantity of water at the baseline temperature for a period of time, and terminating 340 the temperature control in response to a trigger.
[0122] In some embodiments, the distribution system may include a storage tank, a main distribution loop in fluid communication with the storage tank, and a secondary distribution loop extending from the main distribution loop and back to the main distribution loop. For example, the water distribution system may be a laboratory water distribution loop system 100, as shown in FIG. 1A.
[0123] In some embodiments, receiving input related to the baseline temperature 310 may include receiving input from a user via the OIT to activate a cooling cycle. In some embodiments, the input may include pressing a button to activate production of cooled RODI (i.e., "CRODI") at the baseline temperature. In some embodiments, the command selected by the user is generic (e.g., "COOL") and does not specify a baseline temperature. Rather, the baseline temperature is selected and known to the process control system. In some embodiments, the user may be able to set or input a desired baseline temperature. In some embodiments, the system is configured to continuously maintain the water at the baseline temperature while the system is operating. The baseline temperature selected is typically room temperature, approximately 68°F to 76°F. Thus, the input may include activating the system, for example, an initial activation, a daily activation, or an activation from a sleep or hibernation mode.
[0124] In some embodiments, the main and secondary distribution loops are isolated during the cooling step 320 and the maintaining step 330. For example, the method 200 may be performed simultaneously to control the temperature of the water in the secondary distribution loop without affecting the process 300 for maintaining the baseline temperature of the main distribution loop. One or more valves may be actuated (e.g., by a processor) to isolate the main and secondary distribution loops. In some embodiments, the distribution loops remain isolated until the water in both distribution loops is normalized at or near the baseline temperature. In additional embodiments, the water in both distribution loops may be cooled and maintained at the baseline temperature by the process 300, for example, when there is no active HRODI request.
[0125] In some embodiments, the cooling 320 and maintaining 330 steps are facilitated by one or more chillers or heat exchangers in the distribution system. For example, the distribution system may include a chiller, as described in detail with respect to the laboratory water distribution loop system 100 of FIGS. 1A-1B.
[0126] The termination step 340 may be triggered in various manners. In some embodiments, the trigger includes the completion of a predetermined time limit. For example, the system may have preprogrammed time limits, such as 15 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, 24 hours, more than 24 hours, or individual values or rangers therebetween. In another example, the user may input the time limit at a particular instance. Thus, the trigger may be a notification from a timer that a period of time has reached the predetermined time limit and / or the inputted time limit. In some embodiments, the trigger includes additional input from the user related to the termination of the CRODI request. For example, the user may press a button to deactivate CRODI (e.g., an "END" button). In some embodiments, the trigger includes an error or alarm, such as an alarm alert of an abnormal or dangerous condition in the water. For example, the error or alarm may be received from a computing device associated with the distribution system, the water in the distribution system, and / or the facility housing the distribution system (e.g., environmental conditions).
[0127] In some embodiments, the interface unit may provide additional functionality. In some embodiments, CRODI requests may be planned or scheduled for a particular time in the future. For example, CRODI requests may be manually scheduled for a future time based on planned activities. In some embodiments, rather than entering individual requests, CRODI requests may be planned or initiated based on a particular production process. For example, if a formalized process for producing a particular composition is planned or in progress, the process control system may be programmed based on a database of the formal production process to activate CRODI requests according to the formal production process. In some embodiments, the production process may require multiple CRODI requests at discrete time intervals. Thus, CRODI requests may be activated based on time. In some embodiments, the process control system may communicate with additional computing components and schedule or initiate CRODI requests based on information received from those computing components. Thus, CRODI requests may be initiated based on an indicated stage of the production process and / or additional information.
[0128] As discussed herein, valves between the main and secondary distribution loops may be selectively opened and closed by a processor to allow for isolation of the distribution loops and maintain separate water temperatures in each of the distribution loops. Referring now to FIG. 4, a flow diagram of an illustrative computer-implemented method 400 for regulating flow in the main and secondary distribution loops is depicted, according to one embodiment. The processor may receive 410 a signal indicative of an active HRODI request and close 420 one or more valves between the main and secondary distribution loops based on the HRODI request. Thus, the temperature of the water in the secondary distribution loop may be increased from a baseline temperature to a setpoint temperature without affecting the temperature of the water in the main distribution loop, which remains at the baseline temperature. The processor may receive 430 a signal indicative of completion of the HRODI request and determine 440 the temperature of the water in the secondary distribution loop. In step 450, the processor determines whether the temperature of the water in the secondary distribution loop is not equal to the baseline temperature. If a negative determination is made, the processor may return to step 440 after a delay period, for example, one minute. However, various delay periods may be utilized, as would be apparent to one of ordinary skill in the art. If a positive determination is made and the temperature of the water in the secondary distribution loop is substantially equal to the baseline temperature, the processor may proceed to step 460 and open the valve. Thus, the water in the secondary distribution loop may return to the primary distribution loop and / or the storage tank. In embodiments where the secondary distribution loop returns directly to the storage tank, process 400 may be implemented with minor modifications to control a first valve between the primary and secondary distribution loops and a second valve between the secondary distribution loop and the storage tank.
[0129] Laboratory Water Distribution Loop System 500 Referring now to Figure 5, an exemplary laboratory water distribution loop system 500 is depicted according to an embodiment. As shown in Figure 5, the laboratory water distribution loop system 500 comprises a laboratory water generation skid 505, a storage tank 510 in fluid communication with the laboratory water generation skid 505, a CRODI water distribution loop 515 in fluid communication with the storage tank 510, and a HRODI water distribution loop 520 in fluid communication with the storage tank 510. According to some embodiments of the present disclosure, the system 500 may also include one or more additional HRODI water distribution loops 520 in fluid communication with the storage tank 510. The system further includes one or more outlets 525, each outlet 525 connected to one of the CRODI water distribution loops 515 and the HRODI water distribution loops 520 for discharging water from that distribution loop. CRODI water distribution loop 515 and HRODI water distribution loop 520 may be in selective communication with storage tank 510 via one or more valves 530 (e.g., valves 530a-530d). As shown, CRODI water distribution loop 515 includes a chiller 535a configured to maintain the lab water at a first (e.g., baseline) set point temperature. Similarly, HRODI water distribution loop 520 may include a heat exchanger 550 configured to increase the temperature of the lab water received from storage tank 510 to a second (e.g., elevated) set point temperature and maintain the water at the second set point temperature. According to some embodiments of the present disclosure, HRODI water distribution loop 520 may include an optional chiller 535b, shown in dashed lines, configured to reduce the temperature of the lab water in HRODI water distribution loop 520 to another set point temperature (e.g., baseline temperature) before returning the lab water to storage tank 510. The system 500 further comprises one or more interface units 565, or operator interface terminals (OITs), for a user or operator to interface with the system 500, including receiving information and / or providing input for control of the system.
[0130] Water Generation Skid The water generation skid 505 may include a water source for receiving potable water or other water that may be treated into laboratory water. Various processing steps may be used to generate laboratory water that preferably meets ASTM Type II standards. For example, potable water may be filtered by various media, softened, dechlorinated, deionized, distilled, and / or sterilized by the water generation skid 505. Thus, the water generation skid 505 may include various processing components.
[0131] In some embodiments, the water generating skid 505 includes a multi-media filter stage for removing particulate matter from the water. In some embodiments, the multi-media filter may be configured to remove particles having a size or diameter of 10 μm or greater. In some embodiments, the multi-media filter may be configured to remove particles having a size or diameter of 5 μm or greater. The multi-media filter may include multiple stages or layers to progressively remove particles of progressively smaller sizes. For example, the multi-media filter may include one or more gravel layers, one or more garnet layers, one or more anthracite layers, one or more coarse sand layers, one or more fine sand layers, and / or combinations thereof. In some embodiments, the media layers may be pre-backwashed and drained. In some embodiments, each media layer may be arranged and selected for specific gravity in a manner that allows for self-contained re-stratification after backwashing. For example, the media layers may be arranged by specific gravity in ascending order from top to bottom.
[0132] In some embodiments, the water generating skid 505 comprises a water softener stage configured to remove hardness ions from the water. In some embodiments, the water softener is configured to remove calcium ions (Ca2+), magnesium ions (Mg2+), and / or other metal ions from the water. In some embodiments, the water softener is configured to remove calcium and magnesium ions through ion exchange. For example, the water may be passed through a filter bed comprising resin beads (e.g., beads comprising NaCO2 particles), whereby Ca2+ and Mg2+ cations bind to the beads (e.g., COO- anions) and release sodium cations (Na+) into the water. In some embodiments, the water generating skid 505 may further comprise a brine tank and an eductor in communication with the water softener and configured to regenerate the water softener, for example, to maintain a level of NaCO2 particles to continuously remove Ca2+ and Mg2+ cations from the feedwater. In additional embodiments, the water softener may be configured to treat water with hydrated lime, e.g., Ca(OH)2, and soda ash, e.g., Na2CO3, to precipitate calcium as CaCO3 and magnesium as Mg(OH)2.
[0133] In some embodiments, the water production skid 505 includes a carbon bed filter stage. In some embodiments, the carbon bed filter is configured to remove chlorine and other trace organic compounds from the water. In some embodiments, the carbon bed filter is configured to break down chloramines (e.g., NH2Cl, NHCl2, NCl3) in the water into chlorine, ammonia, and / or ammonium.
[0134] In some embodiments, the water generation skid 505 comprises one or more mixed deionization (DI) beds configured to remove dissolved ammonia, CO2, and / or trace charged compounds and elements.
[0135] In some embodiments, the water generating skid 505 includes additional types of ion exchange beds to remove organic compounds, as would be apparent to one of ordinary skill in the art. The ion exchange beds may include resin beads of various sizes and characteristics to remove different types of particles. For example, the ion exchange beds may include strong acid cation exchange resins, weak acid cation exchange resins, strong base anion exchange resins, weak base anion exchange resins, and / or chelating resins.
[0136] In some embodiments, the water production skid 505 includes a reverse osmosis filtration stage configured to remove trace compounds, ammonium, carbon particulates and / or other particulate matter, microorganisms, and / or endotoxins from the water. For example, the reverse osmosis stage may include a semi-permeable membrane and a pump configured to apply a pressure in the water that is greater than the osmotic pressure to cause diffusion of the water through the membrane. Because the effectiveness of reverse osmosis depends on pressure, solute concentration, and other conditions, the reverse osmosis filtration stage may include one or more sensors configured to monitor conditions within the reverse osmosis unit. For example, the reverse osmosis filtration stage may include an inlet conductivity monitor, a permeate conductivity monitor, a concentrate flow meter, a permeate flow meter, a suction pressure indicator, a high pressure kill switch, and / or an instrument air pressure switch.
[0137] In some embodiments, the water generating skid 505 includes an ultraviolet (UV) light stage configured to deactivate microorganisms in the water. For example, the water generating skid 505 may include one or more UV light sources configured to emit UV light at wavelengths of 185 nm, 254 nm, 265 nm, and / or additional wavelengths configured to deactivate microorganisms. In some embodiments, the UV light source may include a quartz lamp sleeve over the UV light source to insulate the UV light source from temperature changes. In some embodiments, the UV light stage is configured to emit light at a dose of microwatt-seconds per square centimeter (μW-s / cm2) capable of deactivating microorganisms throughout the entire volume of water within the UV light stage. The dose of light emitted within the UV light stage may be based on the internal volume, the light intensity of the one or more UV light sources, and the flow rate of water through the UV light stage. In some embodiments, the UV light stage may include an internal baffle (e.g., a helical baffle or a static blender) to facilitate thorough mixing of the water through the UV light stage, thereby causing further exposure of the water to UV light.
[0138] In some embodiments, the water generation skid 505 includes one or more filter cartridges for removing contaminants from drinking water. For example, one or more of the various stages of the water generation skid 505 described herein may be provided in the form of a cartridge.
[0139] In some embodiments, the water generation skid 505 includes additional components that would be apparent to one of ordinary skill in the art for controlling, maintaining, and regulating the flow of water through the various stages and treating the water in the manner described herein. For example, the water generation skid 505 may include distribution pumps, booster pumps, centrifugal pumps, transmitters, valves, power sources, sensors, and electrical circuitry required to treat the water and maintain the proper conditions in the various stages of the water generation skid 505.
[0140] Water Storage Tank 5, the water generation skid 505 is in fluid communication with a storage tank 510 configured to receive laboratory water from the water generation skid 505 and store the water therein. In some embodiments, the storage tank 510 is configured to maintain the quality of the laboratory water after processing by the water generation skid 505. Additionally, the storage tank 510 may be configured to distribute the water to a distribution loop as described further herein. The storage tank may also be in fluid communication with piping and outlets that are not part of the CRODI water distribution loop 515 and the HRODI water distribution loop 520. As shown, the storage tank 510 may include one or more valves 530 for selectively allowing the flow of water between the storage tank 510 and one or more of the CRODI water distribution loop 515 (e.g., valves 530a and 530b) and the HRODI water distribution loop 520 (e.g., valves 530c and 530d).
[0141] In some embodiments, the lab water received by the storage tank 510 from the water generation skid 505 may be elevated in temperature. For example, various filtration and processing steps described herein may result in lab water having an elevated temperature. Thus, the water in the storage tank 510 may be passively cooled to ambient temperature over time, actively cooled using a chiller as it enters the CRODI water distribution loop 515, or actively heated using a heat exchanger to maintain or even increase the temperature of the water as it enters the HRODI water distribution loop 520, as further described herein. In some embodiments, the storage tank 510 may include one or more of a chiller and a heat exchanger to actively cool and / or heat the lab water.
[0142] CRODI Water Distribution Loop and HRODI Water Distribution Loop 5, the CRODI water distribution loop 515 is in fluid communication with the storage tank 510. The CRODI water distribution loop 515 may be configured to receive laboratory water from the storage tank 510 at a first end and circulate the water through the CRODI water distribution loop 515. In some embodiments, the CRODI water distribution loop 515 is further in fluid communication with the storage tank 510 at a second end. The CRODI water distribution loop 515 may be configured to return the laboratory water to the storage tank 510 at the second end after circulating the water through the CRODI water distribution loop 515.
[0143] In some embodiments, the CRODI water distribution loop 515 is configured to maintain the laboratory water in the distribution loop at a baseline temperature. For example, the baseline temperature can be about room temperature. In another example, the baseline temperature can be between about 18° C. and about 25° C. In a further example, the baseline temperature can be less than room temperature, for example, between about 18° C. and about 22° C.
[0144] In some embodiments, the CRODI water distribution loop 515 includes a cooling device 535a configured to maintain the lab water at a baseline temperature. The cooling device 535a may be structurally and / or functionally similar to the cooling device 135 described in connection with FIGS. 1A and 1B. Thus, the cooling device 535a may circulate a fluid through the cooling device 535a in close proximity to the CRODI water distribution loop 515 to cool the lab water as needed to maintain the baseline temperature. The fluid in the cooling device 535a may be a chilled glycol (e.g., propylene glycol), cold water, or another fluid capable of transferring heat from the lab water. It should be understood that no fluid is exchanged between the cooling device 535a and the CRODI water distribution loop 515. Rather, the fluids of the cooling device 535a and the CRODI water distribution loop 515 exchange heat through one or more interfaces between the cooling device 535a and the CRODI water distribution loop 515 without direct contact and / or transfer.
[0145] In some embodiments, the lab water stored in the storage tank 510 may be passively cooled and maintained at a baseline temperature, for example, at or near 25° C. Thus, the chiller 535a may not be running all the time. In some embodiments, the chiller 535a is activated when a large volume of lab water is produced to cool the fresh lab water to the baseline temperature. In some embodiments, the CRODI water distribution loop 515 is configured to maintain the lab water at a temperature different from the temperature of the water in the storage tank 510.
[0146] The cooling system 535a may include components for controlling the movement and / or monitoring the fluid. For example, the cooling system 535a may include one or more pumps, valves (e.g., two-way valves), power sources, sensors, and / or electrical circuitry. In some embodiments, the cooling system 535a may include a compressor, an evaporator, and / or a condenser. Additional manners of maintaining temperature within the distribution loop are contemplated as would be apparent to one of ordinary skill in the art.
[0147] In some embodiments, multiple cooling devices 535 may be operatively connected to the CRODI water distribution loop 515 to provide more consistent and / or more accurate temperature control. Additionally, although cooling device 535a is depicted proximate the beginning of the CRODI water distribution loop 515, it should be understood that cooling device 535a may join the CRODI water distribution loop 515 at any point along the loop.
[0148] In some embodiments, the HRODI water distribution loop 520 may be in fluid communication with the storage tank 510 at a first end of the HRODI water distribution loop 520 and configured to receive lab water from the storage tank 510. According to further embodiments, the HRODI water distribution loop 520 may also be in fluid communication with the CRODI water distribution loop 515 via the storage tank 510 and one or more valves. In some embodiments, the HRODI water distribution loop 520 is configured to maintain the lab water in the distribution loop at a set point temperature that is different from the baseline temperature of the storage tank 510 and / or the CRODI water distribution loop 515. For example, if the lab water is maintained at about 18°C to about 25°C by the storage tank 510 and the CRODI water distribution loop 515, the HRODI water distribution loop 520 may maintain the lab water between about 53°C to about 57°C. In some embodiments, the set point temperature of the HRODI water distribution loop 520 is variable and may be adjusted based on input from a user and / or parameters associated with a particular procedure.
[0149] In some embodiments, the HRODI water distribution loop 520 comprises a heat exchanger 550 configured to raise the temperature of the laboratory water received from the CRODI water distribution loop 515 to a set point temperature and maintain the water at the set point temperature. The heat exchanger 550 may be structurally and / or functionally similar to the heat exchanger 150 described in connection with FIGS. 1A and 1C. Thus, the heat exchanger 550 may circulate a heated fluid (e.g., steam or heated water) through the heat exchanger 550 in proximity to the HRODI water distribution loop 520 to continuously heat the laboratory water and maintain a set point temperature, e.g., about 57° C. In some embodiments, the heat exchanger 550 may include or be in fluid communication with a boiler for receiving the heated fluid, e.g., steam. It should be understood that no fluid is exchanged between the heat exchanger 550 and the HRODI water distribution loop 520. Rather, the fluids in heat exchanger 550 and HRODI water distribution loop 520 exchange heat through one or more interfaces between heat exchanger 550 and HRODI water distribution loop 520 without direct contact and / or transfer. In some embodiments, heat exchanger 550 may be configured as a closed recirculation system. In some embodiments, heat exchanger 550 may be configured as an open recirculation system. Various types of heating units and configurations thereof may be implemented herein as would be known to one of ordinary skill in the art.
[0150] The heat exchanger 550 may include additional components for controlling and / or monitoring the heating fluid. For example, the heat exchanger 550 may include one or more pumps, valves (e.g., two-way valves), power sources, sensors, and / or electrical circuitry.
[0151] In some embodiments, multiple heat exchangers 550 may be operatively connected to the HRODI water distribution loop 520 to provide more consistent and / or more accurate temperature control. Additionally, although the heat exchanger 550 is depicted proximate an end portion of the HRODI water distribution loop 520, it should be understood that the heat exchanger 550 may join the HRODI water distribution loop 520 at any point along the loop.
[0152] In some embodiments, the HRODI water distribution loop 520 may include an optional chiller 535b configured to reduce the temperature of the lab water in the HRODI water distribution loop 520 to another set point temperature (e.g., a baseline temperature) before returning the lab water to the storage tank 510. The chiller 535b may be structurally and / or functionally similar to the chiller 535a described in connection with the CRODI water distribution loop 515 and the chiller 135 described in connection with FIGS. 1A and 1B. Thus, the chiller 535b may circulate a fluid through the chiller 535b in close proximity to the HRODI water distribution loop 520 to cool the lab water and reduce the temperature of the lab water, as needed. The fluid in the chiller 535b may be chilled glycol (e.g., propylene glycol), cold water, or another fluid capable of transferring heat from the lab water. It should be understood that no fluid is exchanged between the chiller 535b and the HRODI water distribution loop 520. Rather, the fluids in the cooling device 535b and the HRODI water distribution loop 520 exchange heat through one or more interfaces between the cooling device 535b and the HRODI water distribution loop 520 without direct contact and / or transfer.
[0153] The cooling device 535b may include components for controlling movement and / or monitoring the fluid. For example, the cooling device 535b may include one or more pumps, valves (e.g., bidirectional valves), power sources, sensors, and / or electrical circuitry. In some embodiments, the cooling device 535b may include a compressor, an evaporator, and / or a condenser. Additional manners of reducing the temperature of the laboratory water in the HRODI water distribution loop 620 are contemplated as would be apparent to one of ordinary skill in the art. Furthermore, although the cooling device 535b is depicted near an end portion of the HRODI water distribution loop 520, it should be understood that the cooling device 535b may join the HRODI water distribution loop 520 at any point along the loop.
[0154] It should be understood that the elevated temperature in the HRODI water distribution loop 520 is an optional feature that can be activated and deactivated. Thus, for a particular period of time, the lab water in the HRODI water distribution loop 520 may not be elevated. In some embodiments, the HRODI water distribution loop 520 may have a baseline temperature that substantially matches the CRODI water distribution loop 515 and / or the storage tank 510. For example, the temperature of the lab water in the HRODI water distribution loop 520 may be an ambient temperature as described herein.
[0155] In some embodiments, the HRODI water distribution loop 520 may return lab water to the storage tank 510 to recycle lab water not used at the set point temperature. In some embodiments, the HRODI water distribution loop 520 may be in fluid communication with the CRODI water distribution loop 515 via the storage tank 510. In some embodiments, as shown in FIG. 5, the HRODI water distribution loop 520 may be in direct fluid communication with the storage tank 510 and may return water directly to the storage tank 510. In some embodiments, the heat exchanger 550 and / or additional heat exchangers or chillers (e.g., chiller 535b) of the HRODI water distribution loop 520 may cool the lab water in the HRODI water distribution loop 520 back to a baseline temperature before discharging to the storage tank 510. In further embodiments, the HRODI water distribution loop 520 may allow for passive cooling of the lab water to a baseline temperature in the HRODI water distribution loop 520 before transferring the water to the storage tank 510. Additional ways of reducing the temperature of the laboratory water in the HRODI water distribution loop 520 are contemplated as would be apparent to one of ordinary skill in the art.
[0156] By returning heated laboratory water from the HRODI water distribution loop 520 to the storage tank 510, laboratory water is conserved and waste is minimized. Typically, production of highly purified laboratory water is expensive, time consuming, and energy intensive due to the equipment, consumables, and precision required. Optionally, costs may be significantly reduced by recycling heated laboratory water from the HRODI water distribution loop 520 as described herein. With systems and methods as described, immediate availability of water and efficient use of water may be achieved simultaneously.
[0157] In some embodiments, CRODI water distribution loop 515 and HRODI water distribution loop 520 may be selectively in communication with storage tank 510 via one or more omni-directional or bi-directional valves (not shown). Thus, after laboratory water is transferred between CRODI water distribution loop 515, HRODI water distribution loop 520, and storage tank 510, the laboratory water in each distribution loop of HRODI water distribution loop 520 and CRODI water distribution loop 515 may be separated by closing one or more valves to maintain the water in each water distribution loop at its respective separate set point temperature. For example, water in HRODI water distribution loop 520 may circulate within HRODI water distribution loop 520 while one or more valves are closed. As water is consumed from HRODI water distribution loop 520, one or more valves may be opened to replenish the water supply from storage tank 510 (e.g., via valve 530d). Once use of the water at the set point temperature in a given example is complete, a valve may be opened to return the water to the storage tank 510 (eg, via valve 530c).
[0158] The CRODI Water and HRODI Water distribution loop systems can be operated manually, manually and automatically, and fully automatically. For automatic operation, computer processors and electronically controlled valves and heat exchangers can be employed. Exemplary approaches for automatic control using computer techniques are provided herein.
[0159] In some embodiments, the valve 130 is in electrical communication with the processor and may be controlled by the processor via electrical signals, as further described herein. In some embodiments, the valve 130 is operably connected to an actuator to open and close the valve. In some embodiments, the valve 130 may be a bi-directional valve. In some embodiments, the valve 130 may be a zero static tee valve. In some embodiments, the valve 130 may be a solenoid valve. In some embodiments, the valve 130 may be a servo motor operably connected to open and close the valve. Additional types of valves are contemplated herein as would be apparent to one of ordinary skill in the art.
[0160] CRODI water distribution loop 515 and HRODI water distribution loop 520 may each form a complete loop in a "chase the tail" configuration to allow circulation within each loop. In an additional embodiment, as shown in FIG. 5, inflow and outflow to and from each distribution loop of CRODI water distribution loop 515 and HRODI water distribution loop 520 may occur through separate connecting channels. For example, inflow from storage tank 510 to CRODI water distribution loop 515 and HRODI water distribution loop 520 may occur through respective valves 530a and 530d, and outflow from CRODI water distribution loop 515 and HRODI water distribution loop 520 to storage tank 510 may occur through respective valves 530b and 530c.
[0161] The CRODI water distribution loop 515 and the HRODI water distribution loop 520 may further include one or more outlets 525 for dispensing laboratory water. The outlets 525 may be provided throughout various dedicated spaces within the facility. In some embodiments, the outlets 525 for each of the distribution loops 515 and 520 are intended for unique purposes. For example, the cold or ambient water in the CRODI water distribution loop 515 may be sufficient for cleaning, rinsing, and chemical and / or biotechnology processes. However, heated water at a precisely controlled temperature may be required for media preparation, buffer preparation, etc., and may be provided by an outlet 525 in communication with the HRODI water distribution loop 520.
[0162] In some embodiments, at least some of the outlets 525 may be manual outlets that can be manually operated by a user, such as a faucet, a sink, a wall mounted drain, a media / buffer outlet, etc. In some embodiments, at least some of the outlets 525 may be automatic outlets that connect a supply of laboratory water to equipment such as refrigerators, washing equipment for glassware and other lab supplies, incubators, and / or autoclave machines. It should be understood that any type of outlet 525 may be configured as manual or automatic according to function or preference.
[0163] In some embodiments, CRODI water distribution loop 515 may include one or more pumps dedicated to circulating water in CRODI water distribution loop 515. In some embodiments, HRODI water distribution loop 520 may include one or more pumps dedicated to circulating water in HRODI water distribution loop 520. For example, as shown in FIG. 5, water may circulate independently in each distribution loop while one or more valves (e.g., valves 530a-530d) between CRODI water distribution loop 515 and HRODI water distribution loop 520 are closed. Thus, each of CRODI water distribution loop 515 and HRODI water distribution loop 520 may have one or more dedicated pumps so that water may circulate in the distribution loops even when isolated from each other. According to another embodiment, water may circulate through both distribution loops, for example, via storage tank 510, while one or more valves (e.g., valves 530a-530d) between CRODI water distribution loop 515 and HRODI water distribution loop 520 are open. Thus, CRODI water distribution loop 515 and HRODI water distribution loop 520 may share one or more pumps such that when not isolated from one another, water may circulate through CRODI water distribution loop 515 and HRODI water distribution loop 520. In some embodiments, one or more pumps of CRODI water distribution loop 515 and HRODI water distribution loop 520 are centrifugal pumps. However, additional types of pumps may be utilized herein as would be apparent to one of ordinary skill in the art.
[0164] Piping forming CRODI water distribution loop 515, HRODI water distribution loop 520, outlet 525, and / or additional piping in system 500 may comprise carbon steel piping and fittings. In some embodiments, the piping may be insulated with, for example, fiberglass insulation and / or a jacket to efficiently maintain the temperature of the water in the piping. In some embodiments, the jacket may be a PVC jacket (e.g., for indoor piping) or an aluminum jacket (e.g., for outdoor piping).
[0165] In some embodiments, the CRODI water distribution loop 515 and the HRODI water distribution loop 520 may be operably connected to one or more exhaust fans configured to exhaust energy from the distribution system. For example, the exhaust fans of each of the water distribution loops may operate simultaneously to exhaust heat and maintain the condition of the distribution system. In some embodiments, the exhaust fans may form an energy recovery unit including one or more coils and one or more strobe fans that may recycle energy (e.g., heat) exhausted from the distribution system for heating air within the facility and for other purposes.
[0166] Each of the laboratory water distribution loops 515 and 520 may include an array of sensors and / or alarms configured to monitor one or more parameters in the laboratory water. For example, the array of sensors may be configured to monitor temperature, conductivity, total organic carbon, dispensing pressure, and / or loop pressure. In some embodiments, a notification or alarm may sound that one or more parameters are approaching or outside of a desired range.
[0167] Each of the distribution loops 515 and 520 may be configured with sensors and electronic control components configured to regulate the laboratory water in a proportional-integral-derivative (PID) control loop. In the PID loop, sensors may be used to continuously evaluate deviations from set parameters and a control device may implement corrections to restore the set parameters with minimal delay. For example, temperature sensors may be used to monitor temperature in a substantially continuous manner and heat exchangers may be used to implement corrections as necessary to maintain a baseline and / or set point temperature for each distribution loop.
[0168] It should be understood that any of the various valves described herein with respect to components of system 500 may comprise any type of valve that would be known to one of ordinary skill in the art. For example, the valves may comprise bidirectional valves, zero static tee valves, solenoid valves, servo motor controlled valves, etc.
[0169] In some embodiments, any of the disclosed features or components may be provided redundantly for any of the purposes described herein and utilized to achieve more consistent conditions and / or reduce the probability of failure. For example, heat exchangers, fans, distribution pumps, sensors, etc. may be provided in duplicate or triplicate for any of the purposes described herein.
[0170] Control system and control method The laboratory water distribution loop system 500 described herein may be controlled via a process control system. In some embodiments, the process control system comprises one or more processors and a non-transitory computer readable medium storing instructions executable by the one or more processors. In some embodiments, the process control system comprises one or more programmable logic controllers (PLCs).
[0171] The process control system may further include one or more interface units, or operator interface terminals (OIT) 565, for a user or operator to interface with the system 500, including receiving information and / or providing input. In some embodiments, the OIT 565 may be locally connected to the equipment skid, for example, mounted on a NEMA 4 control panel on the equipment skid. In some embodiments, the OIT 565 may be remotely located and connected to the laboratory water distribution loop system 500 via a wired or wireless connection, as would be readily known to one of ordinary skill in the art. In some embodiments, the OIT 565 may be embodied as a software application on a mobile device, such as a tablet or cell phone.
[0172] In some embodiments, the OIT 565 includes a display and input devices, such as a touch screen, keyboard, and / or keypad. In some embodiments, the OIT 565 may be used to provide operator monitoring and control of the equipment. In some embodiments, the OIT 565 may be used to set temperatures within sections of the laboratory water distribution loop system 500. In some embodiments, the OIT may be used to view system status, alerts, notifications, alarms, etc.
[0173] The OIT 565 may additionally include various components to perform the various functions described herein, as would be apparent to one of ordinary skill in the art, including, but not limited to, transmitters, solenoids, analyzers, power sources, sensors, and electrical circuitry, as well as emergency controls.
[0174] Laboratory Water Distribution Loop System 600 Referring now to FIG. 6, an exemplary laboratory water distribution loop system 600 is depicted according to an embodiment. As shown in FIG. 6, the laboratory water distribution loop system 600 includes a laboratory water generation skid 605, a storage tank 610 in fluid communication with the laboratory water generation skid 605, a first CRODI water distribution loop 615a and a second CRODI water distribution loop 615b (collectively, CRODI water distribution loops 615) in fluid communication with the storage tank 610, and a HRODI water distribution loop 620 in fluid communication with the storage tank 610. According to some embodiments of the present disclosure, the system 600 may also include one or more additional HRODI water distribution loops 620 in fluid communication with the storage tank 610. It should be understood that the first CRODI water distribution loop 615a and the second CRODI water distribution loop 615b may be structurally and functionally similar to each other. Thus, unless otherwise noted, the first CRODI water distribution loop 615a and the second CRODI water distribution loop 615b are referred to together herein. The system further includes one or more outlets 625, each outlet 625 connected to one of the CRODI water distribution loops 615 and the HRODI water distribution loop 620 for discharging laboratory water from that distribution loop. The CRODI water distribution loop 615 and the HRODI water distribution loop 620 may be in selective communication with the storage tank 610 via one or more valves 630 (e.g., valves 630a-630f). As shown, each of the CRODI water distribution loops 615 may include a chiller 635 (e.g., chillers 635a and 635b) configured to maintain the laboratory water at a first (e.g., baseline) set point temperature. Similarly, HRODI water distribution loop 620 may include a heat exchanger 650 configured to increase the temperature of the lab water received from storage tank 610 to a second (e.g., elevated) setpoint temperature and maintain the water at the second setpoint temperature. According to some embodiments of the present disclosure, HRODI water distribution loop 620 may include an optional chiller 635c, shown in dashed lines, configured to reduce the temperature of the lab water in HRODI water distribution loop 620 to another setpoint temperature (e.g., a baseline temperature) before returning the lab water to storage tank 610.The system 600 further comprises one or more interface units, or operator interface terminals (OITs) 665, for a user or operator to interface with the system 600, including receiving information and / or providing input for control of the system.
[0175] Water Generation Skid The water generation skid 605 may include a water source for receiving potable water or other water that may be treated into laboratory water. Various processing steps may be used to generate laboratory water that preferably meets ASTM Type II standards. For example, potable water may be filtered by various media, softened, dechlorinated, deionized, distilled, and / or sterilized by the water generation skid 605. Thus, the water generation skid 605 may include various processing components.
[0176] In some embodiments, the water generating skid 605 includes a multi-media filter stage for removing particulate matter from the water. In some embodiments, the multi-media filter may be configured to remove particles having a size or diameter of 10 μm or greater. In some embodiments, the multi-media filter may be configured to remove particles having a size or diameter of 5 μm or greater. The multi-media filter may include multiple stages or layers to progressively remove particles of progressively smaller sizes. For example, the multi-media filter may include one or more gravel layers, one or more garnet layers, one or more anthracite layers, one or more coarse sand layers, one or more fine sand layers, and / or combinations thereof. In some embodiments, the media layers may be pre-backwashed and drained. In some embodiments, each media layer may be arranged and selected for specific gravity in a manner that allows for self-contained re-stratification after backwashing. For example, the media layers may be arranged by specific gravity in ascending order from top to bottom.
[0177] In some embodiments, the water generating skid 605 comprises a water softener stage configured to remove hardness ions from the water. In some embodiments, the water softener is configured to remove calcium ions (Ca2+), magnesium ions (Mg2+), and / or other metal ions from the water. In some embodiments, the water softener is configured to remove calcium and magnesium ions through ion exchange. For example, the water may be passed through a filter bed comprising resin beads (e.g., beads comprising NaCO2 particles), whereby Ca2+ and Mg2+ cations bind to the beads (e.g., COO- anions) and release sodium cations (Na+) into the water. In some embodiments, the water generating skid 605 may further comprise a brine tank and an eductor in communication with the water softener and configured to regenerate the water softener, for example, to maintain a level of NaCO2 particles to continuously remove Ca2+ and Mg2+ cations from the feedwater. In additional embodiments, the water softener may be configured to treat water with hydrated lime, e.g., Ca(OH)2, and soda ash, e.g., Na2CO3, to precipitate calcium as CaCO3 and magnesium as Mg(OH)2.
[0178] In some embodiments, the water generating skid 605 includes a carbon bed filter stage. In some embodiments, the carbon bed filter is configured to remove chlorine and other trace organic compounds from the water. In some embodiments, the carbon bed filter is configured to break down chloramines (e.g., NH2Cl, NHCl2, NCl3) in the water into chlorine, ammonia, and / or ammonium.
[0179] In some embodiments, the water generation skid 605 comprises one or more mixed deionization (DI) beds configured to remove dissolved ammonia, CO2, and / or trace charged compounds and elements.
[0180] In some embodiments, the water generating skid 605 includes additional types of ion exchange beds to remove organic compounds, as would be apparent to one of ordinary skill in the art. The ion exchange beds may include resin beads of various sizes and characteristics to remove different types of particles. For example, the ion exchange beds may include strong acid cation exchange resins, weak acid cation exchange resins, strong base anion exchange resins, weak base anion exchange resins, and / or chelating resins.
[0181] In some embodiments, the water production skid 605 includes a reverse osmosis filtration stage configured to remove trace compounds, ammonium, carbon particulates and / or other particulate matter, microorganisms, and / or endotoxins from the water. For example, the reverse osmosis stage may include a semi-permeable membrane and a pump configured to apply a pressure in the water that is greater than the osmotic pressure to cause diffusion of the water through the membrane. Because the effectiveness of reverse osmosis depends on pressure, solute concentration, and other conditions, the reverse osmosis filtration stage may include one or more sensors configured to monitor conditions within the reverse osmosis unit. For example, the reverse osmosis filtration stage may include an inlet conductivity monitor, a permeate conductivity monitor, a concentrate flow meter, a permeate flow meter, a suction pressure indicator, a high pressure kill switch, and / or an instrument air pressure switch.
[0182] In some embodiments, the water generating skid 605 includes an ultraviolet (UV) light stage configured to deactivate microorganisms in the water. For example, the water generating skid 605 may include one or more UV light sources configured to emit UV light at wavelengths of 185 nm, 254 nm, 265 nm, and / or additional wavelengths configured to deactivate microorganisms. In some embodiments, the UV light source may include a quartz lamp sleeve over the UV light source to insulate the UV light source from temperature changes. In some embodiments, the UV light stage is configured to emit light at a dose of microwatt-seconds per square centimeter (μW-s / cm2) capable of deactivating microorganisms throughout the entire volume of water within the UV light stage. The dose of light emitted within the UV light stage may be based on the internal volume, the light intensity of the one or more UV light sources, and the flow rate of water through the UV light stage. In some embodiments, the UV light stage may include an internal baffle (e.g., a helical baffle or a static blender) to facilitate thorough mixing of the water through the UV light stage, thereby causing further exposure of the water to UV light.
[0183] In some embodiments, the water generation skid 605 includes one or more filter cartridges for removing contaminants from drinking water. For example, one or more of the various stages of the water generation skid 605 described herein may be provided in the form of a cartridge.
[0184] In some embodiments, the water generation skid 605 includes additional components that would be apparent to one of ordinary skill in the art for controlling, maintaining, and regulating the flow of water through the various stages and treating the water in the manner described herein. For example, the water generation skid 605 may include distribution pumps, booster pumps, centrifugal pumps, transmitters, valves, power sources, sensors, and electrical circuitry required to treat the water and maintain the proper conditions in the various stages of the water generation skid 605.
[0185] Water Storage Tank Referring again to FIG. 6 , the water generation skid 605 is in fluid communication with a storage tank 610 configured to receive laboratory water from the water generation skid 605 and store the water therein. In some embodiments, the storage tank 610 is configured to maintain the quality of the laboratory water after processing by the water generation skid 605. Additionally, the storage tank 610 may be configured to distribute the water to a distribution loop as further described herein. The storage tank 610 may also be in fluid communication with piping and outlets that are not part of the CRODI water distribution loop 615 and the HRODI water distribution loop 620. As shown, the storage tank 610 may include one or more valves 630 for selectively allowing the flow of water between the storage tank 610 and one or more of the CRODI water distribution loop 615 (e.g., valves 630a-630d) and the HRODI water distribution loop 620 (e.g., valves 630e and 630f).
[0186] In some embodiments, the lab water received by the storage tank 610 from the water generation skid 605 may have its temperature elevated. For example, various filtration and processing steps described herein may result in lab water having an elevated temperature. Thus, the water in the storage tank 610 may be passively cooled to ambient temperature over time, actively cooled using a chiller as it enters the CRODI water distribution loop 615, or actively heated to maintain or even increase the temperature of the water using a heat exchanger as it enters the HRODI water distribution loop 620, as further described herein. In some embodiments, the storage tank 610 may include one or more of a chiller and a heat exchanger to actively cool and / or heat the lab water.
[0187] CRODI Water Distribution Loop and HRODI Water Distribution Loop 6, the CRODI water distribution loops 615 are in fluid communication with the storage tank 610. Each of the CRODI water distribution loops 615 may be configured to receive lab water from the storage tank 610 at a first end and circulate the water through the CRODI water distribution loops 615. In some embodiments, each of the CRODI water distribution loops 615 may further be in fluid communication with the storage tank 610 at a second end. The CRODI water distribution loops 615 may be configured to return the lab water to the storage tank 610 after circulating and / or distributing the lab water through the CRODI water distribution loops 615.
[0188] In some embodiments, the CRODI water distribution loop 615 is configured to maintain the laboratory water in the distribution loop at a baseline temperature. For example, the baseline temperature can be about room temperature. In another example, the baseline temperature can be between about 18° C. and about 25° C. In a further example, the baseline temperature can be less than room temperature, for example, between about 18° C. and about 22° C.
[0189] In some embodiments, each of the CRODI water distribution loops 615 includes a cooling device 635 configured to maintain the lab water at a baseline temperature. In some embodiments, the CRODI water distribution loops 615 may be in communication with one or more shared cooling devices 635 configured to maintain the lab water at a baseline temperature. The cooling devices 635 of the CRODI water distribution loops 615 may be structurally and / or functionally similar to the cooling device 135 described in connection with FIGS. 1A and 1B. Thus, the cooling devices 635 may circulate fluid through the cooling devices 635 in proximity to each CRODI water distribution loop 615 to cool the lab water as needed to maintain the baseline temperature. The fluid in the cooling devices 635 may be chilled glycol (e.g., propylene glycol), chilled water, or another fluid capable of transferring heat from the lab water. It should be understood that no fluid is exchanged between the cooling devices 635 and the CRODI water distribution loops 615. Rather, the fluids in the cooling device 635 and the CRODI water distribution loop 615 exchange heat through one or more interfaces between the cooling device 635 and the CRODI water distribution loop 615 without direct contact and / or transfer.
[0190] In some embodiments, the lab water stored in the storage tank 610 may be passively cooled and maintained at a baseline temperature, e.g., 25°C. Thus, the chiller 635 of the CRODI water distribution loop 615 may not be running all the time. In some embodiments, the chiller 635 is activated when a large volume of lab water is produced and transferred to one or both of the CRODI water distribution loops 615 to cool the fresh lab water to the baseline temperature. In some embodiments, the CRODI water distribution loop 615 is configured to maintain the lab water at a temperature different from the temperature of the water in the storage tank 610.
[0191] The cooling system 635 of the CRODI water distribution loop 615 may include components for controlling the movement and / or monitoring the fluid. For example, the cooling system 635 may include one or more pumps, valves (e.g., two-way valves), power sources, sensors, and / or electrical circuitry. In some embodiments, the cooling system 635 may include a compressor, an evaporator, and / or a condenser. Additional manners of maintaining temperature within the distribution loop are contemplated as would be apparent to one of ordinary skill in the art.
[0192] In some embodiments, multiple cooling devices 635 may be operatively connected to each of the CRODI water distribution loops 615 to provide more consistent and / or more accurate temperature control. Additionally, although the cooling devices 635 are depicted proximate the beginning of each CRODI water distribution loop 615, it should be understood that the cooling devices 635 may join the CRODI water distribution loops 615 at any point along the loop.
[0193] In some embodiments, the HRODI water distribution loop 620 may be in fluid communication with the storage tank 610 at a first end of the HRODI water distribution loop 620 and configured to receive lab water from the storage tank 610. According to further embodiments, the HRODI water distribution loop 620 may also be in fluid communication with one or more of the CRODI water distribution loops 615 via the storage tank 610 and one or more valves. In some embodiments, the HRODI water distribution loop 620 is configured to maintain the lab water in the HRODI water distribution loop 620 at a set point temperature that is different from the baseline temperature of the storage tank 610 and / or the CRODI water distribution loop 615. For example, if the lab water is maintained at about 18°C to about 25°C by the storage tank 610 and the CRODI water distribution loop 615, the HRODI water distribution loop 620 may maintain the lab water at about 53°C to about 57°C. In some embodiments, the set point temperature of the HRODI water distribution loop 620 is variable and can be adjusted based on input from a user and / or parameters associated with a particular procedure.
[0194] In some embodiments, the HRODI water distribution loop 620 comprises a heat exchanger 650 configured to raise the temperature of the laboratory water received from the storage tank 610 to a set point temperature and maintain the water at the set point temperature. The heat exchanger 650 may be structurally and / or functionally similar to the heat exchanger 150 described in connection with FIGS. 1A and 1C. Thus, the heat exchanger 650 may circulate a heated fluid (e.g., steam or heated water) through the heat exchanger 650 in proximity to the HRODI water distribution loop 620 to continuously heat the laboratory water and maintain a set point temperature, e.g., about 57° C. In some embodiments, the heat exchanger 650 may include or be in fluid communication with a boiler for receiving the heated fluid, e.g., steam. It should be understood that no fluid is exchanged between the heat exchanger 650 and the HRODI water distribution loop 620. Rather, the fluids in heat exchanger 650 and HRODI water distribution loop 620 exchange heat through one or more interfaces between heat exchanger 650 and HRODI water distribution loop 620 without direct contact and / or transfer. In some embodiments, heat exchanger 650 may be configured as a closed recirculation system. In some embodiments, heat exchanger 650 may be configured as an open recirculation system. Various types of heating units and configurations thereof may be implemented herein as would be known to one of ordinary skill in the art.
[0195] The heat exchanger 650 may include additional components for controlling and / or monitoring the heating fluid. For example, the heat exchanger 650 may include one or more pumps, valves (e.g., two-way valves), power sources, sensors, and / or electrical circuitry.
[0196] In some embodiments, multiple heat exchangers 650 may be operatively connected to the HRODI water distribution loop 620 to provide more consistent and / or more accurate temperature control. Additionally, although the heat exchanger 650 is depicted proximate an end portion of the HRODI water distribution loop 620, it should be understood that the heat exchanger 650 may join the HRODI water distribution loop 620 at any point along the loop.
[0197] In some embodiments, the HRODI water distribution loop 620 may include an optional chiller 635c configured to reduce the temperature of the lab water in the HRODI water distribution loop 620 to another set point temperature (e.g., a baseline temperature) before returning the lab water to the storage tank 610. The chiller 635c may be structurally and / or functionally similar to the chillers 635a and 635b described in connection with the CRODI water distribution loop 615 and the chiller 135 described in connection with FIGS. 1A and 1B. Thus, the chiller 635c may circulate a fluid through the chiller 635c in close proximity to the HRODI water distribution loop 620 to cool the lab water and reduce the temperature of the lab water, as needed. The fluid in the chiller 635c may be chilled glycol (e.g., propylene glycol), cold water, or another fluid capable of transferring heat from the lab water. It should be understood that no fluid is exchanged between the cooling device 635c and the HRODI water distribution loop 620. Rather, the fluids in the cooling device 635c and the HRODI water distribution loop 620 exchange heat through one or more interfaces between the cooling device 635c and the HRODI water distribution loop 620 without direct contact and / or transfer.
[0198] The cooling device 635c may include components for controlling movement and / or monitoring the fluid. For example, the cooling device 635c may include one or more pumps, valves (e.g., bidirectional valves), power sources, sensors, and / or electrical circuitry. In some embodiments, the cooling device 635c may include a compressor, an evaporator, and / or a condenser. Additional methods of reducing the temperature of the laboratory water in the distribution loop are contemplated as would be apparent to one of ordinary skill in the art. Furthermore, although the cooling device 635c is depicted near an end portion of the HRODI water distribution loop 620, it should be understood that the cooling device 635c may join the HRODI water distribution loop 620 at any point along the loop.
[0199] It should be understood that the elevated temperature in the HRODI water distribution loop 620 is an optional feature that can be activated and deactivated. Thus, for a particular period of time, the lab water in the HRODI water distribution loop 620 may not be elevated. In some embodiments, the HRODI water distribution loop 620 may have a baseline temperature that substantially matches the CRODI water distribution loop 615 and / or the storage tank 610. For example, the temperature of the lab water in the HRODI water distribution loop 620 may be an ambient temperature as described herein.
[0200] In some embodiments, the HRODI water distribution loop 620 may return lab water to the storage tank 610 to recycle lab water not used at the elevated set point temperature. In some embodiments, the HRODI water distribution loop 620 may be in fluid communication with one or more of the CRODI water distribution loops 615 via the storage tank 610. In some embodiments, as shown in FIG. 6, the HRODI water distribution loop 620 may be in direct fluid communication with the storage tank 610 and may return water directly to the storage tank 610. In some embodiments, the heat exchanger 650 and / or additional heat exchangers or chillers of the HRODI water distribution loop 620 may cool the lab water in the HRODI water distribution loop 620 back to a baseline temperature before transferring the water to the storage tank 610. In further embodiments, the HRODI water distribution loop 620 may allow for passive cooling of the lab water to a baseline temperature in the HRODI water distribution loop 620 before transferring the water to the storage tank 610. Additional ways of reducing the temperature within the HRODI water distribution loop 620 are contemplated as would be apparent to one of ordinary skill in the art.
[0201] By returning heated laboratory water from the HRODI water distribution loop 620 to the storage tank 610, laboratory water is conserved and waste is minimized. Typically, production of highly purified laboratory water is expensive, time consuming, and energy intensive due to the equipment, consumables, and precision required. Optionally, costs may be significantly reduced by recycling heated laboratory water from the HRODI water distribution loop 620 as described herein. With systems and methods as described, immediate availability of water and efficient use of water may be achieved simultaneously.
[0202] In some embodiments, one or more of the CRODI water distribution loop 615 and the HRODI water distribution loop 620 may be selectively in communication with the storage tank 610 through one or more omni-directional or bidirectional valves. For example, one or more valves may be positioned in a channel connecting the HRODI water distribution loop 620 to one or more of the CRODI water distribution loops 615. Thus, after the laboratory water is transferred between the storage tank 610, the CRODI water distribution loop 615, and the HRODI water distribution loop 620, the laboratory water in each distribution loop of the HRODI water distribution loop 620 and the CRODI water distribution loop 615 may be separated by closing one or more valves to maintain the water in each water distribution loop at its respective separate set point temperature. For example, the water in the HRODI water distribution loop 620 may circulate in the HRODI water distribution loop 620 while one or more valves are closed. As water is consumed from the HRODI water distribution loop 620, one or more valves may be opened (e.g., via valve 630f) to replenish the water supply from the storage tank 610. When use of the water at the setpoint temperature in a given example is completed, a valve may be opened (e.g., via valve 630e) to return the water to the storage tank 610.
[0203] The CRODI water and HRODI water distribution loop systems can be operated manually, manually and automatically, and fully automatically. For automatic operation, a computer processor and electronically controlled valves and heat exchangers can be employed. An exemplary approach for automatic control using computer techniques is provided herein.
[0204] In some embodiments, the valve 630 is in electrical communication with the processor and may be controlled by the processor via electrical signals, as further described herein. In some embodiments, the valve 630 is operably connected to an actuator to open and close the valve. In some embodiments, the valve 630 may be a bi-directional valve. In some embodiments, the valve 630 may be a zero static tee valve. In some embodiments, the valve 630 may be a solenoid valve. In some embodiments, the valve 630 may be a servo motor operably connected to open and close the valve. Additional types of valves are contemplated herein as would be apparent to one of ordinary skill in the art.
[0205] CRODI water distribution loop 615 and HRODI water distribution loop 620 may each form a complete loop in a "chase the tail" configuration to allow circulation within each loop. As shown in FIG. 6, inflow and outflow to and from each distribution loop of CRODI water distribution loop 615 and HRODI water distribution loop 620 may occur through separate connecting channels. For example, inflow from storage tank 610 to CRODI water distribution loop 615a, CRODI water distribution loop 615b, and HRODI water distribution loop 620 may occur through respective valves 630a, 630c, and 630f, and outflow from CRODI water distribution loop 615a, CRODI water distribution loop 615b, and HRODI water distribution loop 620 to storage tank 610 may occur through respective valves 630b, 630d, and 630e.
[0206] The CRODI water distribution loop 615 and the HRODI water distribution loop 620 may further include one or more outlets 625 for dispensing laboratory water. The outlets 625 may be provided throughout various dedicated spaces within the facility. In some embodiments, the outlets 625 for each of the distribution loops 615 and 620 are intended for unique purposes. For example, the cold or ambient water in the CRODI water distribution loop 615 may be sufficient for cleaning, rinsing, and chemical and / or biotechnology processes. However, heated water at a precisely controlled temperature may be required for media preparation, buffer preparation, etc., and may be provided by an outlet 625 in communication with the HRODI water distribution loop 620.
[0207] In some embodiments, at least some of the outlets 625 may be manual outlets that can be manually operated by a user, such as a faucet, a sink, a wall mounted drain, a media / buffer outlet, etc. In some embodiments, at least some of the outlets 625 may be automatic outlets that connect a supply of laboratory water to equipment such as refrigerators, washing equipment for glassware and other lab supplies, incubators, and / or autoclave machines. It should be understood that any type of outlet 625 may be configured as manual or automatic according to function or preference.
[0208] In some embodiments, CRODI water distribution loop 615 may include one or more pumps dedicated to circulating water within CRODI water distribution loop 615. In some embodiments, HRODI water distribution loop 620 may include one or more pumps dedicated to circulating water within HRODI water distribution loop 620. For example, as shown in FIG. 6, water may circulate independently within each of CRODI water distribution loop 615 and HRODI water distribution loop 620 while one or more valves (e.g., valves 630a-630f) between CRODI water distribution loop 615 and HRODI water distribution loop 620 are closed. Thus, each of CRODI water distribution loop 615 and HRODI water distribution loop 620 may have one or more dedicated pumps such that water may circulate within that distribution loop even when isolated from the other water distribution loop. According to another embodiment, water may be circulated through one or more of the CRODI water distribution loop 615 and the HRODI water distribution loop 620 via the storage tank 610 while one or more valves (e.g., valves 630a-630f) between the CRODI water distribution loop 615 and the HRODI water distribution loop 620 and, for example, the storage tank 610 are open. Thus, one or more of the CRODI water distribution loop 615 and the HRODI water distribution loop 620 may share one or more pumps such that water may be circulated through the distribution loops when not isolated from one another. In some embodiments, the pumps of one or more of the CRODI water distribution loop 615 and the HRODI water distribution loop 620 are centrifugal pumps. However, additional types of pumps may be utilized herein as would be apparent to one of ordinary skill in the art.
[0209] The piping forming the CRODI water distribution loop 615, the HRODI water distribution loop 620, the outlet 625, and / or additional piping in the system 600 may include carbon steel piping and fittings. In some embodiments, the piping may be insulated with, for example, fiberglass insulation and / or a jacket to efficiently maintain the temperature of the water in the piping. In some embodiments, the jacket may be a PVC jacket (e.g., for indoor piping) or an aluminum jacket (e.g., for outdoor piping).
[0210] In some embodiments, the CRODI water distribution loop 615 and the HRODI water distribution loop 620 may be operably connected to one or more exhaust fans configured to exhaust energy from the distribution system. For example, the exhaust fans of each of the water distribution loops may operate simultaneously to exhaust heat and maintain the condition of the distribution system. In some embodiments, the exhaust fans may form an energy recovery unit including one or more coils and one or more strobe fans that may recycle energy (e.g., heat) exhausted from the distribution system for heating air within the facility and for other purposes.
[0211] Each of the laboratory water distribution loops 615 and 620 may include an array of sensors and / or alarms configured to monitor one or more parameters in the laboratory water. For example, the array of sensors may be configured to monitor temperature, conductivity, total organic carbon, dispensing pressure, and / or loop pressure. In some embodiments, a notification or alarm may sound that one or more parameters are approaching or outside of a desired range.
[0212] Each of the distribution loops 615 and 620 may be configured with sensors and electronic control components configured to regulate the laboratory water in a proportional-integral-derivative (PID) control loop. In the PID loop, sensors may be used to continuously evaluate deviations from set parameters and a control device may implement corrections to restore the set parameters with minimal delay. For example, temperature sensors may be used to monitor temperature in a substantially continuous manner and heat exchangers may be used to implement corrections as necessary to maintain a baseline and / or set point temperature for each distribution loop.
[0213] It should be understood that any of the various valves described herein with respect to components of system 600 may comprise any type of valve that would be known to one of ordinary skill in the art. For example, the valves may comprise bidirectional valves, zero static tee valves, solenoid valves, servo motor controlled valves, etc.
[0214] In some embodiments, any of the disclosed features or components may be provided redundantly for any of the purposes described herein and utilized to achieve more consistent conditions and / or reduce the probability of failure. For example, heat exchangers, fans, distribution pumps, sensors, etc. may be provided in duplicate or triplicate for any of the purposes described herein. Additional components such as manifolds / mixers to provide fluid communication between loops when different temperatures are desired while obviating the need to change temperature set points may also be added.
[0215] It should be understood that a high degree of specificity is required in preparing materials, especially in virus production processes. Various production processes can be highly dependent on the temperature of the water and other materials utilized, and the processes can also be time-dependent. Thus, while conventional practice may involve drawing water from a common source and heating or cooling as needed, typical equipment may not be equipped with sensors and / or feedback systems to allow fine control of temperature in the manner required. Furthermore, time-dependent production processes involving several steps may not tolerate the delays associated with conventional methods of preparing temperature-specific laboratory water. Thus, the systems disclosed herein advantageously eliminate the problems of conventional systems and methods by providing an accurate temperature-controlled water source that can be pre-set, maintained, and made available on demand. Furthermore, unused temperature-controlled water is cooled and recycled such that waste of water purified by the systems and methods herein is minimized.
[0216] Control system and control method The laboratory water distribution loop system 600 described herein may be controlled via a process control system. In some embodiments, the process control system comprises one or more processors and a non-transitory computer readable medium storing instructions executable by the one or more processors. In some embodiments, the process control system comprises one or more programmable logic controllers (PLCs).
[0217] The process control system may further include one or more interface units, or operator interface terminals (OIT) 665, for a user or operator to interface with the system 600, including receiving information and / or providing input. In some embodiments, the OIT 665 may be locally connected to the equipment skid, for example, mounted on a NEMA 4 control panel on the equipment skid. In some embodiments, the OIT 665 may be remotely located and connected to the laboratory water distribution loop system 600 via a wired or wireless connection, as would be readily known to one of ordinary skill in the art. In some embodiments, the OIT 665 may be embodied as a software application on a mobile device, such as a tablet or cell phone.
[0218] In some embodiments, the OIT 665 includes a display and input devices, such as a touch screen, keyboard, and / or keypad. In some embodiments, the OIT 665 may be used to provide operator monitoring and control of the equipment. In some embodiments, the OIT 665 may be used to set temperatures within sections of the laboratory water distribution loop system 600. In some embodiments, the OIT may be used to view system status, alerts, notifications, alarms, etc.
[0219] The OIT 665 may additionally include various components to perform the various functions described herein, as would be apparent to one of ordinary skill in the art, including, but not limited to, transmitters, solenoids, analyzers, power sources, sensors, and electrical circuitry, as well as emergency controls.
[0220] Figures 7 and 8 are flow diagrams illustrating a computer-implemented method, generally indicated at 700, for adjusting the water temperature in one or more of the laboratory water distribution loops of the water distribution systems 500 and 600 described in connection with Figures 5 and 6, respectively. In particular, Figure 7 illustrates a computer-implemented method, generally indicated at 700, for adjusting the water temperature in one or more of the HRODI water distribution loops 520 and 620 of the laboratory water distribution systems 500 and 600, and Figure 8 illustrates a computer-implemented method, generally indicated at 800, for adjusting the water temperature in one or more of the CRODI water distribution loops 515, 615a, and 615b of the laboratory water distribution systems 500 and 600.
[0221] Referring now to FIG. 7, a flow diagram of an illustrative computer-implemented method for regulating water temperature within a HRODI water distribution loop of a water distribution system (e.g., water distribution loops 520 and 620 described in connection with FIGS. 5 and 6, respectively) is depicted in accordance with an embodiment of the present disclosure. Method 700 may include receiving 710 an input related to a set point temperature of the laboratory water via an input device; optionally transferring 715 a first amount of water from a storage tank to a HRODI water distribution loop of the distribution system; heating 720 the first amount of water in the HRODI water distribution loop of the distribution system from a baseline temperature to a set point temperature; maintaining 730 the first amount of water at the set point temperature for a period of time; holding 740 a second amount of water at the baseline temperature for a period of time; cooling 750 the first amount of water from the set point temperature to the baseline temperature in response to a trigger; and optionally recycling 755 the second amount of water in the HRODI water distribution loop by transferring it to one or more of the storage tank and the CRODI water distribution loop.
[0222] In some embodiments, the distribution system may include a storage tank, one or more CRODI water distribution loops in fluid communication with the storage tank, and a HRODI water distribution loop in fluid communication with the storage tank. For example, as shown in FIG. 5, the distribution system may include a single CRODI water distribution loop, or as shown in FIG. 6, the distribution system may include multiple CRODI water distribution loops. In some embodiments, the CRODI water distribution loop may be isolated from the HRODI water distribution loop, but may be in fluid communication with the storage tank along with the HRODI water distribution loop. For example, the water distribution system may be a laboratory water distribution loop system 500 or 600, as shown in FIGS. 5 and 6. In some embodiments, the CRODI water distribution loop may be selectively in fluid communication with the HRODI water distribution loop via one or more channels and / or controllable valves extending between the CRODI water distribution loop and the HRODI water distribution loop to facilitate the transfer of laboratory water between the CRODI water distribution loop and the HRODI water distribution loop.
[0223] In some embodiments, receiving 710 an input related to a setpoint temperature may include receiving an input from a user via an OIT (e.g., OIT 565 or 665) to activate a heating cycle. In some embodiments, the input may include pressing a button to activate production of heated RODI (i.e., "HRODI") at the setpoint temperature. In some embodiments, the command selected by the user is generic (e.g., "HEAT") and does not specify a setpoint temperature. Rather, the setpoint temperature is fixed and known to the process control system. In some embodiments, the user may be able to set or input a desired setpoint temperature.
[0224] In some embodiments, the optional step 715 of transferring a first amount of water from the storage tank to the HRODI water distribution loop may include first actuating (e.g., by a processor) one or more valves from a closed position to an open position to enable transfer of water between the storage tank and the HRODI water distribution loop, and then moving the one or more valves from an open position to a closed position to isolate the storage tank from the HRODI water distribution loop. In some embodiments, the optional step 715 of transferring a first amount of water from the storage tank to the HRODI water distribution loop may include replenishing consumed water from the storage tank.
[0225] In some embodiments, the HRODI water distribution loop and the storage tank are isolated during heating step 720, maintaining step 730, holding step 740, and cooling step 750. For example, method 700 may include activating one or more valves (e.g., by a processor) to isolate the HRODI water distribution loop and the storage tank. In some embodiments, the water in the HRODI water distribution loop remains isolated until it normalizes at or near a baseline temperature.
[0226] In some embodiments, the heating step 720, maintaining step 730, holding step 740, and cooling step 750 are facilitated by one or more heat exchangers in the distribution system. For example, the distribution system may include a heat exchanger, as described in detail with respect to the laboratory water distribution loop systems 100, 500, and 600 of the present disclosure.
[0227] The cooling step 750 may be triggered in a variety of ways. In some embodiments, the trigger includes the completion of a predetermined time limit. For example, the system may have preprogrammed time limits, e.g., 15 minutes, 30 minutes, 60 minutes, more than 60 minutes, or individual values or rangers therebetween. In another example, the user may input the time limit at a particular instance. Thus, the trigger may be a notification from a timer that a period of time has reached a predetermined time limit and / or an inputted time limit. In some embodiments, the trigger includes additional input from the user related to the termination of the HRODI request. For example, the user may press a button to deactivate the HRODI (e.g., a "COOL" button). In some embodiments, the trigger includes an error or alarm, e.g., an alarm alert of an abnormal or dangerous condition in the water. For example, the error or alarm may be received from a computing device associated with the distribution system, the water in the distribution system, and / or the facility housing the distribution system (e.g., environmental conditions).
[0228] In some embodiments, the interface units (e.g., operator interface terminals 565 and 665) may provide additional functionality. In some embodiments, HRODI requests may be planned or scheduled for a particular time in the future. For example, HRODI requests may be manually scheduled for a future time based on planned activities. In some embodiments, rather than entering individual requests, HRODI requests may be planned or initiated based on a particular production process. For example, if a formalized process for producing a particular composition is planned or in progress, the process control system may be programmed based on a database of the formal production process to activate HRODI requests according to the formal production process. In some embodiments, the production process may require multiple HRODI requests at discrete time intervals. Thus, HRODI requests may be activated based on time. In some embodiments, the process control system may communicate with additional computing components and schedule or initiate HRODI requests based on information received from those computing components. Thus, HRODI requests may be initiated based on an indicated stage of the production process and / or additional information.
[0229] 8, a flow diagram of an illustrative computer-implemented method, generally designated 800, for regulating a temperature of water in one or more CRODI water distribution loops of a water distribution system (e.g., water distribution loops 515, 615a, and / or 615b discussed in connection with FIGS. 5 and 6) is depicted in accordance with an embodiment of the present disclosure. Method 800 includes receiving an input related to a baseline temperature of the water via an input device 810, optionally transferring a first quantity of water from a storage tank to one or more CRODI water distribution loops of the distribution system 815, cooling the first quantity of water in the one or more CRODI water distribution loops of the distribution system from an initial temperature to the baseline temperature 820, continuously maintaining the first quantity of water at the baseline temperature for a period of time 830, and terminating temperature control in response to a trigger 840.
[0230] In some embodiments, the distribution system may include a storage tank, one or more CRODI water distribution loops in fluid communication with the storage tank, and a HRODI water distribution loop in fluid communication with the storage tank. For example, as shown in FIG. 5, the distribution system may include a single CRODI water distribution loop, or as shown in FIG. 6, the distribution system may include multiple CRODI water distribution loops. In some embodiments, the CRODI water distribution loop may be isolated from the HRODI water distribution loop, but may be in fluid communication with the storage tank along with the HRODI water distribution loop. For example, the water distribution system may be a laboratory water distribution loop system 500 or 600, as shown in FIGS. 5 and 6. In some embodiments, the CRODI water distribution loop may be selectively in fluid communication with the HRODI water distribution loop via one or more channels and / or controllable valves extending between the CRODI water distribution loop and the HRODI water distribution loop to facilitate the transfer of laboratory water between the CRODI water distribution loop and the HRODI water distribution loop.
[0231] In some embodiments, receiving input related to the baseline temperature 810 may include receiving input from a user via the OIT to activate a cooling cycle. In some embodiments, the input may include pressing a button to activate production of cooled RODI (i.e., "CRODI") at the baseline temperature. In some embodiments, the command selected by the user is generic (e.g., "COOL") and does not specify a baseline temperature. Rather, the baseline temperature is selected and known to the process control system. In some embodiments, the user may be able to set or input a desired baseline temperature. In some embodiments, the system is configured to continuously maintain the water at the baseline temperature while the system is operating. The baseline temperature selected is typically room temperature, approximately 68°F to 76°F. Thus, the input may include activating the system, for example, an initial activation, a daily activation, or an activation from a sleep or hibernation mode.
[0232] In some embodiments, the optional step of transferring 815 a first amount of water from the storage tank to the CRODI water distribution loop may include first actuating (e.g., by a processor) one or more valves from a closed position to an open position to allow transfer of water between the storage tank and the CRODI water distribution loop, and then moving one or more valves from an open position to a closed position to isolate the storage tank from the CRODI water distribution loop. In some embodiments, the step of transferring 815 a first amount of water from the storage tank to the CRODI water distribution loop may include replenishing consumed water from the storage tank.
[0233] In some embodiments, the CRODI water distribution loop and the storage tank are isolated during the cooling step 820 and the maintaining step 830. For example, the method 800 may be performed simultaneously with the method 700 to control the temperature of the water in the HRODI water distribution loop without affecting the process 800 for maintaining the baseline temperature of the CRODI water distribution loop. One or more valves may be actuated (e.g., by a processor) to isolate one or more of the CRODI water distribution loops from the storage tank. In some embodiments, the CRODI water distribution loop remains isolated until the water in both the water distribution loop and the storage tank is normalized at or near the baseline temperature. In additional embodiments, the water in both the CRODI water distribution loop and / or the HRODI water distribution loop may be cooled and maintained at the baseline temperature by the process 800, for example, when there is no active HRODI demand.
[0234] In some embodiments, the cooling step 820 and the maintaining step 830 are facilitated by one or more chillers or heat exchangers in the distribution system. For example, the distribution system may include the chillers described in detail with respect to the laboratory water distribution loop systems 100, 500, and 600 of the present disclosure.
[0235] The termination step 840 may be triggered in various manners. In some embodiments, the trigger includes the completion of a predetermined time limit. For example, the system may have preprogrammed time limits, e.g., 15 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, 24 hours, more than 24 hours, or individual values or rangers therebetween. In another example, the user may input the time limit at a particular instance. Thus, the trigger may be a notification from a timer that a period of time has reached a predetermined time limit and / or an inputted time limit. In some embodiments, the trigger includes additional input from the user related to the termination of the CRODI request. For example, the user may press a button to deactivate CRODI (e.g., an "END" button). In some embodiments, the trigger includes an error or alarm, e.g., an alarm alert of an abnormal or dangerous condition in the water. For example, the error or alarm may be received from a computing device associated with the distribution system, the water in the distribution system, and / or the facility housing the distribution system (e.g., environmental conditions).
[0236] In some embodiments, the interface unit may provide additional functionality. In some embodiments, CRODI requests may be planned or scheduled for a particular time in the future. For example, CRODI requests may be manually scheduled for a future time based on planned activities. In some embodiments, rather than entering individual requests, CRODI requests may be planned or initiated based on a particular production process. For example, if a formalized process for producing a particular composition is planned or in progress, the process control system may be programmed based on a database of the formal production process to activate CRODI requests according to the formal production process. In some embodiments, the production process may require multiple CRODI requests at discrete time intervals. Thus, CRODI requests may be activated based on time. In some embodiments, the process control system may communicate with additional computing components and schedule or initiate CRODI requests based on information received from those computing components. Thus, CRODI requests may be initiated based on an indicated stage of the production process and / or additional information.
