[0034] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0035] like Figure 1 As shown, at least one embodiment provides a water purifier for pharmaceutical production using a membrane process, comprising: a water pretreatment system A and a water treatment system B. The function of the water pretreatment system A is to treat raw water into drinking water, and the function of the water treatment system B is to treat the drinking water into water for injection. The raw water is domestic tap water.
[0036] like Figure 2 As shown, in some embodiments, the water pretreatment system A includes a filtration module 1 and a sterilization module 2.
[0037] like Figure 3 As shown, in some embodiments, the filtration module 1 includes: a first buffer tank 11, a first dosing unit 12, and a filtration unit 13.
[0038] In some embodiments, the first buffer tank 11 is used to receive raw water and deliver the received raw water to the filter unit 13.
[0039] In some embodiments, the first dosing unit 12 is used to add chemicals to the raw water delivered to the first buffer tank 11.
[0040] Optionally, the first dosing unit 12 may employ multiple injection valves to inject the corresponding drugs.
[0041] In this embodiment, the chemicals added by the first dosing unit 12 include: NaClO, NaOH, and HCl; wherein, NaClO and NaOH are used for sterilization, and HCl is used for descaling.
[0042] In some embodiments, a nanofiltration membrane 131 is provided in the filtration unit 13. The filtration unit 13 is used to receive the raw water after the dosing of chemicals and send it back to the first buffer water tank 11 after filtration by the nanofiltration membrane 131 to form a cycle. After the corresponding cycle time (i.e., the filtration is completed and the raw water becomes filtered raw water), the filtration unit 13 then sends the filtered raw water to the sterilization module 2.
[0043] In this embodiment, hollow fiber nanofiltration replaces traditional sand filtration, carbon filtration, and softening, effectively reducing the endotoxin level in the raw water; at the same time, by forming a circulation in the pipeline between the filtration unit 13 and the first buffer tank 11, the raw water can be kept flowing, preventing the growth of bacteria.
[0044] like Figure 4 As shown, in some embodiments, the sterilization module 2 is used to receive the filtered raw water sent by the filtration unit 13 and treat the filtered raw water into drinking water; wherein, the sterilization module 2 includes: a sterilization filter 21, a second buffer water tank 22, a pasteurization unit 23, a sterilization breather 24, and a second dosing unit 25.
[0045] In some embodiments, the sterilization filter 21 is used to receive the filtered raw water sent by the filtration unit 13 and sterilize the filtered raw water.
[0046] In this embodiment, the sterilization filter 21 serves as a safety guarantee to prevent rapid deterioration of water quality caused by damage to the preceding nanofiltration membrane 131.
[0047] like Figure 2 As shown, in some embodiments, a first loop pipe 211 is connected between the sterilization filter 21 and the first buffer tank 11.
[0048] In this embodiment, when the flow rate of the filtered raw water delivered by the filter unit 13 exceeds the processing efficiency of the sterilization filter 21, the first loop pipe 211 will be opened to send the excess filtered raw water back to the first buffer tank 11, thereby ensuring the flow of water and preventing the growth of bacteria.
[0049] like Figure 4 As shown, in some embodiments, the second dosing unit 25 is used to add chemicals to the filtered raw water entering the sterilization filter 21.
[0050] Optionally, the second dosing unit 25 may be equipped with an injection valve to inject the corresponding drug.
[0051] In this embodiment, the chemicals added by the second dosing unit 25 include NaOH and NaHSO3; wherein, NaOH is used to remove bacteria and CO2, and NaHSO3 is used to remove chlorine to prevent the reverse osmosis membrane from being oxidized in subsequent processes.
[0052] In some embodiments, the second buffer tank 22 is used to receive the filtered raw water delivered by the sterilization filter 21; wherein, the second buffer tank 22 is provided with a pasteurization unit 23 and a sterilization breather 24.
[0053] In some embodiments, the sterilization respirator 24 is installed on top of the second buffer tank 22 to prevent the second buffer tank 22 from inhaling microorganisms and impurities from the air.
[0054] In some embodiments, the pasteurization unit 23 is used to treat the water in the second buffer tank 22 to make the water drinkable; wherein, the pasteurization unit 23 may use industrial steam for heating and sterilization, and then use chilled water for cooling before delivery.
[0055] like Figure 1 As shown, at least one embodiment also provides a water treatment device for pharmaceutical manufacturing using a membrane process, comprising: a water treatment machine for pharmaceutical manufacturing using a membrane process and a water treatment system B.
[0056] like Figure 5As shown, in some embodiments, the water treatment system B includes: a UV sterilization module 3, a reverse osmosis module 4, and an electro-deionization device 5.
[0057] In some embodiments, the UV sterilization module 3 is used to receive and sterilize the drinking water delivered from the second buffer water tank 22; optionally, the UV sterilization module 3 includes: a UV cavity containing a UV lamp tube; wherein, UV is ultraviolet light.
[0058] In some embodiments, the reverse osmosis module 4 includes: a first reverse osmosis membrane unit 41 and a second reverse osmosis membrane unit 42; wherein, the second reverse osmosis membrane unit 42 is not shown in the figure, and it is the same as the first reverse osmosis membrane unit 41; optionally, both the first reverse osmosis membrane unit 41 and the second reverse osmosis membrane unit 42 include: a reverse osmosis membrane tube.
[0059] In this embodiment, a two-stage reverse osmosis process can effectively remove ions from drinking water, thereby purifying the water quality.
[0060] In some embodiments, the electro-deionization device 5 can further remove ions from the water.
[0061] In some embodiments, the water treatment system B further includes an ultrafiltration membrane unit 6, which is used to receive and treat the water after it has been treated by the electro-deionization device 5; optionally, the ultrafiltration membrane unit 6 includes an ultrafiltration membrane tube, which uses a hollow fiber membrane with a molecular weight cutoff of 6000 Daltons, and can effectively intercept endotoxins under low pressure operation.
[0062] In some embodiments, a second loop pipe 51 is connected between the electro-deionization device 5 and the second buffer tank 22. The second loop pipe 51 is adapted to return water that the ultrafiltration membrane unit 6 cannot process to the second buffer tank 22, so that the water always remains flowing.
[0063] In summary, this all-membrane pharmaceutical water purifier treats raw water into drinking water through water pretreatment system A, and then treats the drinking water into water for injection through water treatment system B. Furthermore, the first loop pipe 211 keeps the water flowing during the treatment process, preventing bacterial growth.
[0064] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.
[0065] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.
[0066] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.
[0067] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.
[0068] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.
[0069] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0070] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0071] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0072] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0073] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
