Description

Technical Field

[0001] The invention belongs to the technical field of reverse osmosis concentrated water treatment accessory devices, and in particular relates to a reverse osmosis concentrated water treatment device. Background Art

[0002] Reverse osmosis brine is a special kind of brine. The reverse osmosis membrane converts 80% to 85% of the incoming water into clean water. At the same time, all the retained substances are concentrated in brine that accounts for 15% to 20% of the incoming water volume. The pollutant concentration in the brine is about 2 to 3 times that of the incoming water. Ultrafiltration is one of the membrane separation technologies driven by pressure. Its purpose is to separate large molecules from small molecules. The membrane pore size is between 20-1000A°. The hollow fiber ultrafiltration membrane has the advantages of high filling density per unit container and small footprint. The reverse osmosis brine treatment device is an auxiliary device used for ultrafiltration treatment of reverse osmosis brine in the brine discharge process to recover water in the brine and reduce water waste. It has been widely used in the field of reverse osmosis brine treatment.

[0003] When an existing reverse osmosis concentrated water treatment device is in use, for example, the publication number is CN111773930A.

[0016] The beneficial effects of the present invention are: 1. This reverse osmosis concentrated water treatment device facilitates the addition of drugs through the drug inlet at the top of the drug storage tank. The filter frame at the upper end of the internal clamping can perform preliminary filtration on the added drugs. This can remove large particles of impurities or undissolved agglomerates in the drugs, ensuring the purity and quality of the drugs entering the storage tank, preventing impurities from clogging or damaging equipment in subsequent processes, and also ensuring the stability and effectiveness of the drugs during the treatment process. For example, when adding drugs such as flocculants, the filter frame can filter out impurities generated by storage or transportation, allowing pure drugs to enter the next stage. 2. This reverse osmosis concentrated water treatment device features a stirring assembly located in the middle of the upper end of the support base. Its stirring tube is connected via a second flange, and a motor drives a rotating rod to rotate the scraper. This design allows for thorough mixing of drugs in the stirring tube, preventing drug precipitation or stratification. This is particularly true for drug solutions that require uniform dispersion, such as acid-base regulators. The stirring action ensures that the drugs are evenly distributed in the concentrated water before entering the reverse osmosis system, improving treatment efficiency. Furthermore, the stirring tube is arranged in an oblique structure, with the left side lower and the right side higher, which facilitates better mixing of drugs during flow. This structure increases the turbulence of the liquid within the tube, ensuring more complete contact between the drugs and the concentrated water. 3. The reverse osmosis concentrated water treatment device is fixed to the inner wall of the third connecting pipe through the fixed sleeve in the drug release assembly. The lower end of the movable rod is connected to the float, and the float is engaged with the fixed block. When the drug liquid level in the second connecting pipe changes, the float will float up and down accordingly, and the amount of drug released is controlled by the movable rod. For example, when the liquid level rises, the float rises, which can make the opening on the fixed block open, allowing the drug to flow out through the opening; when the liquid level drops, the float drops, and the drug release channel is closed to prevent the drug from leaking. This automatic adjustment function can accurately control the amount of drug released, avoid drug waste, and at the same time ensure the stability of drug concentration during the reverse osmosis concentrated water treatment process, thereby improving treatment efficiency.

[0017] 4. The reverse osmosis concentrated water treatment device is connected by flanges, bolts, etc. through various components of the entire device, such as the first flange, the second flange, etc. This connection method makes the device more convenient and quick during installation and disassembly. For example, when the stirring tube needs to be repaired or replaced, it is only necessary to loosen the bolts at the second flange to separate the various sections of the stirring tube, which is convenient for operation. At the same time, the positions of the various components are reasonably arranged. For example, the support base integrates the drug storage tank, the first water pump and other components together, making the device compact in structure and occupying a small area. In addition, when a fault occurs, the relevant components can be quickly located and repaired. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1: See also Figures 1-10 As shown, this embodiment provides a reverse osmosis concentrated water treatment device.

[0035] The invention comprises: a support base 1, a medicine storage tank 2 is fixedly installed on the upper end of the support base 1, and a filter frame 3 is engaged with the inner upper end of the medicine storage tank 2, a medicine inlet 4 is fixedly connected to the upper end of the medicine storage tank 2, a first water pump 5 is fixedly installed on the left side of the lower end of the support base 1, and the water inlet end of the first water pump 5 is connected to the water inlet pipe 6, the water outlet end of the first water pump 5 is fixedly connected to the first connecting pipe 7, the right lower end of the medicine storage tank 2 is fixedly connected to the second connecting pipe 9, and the lower end of the second connecting pipe 9 is connected to the third connecting pipe 10 through the first flange 8, a stirring component, the stirring component is fixedly installed in the middle position of the upper end of the support base 1, a medicine releasing component, the medicine releasing component is fixedly installed inside the third connecting pipe 10, a first water pipe 20, the first water pipe 20 is fixedly connected to the right side of the lower end of the stirring rod 11, and the other end of the first water pipe 20 is fixedly connected On the filter tank 21, a filter plate 22 is engaged inside the filter tank 21, and a fixing frame 23 is wrapped around the outside of the filter tank 21. The right side of the filter tank 21 is connected to the water inlet end of the second water pump 25 through the second water pipe 24, and the water outlet end of the second water pump 25 is connected to the treatment box 26 through the second water pipe 24. A heating plate 27 is fixedly installed at the lower end of the interior of the treatment box 26. The upper right end of the treatment box 26 is connected to the storage tank 29 through the delivery pipe 28, and the middle position of the lower end of the back side of the storage tank 29 is fixedly connected with a water outlet 30. The first water pump 5 (water inlet pump) of the present invention is used to draw concentrated water from the water inlet pipe 6 into the system to provide initial power. The recommended model is a centrifugal pump (such as IS type, IH type chemical pump): suitable for conveying liquids containing particles or corrosive liquids, with large flow rate and moderate head. The flow rate is selected according to the processing volume (such as 5-20 m 3 / h), the head is determined according to the water inlet height and pipeline resistance (such as 10-30 meters), the centrifugal pump impeller design can effectively avoid impurity clogging, suitable for treating suspended matter or particulate matter contained in reverse osmosis concentrated water, if the concentrated water is corrosive (such as high salt, high acid and alkali), stainless steel (such as 316L) or fluoroplastic lined centrifugal pump (such as IH type) can be selected. The centrifugal pump has high efficiency in a large flow range and can reduce operating energy consumption. The second water pump 25 (post-filtration booster pump) pressurizes the filtered concentrated water and sends it into the treatment box 26 to ensure stable water supply for subsequent treatment processes (such as heating and reaction). High-pressure plunger pump (such as reciprocating pump or metering pump): provides high head and stable pressure, suitable for occasions where precise flow control is required. The head is selected according to the pressure requirement of the treatment box (such as 30-100 meters), and the flow rate matches the first water pump (such as 5-20 m 3 The plunger pump provides stable, high-pressure output, ensuring uniform distribution of the concentrated water within the treatment tank 26 and preventing inadequate treatment due to insufficient pressure. Variable frequency speed regulation or mechanical adjustment allows flexible flow control to meet diverse treatment requirements. The plunger pump's piston and cylinder are made of wear-resistant materials (such as ceramic or carbide) to resist abrasion by particulate matter in the concentrated water. The stirring motor 13 (driving the stirring assembly) rotates the stirring rod 11 and scraper 15 to mix the drug with the concentrated water and clean the stirring tube 11. The three-phase asynchronous motor (such as the Y2 series or YX3 high-efficiency energy-saving motor) has a power rating selected based on the stirring load (e.g., 1.5-3 kW) and an adjustable speed (e.g., 1000-1500 RPM). It is IP55 or IP65 rated, making it suitable for humid environments. The YX3 motor boasts an efficiency exceeding 90%, reducing power consumption. If resistance is encountered during stirring (e.g., due to sticky drug or entangled impurities), the motor can temporarily overload to avoid downtime. The speed can be adjusted using a frequency converter or gear reducer to meet diverse stirring requirements.

[0036] Example 2: This embodiment provides a reverse osmosis concentrated water treatment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0037] The upper end of the filter frame 3 is movably engaged with the medicine storage tank 2, and the outer side of the filter frame 3 is fixedly installed on the medicine storage tank 2 by bolts, and the lower end of the bolt is sleeved with a nut, and the upper and lower ends of the bolt are sleeved with gaskets, and one group of gaskets is in contact with the bolt and the medicine storage tank 2, and the other group of gaskets is in contact with the nut and the filter frame 3. The second connecting pipe 9 and the third connecting pipe 10 are connected through the first flange 8. The first flange 8 is inserted with a bolt, and the lower end of the bolt is sleeved with a nut. The upper right end of the first connecting pipe 7 is fixedly installed on the stirring assembly through the first flange 8 and the bolt. The upper end of the filter frame 3 is movably engaged with the medicine storage tank 2, and the outer side is fixed by bolts. This combined fixing method makes the position of the filter frame 3 in the medicine storage tank 2 very stable. The drug storage tank 2 may be subject to external forces such as liquid flushing and stirring. The stable filter frame 3 can prevent it from displacement or shaking, ensuring the normal operation of the filtering function. For example, when adding drugs or stirring drugs, the filter frame 3 will not be displaced from its original position due to the flow of liquid, thereby ensuring the consistency of the filtering effect. The gaskets sleeved at the upper and lower ends of the bolt play a key sealing role. One set of gaskets is in contact between the bolt and the drug storage tank 2, and the other set of gaskets is in contact between the nut and the filter frame 3. This design can effectively prevent drugs from leaking from the connection between the filter frame 3 and the drug storage tank 2. During the drug storage process, drugs usually have certain corrosiveness or viscosity. A good seal can prevent drugs from leaking to the outside of the storage tank, which not only reduces The filter frame 3 is movably engaged with the medicine storage tank 2, and this design makes the filter frame 3 more convenient and quick to install. When installing or replacing the filter frame 3 for the first time, it is only necessary to put the filter frame 3 into the designated position of the medicine storage tank 2 according to the engaging manner, and then fix it with bolts. Compared with the traditional installation that requires precise alignment and complicated fastening methods, this movable engaging design greatly saves installation time and labor costs. When the filter frame 3 needs to be cleaned, the filter element replaced or inspected, the filter frame 3 can be easily removed from the medicine storage tank 2 by loosening the bolts, which makes maintenance work simple. It is easy to operate and can promptly detect and deal with problems such as blockage and damage of the filter frame 3 to ensure the normal operation of the drug filtration system. For example, if the filter element of the filter frame 3 is blocked by impurities, the staff can quickly remove it for cleaning or replacement without causing a long interruption to the entire drug storage and processing system. The second connecting pipe 9 is connected to the third connecting pipe 10 through the first flange 8. Bolts are inserted into the first flange 8. This flange connection method can withstand greater pressure and tension. In the reverse osmosis concentrated water treatment system, the liquid in the pipeline may have a certain pressure. Especially when the water pump is running or the pressure changes during the treatment process, the flange connection can ensure that the connection between the pipelines is tight and will not loosen or fall off due to pressure. For example,When the first water pump 5 is running, water flows through the connecting pipe and generates a certain pressure. The flange connection can ensure the stability of the pipeline system and prevent problems such as water leakage or pipe rupture. The bolts on the flange are usually evenly distributed, which can make the force at the connection more balanced. When the pipeline is subjected to internal pressure or external vibration, the uniform force can avoid local stress concentration, reduce fatigue damage at the connection part, and extend the service life of the pipeline and flange.

[0038] Example 3: This embodiment provides a reverse osmosis concentrated water treatment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0039] The stirring assembly includes a stirring tube 11, which is fixedly connected to the lower end of the third connecting tube 10, and the lower end of the stirring tube 11 is fixedly installed in the middle position of the support base 1. A second flange 12 is provided at both ends of the left and right stirring tube 11. A motor 13 is fixedly installed on the right side of the stirring tube 11, and the motor 13 is fixedly connected to a rotating rod 14 through a rotating shaft. A scraper 15 is fixedly connected to the outer side of the rotating rod 14. The stirring tube 11 is composed of three groups of tube bodies connected with bolts through the second flange 12. The stirring tube 11 is arranged in an oblique structure. The stirring tube 11 is a left-low and right-high structure. The outer side of the scraper 15 abuts against the inner wall of the stirring tube 11. The oblique structure of the stirring tube 11 (left-low and right-high) can make full use of gravity and fluid flow characteristics to promote the mixing and flow of drugs and concentrated water in the pipeline. The left-low and right-high structure makes the gravity and stirring action cooperate when the liquid flows from the left side (low position) to the right side (high position) to enhance the mixing effect and avoid drug precipitation. The oblique structure can reduce cavitation when the liquid flows at high speed, extend the pipeline and equipment The service life of the stirring tube 11 is extended. The stirring tube 11 is composed of three groups of tube bodies connected by the second flange 12 and bolts. This modular design makes the disassembly and assembly of the stirring tube more convenient. If a section of the tube body is damaged or needs to be cleaned, it is only necessary to remove the corresponding flange bolts to replace or repair it. There is no need to dismantle the stirring tube 11 as a whole, which reduces maintenance costs and time. The length or angle of the stirring tube 11 can be adjusted according to actual needs to adapt to different processing scales or process requirements. The connection method of the second flange 12 and the bolts ensures the sealing of the stirring tube 11, prevents the leakage of drugs or concentrated water, and avoids pollution or corrosion to the environment and equipment. The bolts are evenly distributed, ensuring that the stirring tube 11 is balanced in force during operation, avoiding loosening or deformation due to vibration or pressure. The motor 13 drives the rotating rod 14 to rotate through the rotating shaft, driving the scraper 15 to move on the inner wall of the stirring tube 11 to achieve sufficient stirring of the drugs. The rotation of the scraper 15 can evenly mix the drugs and concentrated water, avoid drug precipitation or stratification, and improve processing efficiency. The power of the motor 13 can be selected according to the viscosity of the drugs (such as 1.5-3kW), ensuring that high-viscosity drugs (such as flocculants) can be fully stirred. The outer side of the scraper 15 is close to the inner wall of the stirring tube 11, which can remove drug residues or dirt on the tube wall during stirring to prevent corrosion and clogging. The design of the scraper 15 reduces the accumulation of adherents on the tube wall, extends the cleaning cycle of the stirring tube 11, reduces maintenance workload, prevents long-term corrosion of the tube wall by drug residues, and extends the service life of the stirring tube 11. The oblique structure of the stirring tube 11 cooperates with the rotation direction of the scraper 15 to form a vortex effect, further improving the mixing uniformity of the drug and concentrated water. As the scraper 15 moves within the inclined pipe, gravity assists in removing pipe wall residue, enhancing its self-cleaning capabilities. The efficient mixing action of the stirring assembly accelerates the reaction between drugs (such as pH regulators and flocculants) and concentrated water, improving treatment efficiency. The design of the scraper 15 effectively prevents drug agglomeration, ensuring that the drugs are fully dissolved and effective. The motor 13 can be controlled by variable frequency speed regulation to meet the treatment requirements of different drug dosages or concentrated water properties. The stirring tube 11 and scraper 15 can be made of stainless steel (such as 316L) or fluoroplastic-lined materials to resist concentrated water corrosion and extend equipment life.

When the liquid level in the third connecting tube 10 (such as concentrated water or treated liquid medicine) rises, the float 18 will float with the liquid level and push the movable rod 17 to move upward. This design uses the principle of buoyancy to realize automatic sensing of liquid level changes, thereby controlling the opening and closing of the drug release component. The float 18 cooperates with the slot of the fixed block 19 to ensure that the float 18 can move up and down stably when the liquid level changes, avoiding misoperation or jamming, and ensuring the accuracy of drug release control. The movable rod 17 is inserted into the slot of the fixed sleeve 16. When the float 18 moves up and down, the movable rod 17 slides in the fixed sleeve 16 accordingly. This mechanical linkage design does not require an external power supply or complex sensor, and relies on the buoyancy and gravity of the liquid to realize the drug release component. Automatic opening and closing, simple structure and high reliability, the slot design of the movable rod 17 can ensure the stability of its movement trajectory, avoid misoperation due to vibration or external force, thereby ensuring the sealing of the drug release component in the closed state and preventing drug leakage, the integration of the fixed sleeve 16 and the third connecting pipe 10: the drug release component is directly fixed to the inner wall of the third connecting pipe 10 through the fixed sleeve 16, without the need for additional installation space, the structure is compact, and it is easy to integrate into the existing system, a through hole is opened in the middle position of the fixed block 19, allowing the liquid (such as concentrated water) to flow normally, while providing guidance and limiting effects for the float 18, ensuring that the float 18 is always in the correct position when the liquid level changes, the surface of the float 18 and the movable rod 17 are usually made of smooth materials (such as stainless steel or plastic), reducing Less impurities in the liquid adhere to prevent clogging, the fixed sleeve 16, the fixed block 19 and other components can be made of stainless steel (such as 316L) or corrosion-resistant plastic (such as PVC, PP), which can adapt to the corrosive environment of reverse osmosis concentrated water or chemical drugs and extend the life of the equipment. When the liquid level in the third connecting pipe 10 reaches a certain height, the float 18 rises and pushes the movable rod 17 to trigger the drug release component to open. This design can release drugs according to actual liquid level requirements, avoid excessive drug administration, save costs and reduce environmental pollution. When the liquid level drops, the float 18 drops accordingly, and the movable rod 17 resets and closes the drug release component to prevent continuous release of drugs and ensure accurate control of the drug release amount. By adjusting the size or weight of the float 18, the sensitivity of the liquid level trigger can be changed.Adaptable to different drug delivery requirements (such as small amount of dripping or large amount of release), this design is not only suitable for chemical drugs, but also for the delivery of liquids with different properties such as flocculants and acid-base regulators, and has a wide range of applicability.

[0042] Example 5: This embodiment provides a reverse osmosis concentrated water treatment device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] There are three groups of filter plates 22, which are movably engaged with the filter tank 21, and the filter tank 21 is provided with a slot that matches the filter plate 22. The front end of the filter plate 22 is fixedly connected with a handle, and the fixing frame 23 is composed of two groups of arc-shaped frames that are hingedly connected. The other ends of the two groups of frames are fixed by bolts and nuts. The inner wall of the fixing frame 23 is in contact with the outer side of the filter tank 21. The position of the fixing frame 23 corresponds to the filter plate 22. Three groups of filter plates 22 are provided, and each group of filter plates 22 is movably engaged with the filter tank 21. This modular design The design allows each filter plate 22 to be independently disassembled and replaced, which is convenient for maintenance and cleaning. Single, double or triple filter plates 22 can be selected according to actual needs to adapt to different filtering precision or flow requirements. When a filter plate 22 is blocked or damaged, it can be replaced separately without stopping the machine, reducing system downtime. A card slot that matches the filter plate 22 is provided on the filter tank 21 to ensure that the filter plate 22 is firmly installed to avoid displacement caused by liquid impact or vibration. The front end of the filter plate 22 is fixed with a handle for easy manual installation or removal of the filter plate 22, especially in high temperature or high humidity. Under high-temperature conditions, the operation is safer and more convenient. The three groups of filter plates 22 can perform multi-stage filtration on the liquid to improve the filtration effect and disperse the fluid pressure to avoid overloading of a single filter plate 22. The slot design makes the liquid evenly distributed between the filter plates 22, reducing the risk of local blockage and extending the service life of the filter plates 22. The fixed frame 23 is composed of two groups of arc-shaped frame hinges. The inner wall contacts the outside of the filter tank 21 and can fit the contour of the filter tank 21 closely to prevent liquid leakage. The arc structure can adapt to the cylindrical or other curved shapes of the filter tank 21. It has strong versatility and high stability after installation. The two sets of frames are connected by a hinge and can be quickly expanded or closed, which is convenient for installation and disassembly; the other end is fixed by bolts and nuts to ensure the stability of the overall structure. The bolt fixing method allows the tightness of the fixing frame 23 to be adjusted to avoid deformation of the filter tank 21 or damage to the seal due to over-tightening. The position of the fixing frame 23 corresponds to the filter plate 22, which can provide additional support for the filter plate 22 to prevent it from being deformed due to liquid pressure or vibration. The fixing frame 23 contacts the outside of the filter tank 21 to prevent the filter plate 22 from directly rubbing against the tank body, thereby extending the service life of the tank body and the filter plate 22.

[0044] Example 6: The front surface of the treatment box 26 is hingedly connected with a closed door, and the upper end of the delivery pipe 28 is set in an oblique structure. The left and right sides of the upper end of the interior of the storage tank 29 are fixedly connected with guide plates, and the two sets of guide plates are distributed oppositely with oblique structures. The lower end of the interior of the storage tank 29 is set in an oblique structure, and one inclined end is set at the position of the water outlet 30. The hinged closed door is easy to open: the closed door is hingedly connected to the front surface of the treatment box 26 and can be easily opened and closed, which is convenient for personnel to inspect, clean or replace parts inside the treatment box 26. When the closed door is closed, it can effectively seal the treatment box 26 to prevent internal liquid or gas from leaking, and at the same time avoid external impurities from entering the box, ensuring the safety and cleanliness of the treatment process. The closed door can be made of the same corrosion-resistant material as the treatment box 26 (such as stainless steel or plastic-lined material) to resist erosion by chemical media or high temperature environment, thereby extending the life of the equipment. The upper end of the delivery pipe 28 is set in an oblique structure, which can be used with the help of weight The force promotes the flow of liquid (such as concentrated water or liquid medicine), reduces pumping energy consumption, and reduces operating costs. The oblique structure helps to avoid the formation of vortexes or cavitation in the pipeline, while reducing the risk of impurity precipitation and blockage. The oblique delivery pipe 28 can adapt to the height difference between different equipment, optimize the spatial layout, and avoid pressure drop problems caused by excessive bending or excessive length of the pipeline. The guide plates on the left and right sides of the upper end of the storage tank 29 are distributed oppositely in an oblique structure, which can evenly disperse the inflowing liquid into the tank body, avoiding the liquid directly impacting the tank wall or local accumulation. The oblique design of the guide plate can guide the liquid to flow slowly along the tank wall, reduce turbulence and bubble generation, and reduce erosion and corrosion of the tank body. The lower end of the interior of the storage tank 29 is set in an oblique structure, and the inclination direction is towards the water outlet 30, which can make the liquid flow naturally to a low place, realizing efficient collection and discharge. The oblique design avoids the accumulation of liquid at the bottom of the tank, reduces the risk of impurity deposition and corrosion, and is easy to clean and maintain.

[0045] During use: the drug storage tank 2 is used to store the chemical agents (such as acid-base regulators, flocculants, etc.) required for treating reverse osmosis concentrated water. Drugs are added to the drug storage tank 2 through the drug inlet 4 to ensure continuous supply. The drug release assembly is fixed inside the second connecting pipe 9. The float 18 senses the liquid level change and automatically controls the drug release. When the liquid level in the third connecting pipe 10 rises, the float 18 pushes the movable rod 17, triggering the drug release mechanism. The drug is then added from the storage tank to the stirring assembly through the second connecting pipe 9 and the third connecting pipe 10. The stirring assembly includes a stirring tube 11, a motor 13, a rotating rod 14 and a scraper 15. The motor 13 drives the rotating rod 14 to rotate, driving the scraper 15 to move on the inner wall of the stirring tube 11 to fully mix the medicine and concentrated water to avoid precipitation or agglomeration. The stirring tube 11 has an inclined structure with the left side low and the right side high, using gravity to assist the liquid flow and enhance the mixing effect. The filter frame 3 in the drug storage tank 2 is used to filter large particles of impurities in the medicine to prevent blockage of subsequent pipelines. The filter plate 22 in the filter tank 21 further filters suspended matter or flocculated sediment in the mixed liquid to ensure that the liquid entering the treatment box 26 is clean.

[0046] The first water pump 5 pumps the concentrated water in the water inlet pipe 6 to the first connecting pipe 7, injects it into the drug storage tank 2 or the stirring assembly, and mixes it with the drug. The second water pump 25 pumps the filtered liquid from the filter tank 21 to the treatment box 26 for subsequent treatment. A heating plate 27 is installed at the lower end of the treatment box 26 to heat the mixed liquid (such as evaporation concentration, sterilization or acceleration of chemical reaction) to meet specific process requirements (such as concentration reduction and water quality stabilization). The treated liquid flows into the storage tank 29 through the inclined conveying pipe 28, using gravity to assist the flow and reduce energy consumption. The upper end guide plates are distributed in opposite directions to evenly disperse the incoming liquid and reduce impact and turbulence. The lower end inclined surface design allows the liquid to flow naturally to the water outlet 30, which is convenient for centralized discharge or further treatment. The treated liquid is discharged through the water outlet 30 and can be connected to subsequent processes (such as reuse, discharge or further purification).
