Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to energy-saving and environment-friendly automatic sewage treatment equipment. Background Art

[0002] MBR (Membrane Bioreactor) is an advanced sewage treatment technology that combines bioreactor and membrane filtration technology. The MBR membrane sewage treatment system decomposes and degrades organic matter in sewage by introducing microorganisms into the bioreactor, and uses membrane filters to separate solids and liquids. The membrane filters of the MBR system usually use microporous membranes, which can effectively prevent the passage of suspended matter, bacteria, viruses and other microorganisms, thereby achieving efficient solid-liquid separation, high effluent cleanliness, and small footprint. It has been widely and maturely used in the sewage treatment industry.

[0003] During the use of the existing MBR membrane sewage treatment device, sludge will continue to be deposited on the membrane surface. The sludge deposited on the membrane surface needs to be removed from the membrane assembly from the treatment tank after a period of use, and then the membrane surface is rinsed with a large amount of water to remove the sludge. This consumes a large amount of water resources, which is not in line with the concept of energy conservation and environmental protection. It also requires a large amount of manpower for cleaning, which is inefficient.

[0004] Therefore, there is a need for an energy-saving and environmentally friendly sewage treatment device to reduce the consumption of water resources during sewage treatment. Summary of the invention

[0005] The purpose of the present invention is to provide an energy-saving and environmentally friendly automated sewage treatment equipment to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an automated sewage treatment device comprises a device body, a lifting pump, a membrane assembly, an aeration assembly, a fan, a water production pump, and a control assembly. A pretreatment tank, a reaction tank, an equipment warehouse, and a clean water tank are sequentially arranged in the device body. The lifting pump is located in the pretreatment tank, and a water outlet of the lifting pump is connected to the reaction tank. The membrane assembly and the aeration assembly are located in the reaction tank, and the membrane assembly is connected to a water inlet of the water production pump. The aeration assembly is connected to an air outlet of the fan. The fan and the water production pump are located in the equipment warehouse, and a water outlet of the water production pump is connected to the clean water tank. The control assembly is electrically connected to the membrane assembly and the lifting pump.

[0007] The device body is the installation basis of each component. The sewage is first stored in the pretreatment tank to prevent the flow of sewage from being unstable and affecting the treatment effect. The sewage is then input into the reaction tank through the lifting pump placed at the bottom of the pretreatment tank. The reaction tank is used to treat the sewage and degrade and decompose the organic matter in the sewage through the action of microorganisms. After the sewage undergoes biological reaction, it is sent to the membrane module by applying appropriate pressure through the water production pump. The suspended matter, organic matter and microorganisms in the sewage are effectively intercepted by the membrane module. Clean water is pumped into the clean water tank through the water production pump for collection. The fan provides gas for the aeration component. The fan is started to introduce high-pressure gas into the aeration component. The aeration component evenly distributes the gas to the membrane module, providing sufficient oxygen for the microorganisms in the reaction tank and accelerating the reaction. The rising of bubbles can drive the water flow, and the flow of water can play a certain cleaning role on the membrane module, preventing sludge from being deposited on the membrane module and affecting the flux of the membrane module. The equipment warehouse provides a stable working environment for the fan, water production pump and control component. The control component automatically controls the action of each component to realize the automatic operation of the device.

[0008] Furthermore, a water inlet pipe is provided on one side of the pretreatment tank, a grille is provided inside the water inlet pipe, and a drain valve is provided on one side of the clean water tank.

[0009] Sewage enters the pretreatment tank through the water inlet pipe. By setting a grid in the water inlet pipe, large-volume debris in the sewage can be screened out to prevent clogging by debris. The treated sewage is placed in the clean water tank. When needed, the drain valve can be opened to discharge the treated sewage for reuse.

[0010] Furthermore, the aeration assembly includes an aeration frame and an aeration pipe. The aeration frame is placed in the reaction tank. The aeration pipe is tightly connected to the aeration frame. The aeration pipe is connected to the air outlet of the fan. The air outlet of the aeration pipe faces the membrane assembly. The membrane assembly is placed above the aeration frame.

[0011] The aeration frame provides an installation basis for the aeration tube. The aeration tube is provided with a number of air outlets. When the fan is started, the gas is transported into the aeration tube and discharged through the air outlets. The number of air outlets can increase the aeration rate, accelerate the dissolution of oxygen, provide sufficient oxygen for the microorganisms in the reaction tank, and accelerate the decomposition of sewage. The aeration component is set directly below the membrane component. Aeration will produce air agitation, and the sewage will flow upward with the airflow, generating shear force on the surface of the membrane component to prevent sludge from depositing on the surface, thereby reducing pollution.

[0012] Furthermore, the membrane assembly includes a hollow diaphragm, a membrane frame, a plastic bracket, and an electrode plate. The hollow diaphragm is tightly connected to the membrane frame, the hollow diaphragm is connected to the water inlet of the water production pump, and the electrode plate is fixed to both sides of the membrane frame through the plastic bracket.

[0013] The membrane frame provides an installation basis for the hollow diaphragm. Several groups of hollow diaphragms are arranged on the membrane frame. The hollow diaphragm uses a microporous membrane, which can effectively prevent the passage of suspended matter, bacteria, viruses and other microorganisms, thereby achieving efficient solid-liquid separation. After being treated in the pretreatment tank, the sewage reaches the reaction tank and flows evenly from the surroundings to the surface of the hollow diaphragm. Through the negative pressure suction of the water production pump, the activated sludge and other substances in the sewage are separated by the hollow diaphragm, and the water flows from the surface of the hollow diaphragm to the inside and is pumped into the clean water tank through the water production pump. The plastic bracket is fixed on the membrane frame to provide support for the electrode plate.

[0014] Furthermore, the electrode plate is made of carbon felt, and is provided with honeycomb holes. A conductive rod is provided in the membrane frame, and the conductive rod is electrically connected to the electrode plate. The electrode plate is inoculated with electrogenic bacteria, and the conductive rod is made of stainless steel.

[0015] By setting honeycomb holes on the electrode plate, not only can the fluidity of sewage be guaranteed, but also the area of ​​the electrode plate can be increased to provide a suitable living environment for the electrogenic bacteria. The treated sewage contains a large amount of organic matter, which provides nutrition for the electrogenic bacteria. The electrode plate serves as the anode and the conductive rod serves as the cathode. The electrogenic bacteria at the anode will decompose the organic matter in the sewage into electrons and protons. Then the generated electrons reach the cathode through the wire, and the protons reach the cathode through diffusion. Finally, under the action of the aeration component, the sewage at the conductive rod contains a large amount of oxygen, and redox reactions occur on the cathode. The substance and charge are conserved throughout the process. Electrons flow continuously in the external circuit to form an electric current, thus forming a bioelectric field between the electrode plate and the conductive rod. Under the stimulation of the electric field, not only can the activity of microorganisms in the sewage be improved, thereby improving the purification efficiency, but also because most of the sludge particles are negatively charged, they migrate away from the membrane surface under the electrostatic repulsion in the electric field. At the same time, with the hydraulic shearing effect generated by aeration, the pollutants adsorbed on the membrane surface are more easily blown off, achieving the effect of cleaning the membrane.

[0016] Furthermore, the membrane assembly also includes an arc-shaped shield and an exhaust pipe. The arc-shaped shield is tightly connected to the membrane frame, the arc-shaped shield is located above the membrane frame, the exhaust pipe is connected to the arc-shaped shield, and the exhaust pipe extends out of the reaction tank.

[0017] Aeration components will generate a large amount of gas when they are working. By installing an arc-shaped shield on the membrane frame and submerging the shield in sewage, the gas generated by aeration can be collected. The bubbles generated by aeration gradually gather in the arc-shaped shield. When the gas in the arc-shaped shield gathers to a certain extent, the pressure in the arc-shaped shield increases and is discharged through the exhaust pipe. During the exhaust process, under the action of pressure, the gas will be quickly discharged through the exhaust pipe, and the sewage in the reaction tank will quickly fill into the arc-shaped shield. The flow of water will flush the membrane component to clean it, and the rapidly flowing sewage will impact the inner wall of the arc-shaped shield, generating a vibration, and transmitting the vibration to the membrane frame to avoid sludge deposition on the membrane component. As aeration proceeds, the cavity in the arc-shaped shield will continuously cycle between gas collection and gas release, thereby continuously cleaning the membrane component and increasing the service life of the membrane component.

[0018] Furthermore, the exhaust pipe includes a pipe body, a first spring, and a first slider. The first spring is fixedly connected to the pipe body, and the first slider is slidably connected to the pipe body.

[0019] The first slider closes the air outlet of the exhaust pipe under the action of its own gravity and the elastic force of the first spring. As aeration proceeds, the pressure in the arc-shaped protective cover gradually increases, thereby giving the first slider a thrust, thereby overcoming the elastic force of the first spring, opening the air outlet of the exhaust pipe, and exhausting the gas. The first slider automatically opens and closes the air outlet of the exhaust pipe according to the pressure in the arc-shaped protective cover, thereby realizing automatic control of the exhaust.

[0020] Furthermore, the control component includes a protective shell, an iron core, a coil, a second slider, a second spring, a rotating rod, and a wire. The protective shell is tightly connected to the equipment compartment, the iron core is tightly connected to the protective shell, the coil is wound on the iron core, the negative pole of the coil is connected to the electrode plate, the positive pole of the coil is connected to the conductive rod, a sliding cavity is provided in the protective shell, the second slider is slidingly connected to the sliding cavity, the rotating rod is hinged to the wire, the lower end of the second spring is tightly connected to the protective shell, the upper end of the second spring is tightly connected to the rotating rod, and the wire is electrically connected to the lifting pump.

[0021] By directing the current generated by the electrogenic bacteria on the electrode plate to the coil, a simple electromagnet is formed because the coil is wound around the iron core. The second slider is made of iron material, so when the coil is energized, under the attraction of the magnetic force, the second slider will overcome its own gravity and slide upward along the sliding cavity, away from the rotating rod. When the current decreases, it indicates that the nutrients required by the electrogenic bacteria are insufficient, and new sewage needs to be introduced from the pretreatment tank to replenish the organic matter in the reaction tank. As the current decreases, the magnetic force generated by the coil and the iron core will become smaller. The second slider will slide downward along the sliding cavity under the influence of its own gravity and abut against the rotating rod, thereby compressing the second spring so that the rotating rod is connected to the wire, thereby giving an electrical signal to the lift pump, automatically starting the lift pump to pump sewage into the reaction tank, and after the electrogenic bacteria are replenished with organic matter, the current generated will increase, and the second slider will move up under the action of the magnetic force, disconnect the wire, and automatically shut down the lift pump.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention forms a bioelectric field on the membrane assembly by inoculating electrogenic bacteria on the electrode plate in combination with the conductive rods, and the electric field increases the activity of the microorganisms and improves the purification efficiency. The organic matter in the sewage is used as the energy source for the electrogenic bacteria, and an electric current can be generated without an external power supply, thereby reducing energy consumption.

[0023] The bioelectric field formed on the membrane assembly can also produce electrostatic repulsion, pushing the negatively charged sludge particles in the sewage away from the membrane surface. At the same time, with the hydraulic shear effect generated by aeration, pollutants adsorbed on the membrane surface are more easily blown off, achieving the effect of cleaning the membrane.

[0024] By submerging the arc-shaped shield in sewage, the gas generated by aeration can be collected. As aeration proceeds, the pressure in the arc-shaped shield will gradually increase, thereby giving a thrust to the first slider, thereby overcoming the elastic force of the first spring, opening the air outlet of the exhaust pipe, and exhausting the gas. The first slider will automatically open and close the air outlet of the exhaust pipe according to the pressure in the arc-shaped shield, thereby realizing automatic exhaust control. The gas will be quickly discharged through the exhaust pipe, and the sewage will quickly fill into the arc-shaped shield, and the flow of water will flush the membrane component to play a cleaning role. The rapidly flowing sewage will impact the inner wall of the arc-shaped shield to generate a vibration, and transmit the vibration to the membrane frame to avoid sludge deposition on the membrane component. As aeration proceeds, the cavity in the arc-shaped shield will continuously circulate between gas collection and gas release, thereby continuously and automatically cleaning the membrane component, collecting and utilizing the gas generated during aeration, and automatically cleaning the membrane component, thereby reducing the cleaning frequency of the membrane component, saving water resources, and being beneficial to energy conservation and environmental protection.

[0025] By utilizing the strength of the current generated by the electrogenic bacteria, a simple electromagnet is formed through the combination of a coil and an iron core, which cooperates with the second slider to automatically control the opening and closing of the lift pump, so that the organic matter content in the reaction tank is maintained within a stable range, thereby ensuring the activity of the electrogenic bacteria.

[0038] The present invention provides a technical solution:

[0039] like Figure 1 As shown, the automated sewage treatment device includes a device body 1, a lifting pump 2, a membrane assembly 3, an aeration assembly 4, a fan 5, a water production pump 6, and a control assembly 7. A pretreatment tank 11, a reaction tank 12, an equipment compartment 13, and a clean water tank 14 are sequentially arranged in the device body 1. The lifting pump 2 is located in the pretreatment tank 11, and a water outlet of the lifting pump 2 is communicated with the reaction tank 12. The membrane assembly 3 and the aeration assembly 4 are located in the reaction tank 12. The membrane assembly 3 is communicated with a water inlet of the water production pump 6, and the aeration assembly 4 is communicated with an air outlet of the fan 5. The fan 5 and the water production pump 6 are located in the equipment compartment 13, and a water outlet of the water production pump 6 is communicated with the clean water tank 14. The control assembly 7 is electrically connected to the membrane assembly 3 and the fan 5.

[0040] The device body 1 is the installation base of each component. The sewage is first stored in the pretreatment tank 11 to prevent the flow of sewage from being unstable and affecting the treatment effect. The sewage is then input into the reaction tank 12 through the lifting pump 2 placed at the bottom of the pretreatment tank 11. The reaction tank 12 is used to treat the sewage and degrade and decompose the organic matter in the sewage through the action of microorganisms. After the sewage undergoes biological reaction, it is sent into the membrane module 3 by applying appropriate pressure through the water production pump 6. The suspended matter, organic matter and microorganisms in the sewage are effectively intercepted by the membrane module 3, and the clean water is pumped into the clean water tank 14 through the water production pump 6. The air is collected, and the fan 5 provides gas for the aeration component 4. The fan 5 is started to introduce the high-pressure gas into the aeration component 4. The aeration component 4 evenly distributes the gas to the membrane component 3, providing sufficient oxygen for the microorganisms in the reaction tank 12, accelerating the reaction, and the rise of bubbles can drive the water flow, and the flow of water can play a certain cleaning role on the membrane component 3, preventing sludge from being deposited on the membrane component 3 and affecting the flux of the membrane component 3. The equipment compartment 13 provides a stable working environment for the fan 5, the water production pump 6 and the control component 7. The control component 7 automatically controls the actions of each component to realize the automatic operation of the device.

[0041] like Figure 1 , Figure 2 As shown, a water inlet pipe 111 is provided at one side of the pretreatment tank 11 , a grille 1111 is provided inside the water inlet pipe 111 , and a drain valve 141 is provided at one side of the clean water tank 14 .

[0042] Sewage enters the pretreatment tank 11 through the water inlet pipe 111. A grille 1111 is set in the water inlet pipe 111 to screen out large-volume debris in the sewage to prevent clogging by the debris. The treated sewage is placed in the clean water tank 14. When needed, the drain valve 141 can be opened to discharge the treated sewage for reuse.

[0043] like Figure 3 , Figure 4 As shown, the aeration assembly 4 includes an aeration frame 41 and an aeration pipe 42. The aeration frame 41 is placed in the reaction tank 12. The aeration pipe 42 is fastened to the aeration frame 41. The aeration pipe 42 is connected to the air outlet of the fan 5. The air outlet of the aeration pipe 42 faces the membrane assembly 3. The membrane assembly 3 is placed above the aeration frame 41.

[0044] The aeration frame 41 provides an installation basis for the aeration pipe 42. The aeration pipe 42 is provided with a plurality of air outlets. The fan 5 is started to transport the gas into the aeration pipe 42 and discharge it through the air outlets. The plurality of air outlets can increase the aeration rate, accelerate the dissolution of oxygen, provide sufficient oxygen for the microorganisms in the reaction tank 12, and accelerate the decomposition of sewage. The aeration component 4 is arranged directly below the membrane component 3. Aeration will generate air agitation, and the sewage will flow upward with the airflow, generating shear force on the surface of the membrane component 3, avoiding sludge deposition on the surface, thereby reducing pollution.

[0045] like Figure 3 , Figure 5 As shown, the membrane assembly 3 includes a hollow diaphragm 31, a membrane frame 32, a plastic bracket 33, and an electrode plate 34. The hollow diaphragm 31 is firmly connected to the membrane frame 32, the hollow diaphragm 31 is connected to the water inlet of the water production pump 6, and the electrode plate 34 is fixed on both sides of the membrane frame 32 through the plastic bracket 33.

[0046] The membrane frame 32 provides an installation base for the hollow diaphragm 31. Several groups of hollow diaphragms 31 are arranged on the membrane frame 32. The hollow diaphragm 31 uses a microporous membrane, which can effectively prevent the passage of suspended matter, bacteria, viruses and other microorganisms, thereby achieving efficient solid-liquid separation. After being treated in the pretreatment tank 11, the sewage reaches the reaction tank 12 and flows evenly from the surrounding to the surface of the hollow diaphragm 31. Through the negative pressure suction of the water production pump 6, the activated sludge and other substances in the sewage are separated by the hollow diaphragm 31, and the produced water flows from the surface of the hollow diaphragm 31 to the inside and is pumped into the clean water tank 14 through the water production pump 6. The plastic bracket 33 is fixed on the membrane frame 32 to provide support for the electrode plate 34.

[0047] like Figure 5 , Figure 6As shown, the electrode plate 34 is made of carbon felt and is provided with honeycomb holes. A conductive rod 321 is provided in the membrane frame 32 and is electrically connected to the electrode plate 34. The electrode plate 34 is inoculated with electrogenic bacteria and the conductive rod 321 is made of stainless steel.

[0048] By setting honeycomb-shaped holes on the electrode plate 34, not only can the fluidity of the sewage be ensured, but also the area of ​​the electrode plate 34 can be increased, providing a suitable living environment for the electrogenic bacteria. The treated sewage contains a large amount of organic matter, which provides nutrition for the electrogenic bacteria. The electrode plate 34 serves as the anode and the conductive rod 321 serves as the cathode. The electrogenic bacteria at the anode decompose the organic matter in the sewage into electrons and protons. The generated electrons then reach the cathode through the wire, and the protons reach the cathode through diffusion. Finally, under the action of the aeration component 4, the sewage at the conductive rod 321 contains a large amount of Oxygen is introduced, and a redox reaction occurs on the cathode. During the whole process, the substance and charge are conserved. In the external circuit, electrons flow continuously to form an electric current, thus forming a bioelectric field between the electrode plate 34 and the conductive rod 321. Under the stimulation of the electric field, not only the activity of microorganisms in the sewage can be improved, thereby improving the purification efficiency, but also because most of the sludge particles are negatively charged, they migrate away from the membrane surface due to the electrostatic repulsion in the electric field. At the same time, with the hydraulic shearing effect generated by aeration, the pollutants adsorbed on the membrane surface are more easily blown off, thereby achieving the effect of cleaning the membrane.

[0049] like Figure 7 As shown, the membrane assembly 3 also includes an arc-shaped shield 35 and an exhaust pipe 36 . The arc-shaped shield 35 is fastened to the membrane frame 32 . The arc-shaped shield 35 is located above the membrane frame 32 . The exhaust pipe 36 is connected to the arc-shaped shield 35 . The exhaust port of the exhaust pipe 36 extends out of the reaction tank 12 .

[0050] The aeration assembly 4 generates a large amount of gas when it is working. By installing an arc shield 35 on the membrane frame 32, the arc shield 35 is submerged in the sewage, and the gas generated by aeration can be collected. The bubbles generated by aeration gradually gather in the arc shield 35. After the gas in the arc shield 35 gathers to a certain extent, the pressure in the arc shield 35 increases and is discharged through the exhaust pipe 36. During the exhaust process, under the action of pressure, the gas will be quickly discharged through the exhaust pipe 36, and the sewage in the reaction tank 12 will quickly fill into the arc shield 35, and the flow of water will flush the membrane assembly 3 to play a cleaning role. The rapidly flowing sewage will impact the inner wall of the arc shield 35, generating a vibration, and transmitting the vibration to the membrane frame 32 to avoid sludge deposition on the membrane assembly 3. As the aeration proceeds, the cavity in the arc shield 35 will continuously circulate between gas collection and gas release, thereby continuously cleaning the membrane assembly 3 and improving the service life of the membrane assembly 3.

[0051] like Figure 7 , Figure 8 As shown, the exhaust pipe 36 includes a pipe body 361 , a first spring 362 , and a first slider 363 . The first spring 362 is fixedly connected to the pipe body 361 , and the first slider 363 is slidably connected to the pipe body 361 .

[0052] The first slider 363 closes the air outlet of the exhaust pipe 36 under the action of its own gravity and the elastic force of the first spring 362. As aeration proceeds, the pressure in the arc-shaped protective cover 35 gradually increases, thereby giving a thrust to the first slider 363, thereby overcoming the elastic force of the first spring 362, opening the air outlet of the exhaust pipe 36, and exhausting the gas. The first slider 363 automatically opens and closes the air outlet of the exhaust pipe 36 according to the pressure in the arc-shaped protective cover 35, thereby realizing automatic control of the exhaust.

[0053] like Fig. 9 As shown, the control component 7 includes a protective shell 71, an iron core 72, a coil 73, a second slider 74, a second spring 75, a rotating rod 76, and a wire 77. The protective shell 71 is tightly connected to the equipment compartment 13, the iron core 72 is tightly connected to the protective shell 71, the coil 73 is wound on the iron core 72, the negative pole of the coil 73 is connected to the electrode plate 34, the positive pole of the coil 73 is connected to the conductive rod 321, a sliding cavity 711 is provided in the protective shell 71, the second slider 74 is slidingly connected to the sliding cavity 711, the rotating rod 76 is hinged to the wire 77, the lower end of the second spring 75 is tightly connected to the protective shell 71, the upper end of the second spring 75 is tightly connected to the rotating rod 76, and the wire 77 is electrically connected to the lift pump 2.

[0054] By conducting the current generated by the electrogenic bacteria on the electrode plate 34 to the coil 73, since the coil 73 is wound around the iron core 72, a simple electromagnet is formed, and the second slider 74 is made of iron material, so when the coil 73 is energized, under the attraction of the magnetic force, the second slider 74 will overcome its own gravity and slide upward along the sliding cavity 711 away from the rotating rod 76. When the current decreases, it indicates that the nutrients required by the electrogenic bacteria are insufficient, and new sewage needs to be introduced from the pretreatment tank 11 to supplement the organic matter in the reaction tank 12, and the electricity As the flow decreases, the magnetic force generated by the coil 73 and the iron core 72 will become smaller, and the second slider 74 will slide downward along the sliding cavity 711 under the influence of its own gravity, and abut against the rotating rod 76, thereby compressing the second spring 75, so that the rotating rod 76 is connected to the wire 77, thereby giving an electrical signal to the lift pump 2, automatically starting the lift pump 2 to pump the sewage into the reaction tank 12, and after the electric bacteria are supplemented with organic matter, the current generated will increase, and the second slider 74 will move upward under the action of the magnetic force, disconnect the wire 77, and automatically shut down the lift pump 2.

[0055] The working principle of the present invention is as follows: the sewage is first stored in the pretreatment tank 11, and the sewage is input into the reaction tank 12 through the lifting pump 2 placed at the bottom of the pretreatment tank 11. The reaction tank 12 is used to treat the sewage, and the organic matter in the sewage is degraded and decomposed by the action of microorganisms. The fan 5 provides gas for the aeration component 4, and introduces the gas into the aeration component 4. The aeration component 4 evenly distributes the gas on the membrane component 3, and provides sufficient oxygen for the microorganisms in the reaction tank 12. The gas is sent into the membrane component 3 by applying appropriate pressure through the water production pump 6. The suspended matter, organic matter and microorganisms in the sewage are effectively intercepted by the membrane component 3. By inoculating electrogenic bacteria on the electrode plate 34 and cooperating with the conductive rod 321, a bioelectric field is formed on the membrane component 3 to improve the activity of microorganisms in the sewage, and the sludge particles migrate away from the membrane surface under the electrostatic repulsion. At the same time, with the hydraulic shearing effect generated by aeration, the pollutants adsorbed on the membrane surface are more easily blown off, and the clean water is pumped into the clean water tank 14 through the water production pump 6 for collection and reuse.
