The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A water treatment apparatus and a water producing apparatus according to an embodiment of the present invention will be described with reference to fig. 1 to 6.

Fig. 1 is a schematic structural view of a water treatment apparatus according to an embodiment of the present invention.

As shown in fig. 1, the water treatment apparatus 100 includes: water inlet 1, delivery port 2, water treatment component 3, washing subassembly 4 and control assembly 5. The water treatment component 3 is respectively connected with the water inlet 1 and the water outlet 2 and is used for treating water entering from the water inlet 1 and outputting the treated water from the water outlet; the cleaning component 4 is arranged corresponding to the water treatment component 3 and is used for cleaning the water treatment component 3 so as to wash away scale on the water treatment component 3.

In this embodiment, the control module 5 is configured to control the water treatment module 3 to perform electrolysis and/or bubble treatment on the inlet water through the water treatment module 3 in a water use state (i.e., when a user has a demand for water), and to control the water treatment module 3 and the cleaning module 4 to perform cleaning on the water treatment module 3 in a cleaning state.

Specifically, the water inlet 1 can be accessed with city tap water, and the water treatment device 100 is used for treating the tap water to obtain acidic electrolyzed water, bubble acidic electrolyzed water and the like required by a user. A water outlet switch (such as a faucet, a water outlet button and the like) can be arranged corresponding to the water outlet 2, when the water outlet switch is turned on, an electric signal can be sent to the control assembly 5, and then the control assembly 5 can detect the water demand of a user; the control component 5 also detects whether the user has the water demand through the flow sensor S arranged on the pipeline connected with the water outlet 2, if the flow sensor S detects that the water flow is greater than a certain value, the control component 5 can determine that the water outlet switch is opened, and the user has the water demand. At this time, the water demand can be defaulted as the electrolyzed water demand, and the control module 5 can control the water treatment module 3 to electrolyze the inlet water entering the water treatment module 3 to generate the acidic electrolyzed water. Wherein, the acidic electrolyzed water can be used for washing face to effectively protect skin, keep moisture of skin for a long time and prevent skin aging; the cleaning agent can also be used in food processing industry, such as cleaning fruits and vegetables, so as to realize sterilization and fresh keeping of the fruits and vegetables, and further guarantee the quality and the nutritive value of the fruits and vegetables; and can also be used for cleaning kitchenware, such as dishes, so as to realize sterilization of the dishes and further ensure the cleaning effect of the dishes.

Further, after the water supply is finished, the control module 5 may determine the current operation condition of the water treatment module 3 to determine whether to clean the water treatment module 3. For example, it is determined that the water treatment module 3 needs to be cleaned by detecting that the water treatment module 3 is continuously operated for a preset time, and at this time, the control module 5 may control the water treatment module 3 and the cleaning module 4 to operate, so as to clean the water treatment module 3 through the cleaning module 4, and discharge the cleaning wastewater through the wastewater outlet 22 in the water outlet 2, wherein the preset time may be calibrated according to the water treatment capacity of the water treatment module 3, such as 24 hours, 36 hours, and so on. Optionally, the cleaning may be performed after the end of each large amount of water usage, and if it is detected that the current continuous water usage reaches a preset value (which may be calibrated according to the water treatment capacity of the water treatment assembly 3), the cleaning is started after the end of the current water usage.

As an example, a water usage selection option may be set for the water treatment module 3, and the water usage selection option may be set in the form of a field switch or a virtual switch of a terminal device. When the user uses water, the user can select the water using requirement such as the electrolytic water requirement, the bubble acid electrolytic water requirement, the electrolytic water level requirement, the cleaning requirement and the like through the water using selection option, and then the control assembly 5 can control the corresponding assembly according to each requirement to realize the corresponding requirement. Wherein, terminal equipment can with control assembly 5 communication connection, like wifi communication connection, bluetooth communication connection etc. terminal equipment can realize long-range controlling water treatment facilities 100.

From this, this water treatment facilities 100 can realize the electrolytic treatment and/or the bubble of intaking through water treatment component 3 and handle, satisfies the demand of user's acid electrolysis water, acid bubble electrolysis water etc. and through the setting of washing subassembly 4, can realize the washing to water treatment component 3, prolongs water treatment component 3's life-span to better satisfy user's water demand

In one embodiment of the present invention, referring to fig. 2, the water treatment assembly 3 comprises: saline solution tank 31, electrolysis member 32, water pump 33, water route switching module 34.

The saline solution tank 31 has a tank structure and can be used for storing saline solution, such as sodium chloride solution. The electrolytic element 32 is used for electrolyzing water flowing into the electrolytic element 32 after applying current to generate acidic electrolyzed water, wherein the cleaning assembly 4 can be arranged corresponding to the electrolytic element 32. The water pump 33 is connected to the water passage of the water treatment unit 3 to pump water by pressurization to promote the circulation of the water passage. The waterway switching component 34 is respectively connected with the water inlet 1, the water outlet 2, the saline solution tank 31, the electrolytic component 32 and the water pump 33, and is used for realizing the switching of the waterway of the water treatment component 3.

Specifically, the electrolytic element 32 may be provided with at least one pair of electrolytic sheets, and the pair of electrolytic sheets are respectively connected to the positive and negative electrodes of the power supply, and can electrolyze the sodium chloride solution in the saline solution tank 31 in the energized state, thereby generating the required disinfectant solution with hypochlorite. The electrolytic sheet is made of a titanium material with extremely inertia and corrosion resistance, and then a thin coating layer made of ruthenium and iridium materials with more inertia and corrosion resistance is covered on the outer layer of the titanium electrolytic sheet, so that the problem of corrosion failure caused by the use of other metal materials (such as stainless steel, copper and the like) in the electrolytic sheet can be effectively reduced or even avoided. The control component 5 can be used for controlling the waterway switching component 34 and the water pump 33 in a water using state, and controlling a power supply applied to the electrolytic component 32, so that the power supply generates corresponding current to be applied to the electrolytic module, and further realizing the electrolytic treatment of the inlet water to generate acidic electrolyzed water; and in the cleaning state, the water path switching assembly 34 is controlled to be switched to a corresponding water path, and the water pump 33 and the cleaning assembly 4 are controlled to start to work so as to clean the electrolytic component 32.

In this embodiment, as an example, referring to fig. 2, the water outlet 2 may include a water using port 21 for outputting water required by a user and a waste water port 22 for outputting waste water generated by washing. The saline solution tank 31 may include a first port 311 disposed above the saline solution tank 31, a second port 312 and a third port 313 disposed below the saline solution tank 31, and the waterway switching assembly 34 may include six solenoid valves, which are respectively denoted as a first solenoid valve 341, a second solenoid valve 342, a third solenoid valve 343, a fourth solenoid valve 344, a fifth solenoid valve 345 and a sixth solenoid valve 346.

Wherein, a water outlet switch, such as a water tap, is correspondingly arranged at the water using port 21 for realizing water taking of a user; the waste water port 22 may be connected to a waste water tank for recovering the washing waste water. One end of the first solenoid valve 341 is connected to the first port 311, and the other end thereof can be communicated with the outside atmosphere; one end of the second electromagnetic valve 342 is connected with the water inlet 1, and the other end is connected with the first inlet of the electrolytic element 32; one end of the third electromagnetic valve 343 is connected to the second port 312, and the other end is connected to the inlet of the water pump 33; one end of the fourth solenoid valve 344 is connected to the third port 313, and the other end is connected to the first outlet of the electrolytic element 32, wherein the second outlet of the electrolytic element 32 is connected to the water using port 21 for outputting acidic electrolyzed water; one end of the fifth electromagnetic valve 345 is connected with the outlet of the water pump 33, and the other end is connected with the second inlet of the electrolytic element 32; one end of the sixth solenoid valve 346 is connected to the fifth solenoid valve 345, and the other end is connected to the waste water port 22.

In this example, referring to fig. 2, 5, the control assembly 5 may be configured to: upon detecting the demand for electrolyzed water, at this time, the user may perform only the operation of opening the faucet, control the second, third, fourth, and

fifth solenoid valves

342, 343, 344, and 345 to be opened, and control the water pump 33 to be activated and apply power to the electrolytic member 32. After the water pump 33 is controlled to be started, the water cup 33 can be controlled to rotate at a preset rotating speed; the power supply to the electrolytic element 32 may be applied with a preset current, or with a current adapted to the current quality of the incoming water, and may be provided independently of the control unit 5 or may be provided integrally with the control unit 5.

Alternatively, referring to fig. 2, the water treatment apparatus 100 may further include: a first detector 6. The first detector 6 is connected to the control unit 5, and can be disposed on the pipeline between the fifth solenoid valve 345 and the second inlet of the electrolytic element 32, and can contact the saline solution in the pipeline for detecting the water quality of the saline solution to obtain a water quality detection value, for example, the first detector 6 is a TDS detector for detecting the total dissolved solids TDS value. The control component 5 is further configured to determine a control parameter (e.g., an electrolysis current) of the power applied to the electrolysis element 32 according to the detected water quality value, and control the power applied to the electrolysis element 32 according to the control parameter when the water treatment apparatus 100 is in a water-using state, such as causing the power to generate the electrolysis current. For example, the control unit 5 may store a correspondence relationship between the water quality detection value and the electrolytic current in advance, and the correspondence relationship may be stored in a table format, so that the electrolytic current corresponding to the detected water quality detection value may be obtained by looking up the table.

Wherein, the TDS value is the water quality testing index who sets up specially to the pure water, and the TDS value represents the total solid content of soluble in the aquatic. One cannot visually understand the purity of drinking water, which appears to be clear and transparent water, which may contain many impurities. The TDS value can reflect the water quality to a certain degree, and generally, the lower the TDS value is, the less soluble salts such as heavy metal ions in the water are, and the purer the water quality is.

Referring to fig. 2, 5, the control assembly 5 may also be used to: after the end of water use (e.g., the water tap is closed) is detected, all the solenoid valves are controlled to be closed, the water pump 33 is controlled to stop running, and the power supply to the electrolytic member 32 is controlled to be closed. When the water consumption is detected to be finished, such as the water tap is closed, and the water consumption (which can be the accumulated water consumption) reaches a preset water amount, such as 48L, the water pump 33 is controlled to be started, such as to run at a preset rotation speed, and the first solenoid valve 341, the third solenoid valve 343 and the sixth solenoid valve 346 are controlled to be opened, so as to discharge the wastewater in the saline solution water tank 31 from the wastewater outlet 22, wherein the preset water amount can be calibrated according to the treatment capacity of the water treatment assembly 3, such as 48L. Further, when the water level in the saline solution tank 31 is detected to be lowered to the first preset water level, the first solenoid valve 341, the third solenoid valve 343, the sixth solenoid valve 346 and the water pump 33 are controlled to be closed, so that the water treatment apparatus 100 enters a standby state.

Wherein, the water consumption can be detected by a flow sensor S arranged on a water path connected with the water consumption port 21. Specifically, the water flow can be measured through the flow sensor S, the water consumption can be further calculated according to the water flow and the water consumption time, and the water consumption can be continuously recorded after the last cleaning is finished until the water consumption is reset during cleaning. Optionally, the water treatment apparatus 100 may further include a display unit for displaying the current water consumption, and the user may determine whether to clean the water treatment apparatus according to the displayed water consumption. Therefore, user experience can be improved.

Specifically, referring to fig. 2 and 5, when a user wants to use electrolyzed water, the user only needs to open a faucet, the faucet generates an electric signal to inform the control assembly 5, the first detector 6 (such as a TDS sensor) detects the quality of the inlet water after adding salt, a power panel for supplying power to the electrolysis element 32 is controlled according to the water quality condition, and corresponding current (obtained by looking up a table) is generated, wherein the PH value of the generated acidic electrolyzed water is different from the PH value of the generated acidic electrolyzed water according to the current applied to the electrolysis element 32 under the same water quality condition, as shown in table 1 below. Then, the control unit 5 controls the

solenoid valves

342, 343, 344, 345 to be opened, and controls the water pump 33 to be started, and the flow sensor S provided on the pipe connected to the water port 21 may start recording the amount of the weakly acidic electrolyzed water used by the user. At this time, there are two water inlets, one is a tap water waterway, which enters the electrolytic element 32 through the second electromagnetic valve 342, and the other is a saline solution tank 31 waterway, which enters the electrolytic element 32 through the third electromagnetic valve 343, the water pump 33 and the fifth electromagnetic valve 345; and two paths of water are discharged, wherein one path of water is discharged through the flow sensor S, the other path of water enters the saline solution water tank 31 again through the fourth electromagnetic valve 344, and the water is weakly alkaline.

The faucet may be, for example, a hall faucet, i.e., a faucet including a hall switch, which sends an electric signal when turned on and stops sending an electric signal when turned off, so that the control assembly 5 determines the water usage state.

TABLE 1

As can be seen from table 1, when the TDS values of the salt solutions are the same, the higher the current applied to the electrolysis element 32, the higher the electrolysis capacity, and the more acidic the electrolyzed water generated by electrolysis, i.e., the lower the PH, the better the sterilization effect. The TDS value of salt solution is different, and is the same to the electric current that electrolytic element 32 applyed, and the TDS value of salt solution is the bigger, and electrolytic capacity is stronger, and the electrolysis water's that the electrolysis produced acidity is stronger, and pH value is less promptly, and bactericidal effect is better.

When the water is used, the user turns off the faucet, which stops sending electrical signals to the control assembly 5. At this point, the control module 5 may detect the continuous cumulative water usage recorded by the flow sensor S. When it is detected that the electrolyzed water having a predetermined water amount of, for example, 48L has been used, the wastewater in the saline solution tank 31 may be discharged, and at this time, in the standby state, the

electromagnetic valves

341, 343, and 346 and the water pump 33 are opened, and the wastewater in the saline solution tank 31 is discharged from the wastewater outlet 22, and when the low water level sensor of the saline solution tank 31 detects a signal (i.e., the water level drops to the first predetermined water level), the

electromagnetic valves

341, 343, and 346 and the water pump 33 are closed, and at the same time, the record value of the flow sensor S may be cleared, or the flow sensor S may be caused to enter the next recording period.

Referring to fig. 2, 5, the control assembly 5 may also be used to: when a cleaning requirement is detected, if a user applies a cleaning instruction, the continuous water treatment time reaches the preset time and the like, the cleaning component 4 is controlled to be started if the component capable of performing ultrasonic cleaning is started, and meanwhile, the second electromagnetic valve 342, the fifth electromagnetic valve 345 and the sixth electromagnetic valve 346 are controlled to be opened and continuously kept for the preset time to form one-time cleaning, so that the service life of the electrolytic part 32 can be prolonged, the water requirement of the user can be better met, wherein the value of the preset time can be 1-5 min, such as 2 min.

Wherein the cleaning assembly 4 may comprise an ultrasonic assembly 41, see fig. 2, the ultrasonic assembly 41 may comprise: the plurality of ultrasonic probes, such as two ultrasonic probes, are denoted as a first ultrasonic probe 411 and a second ultrasonic probe 412. Wherein, all correspond electrolysis part 32 and set up in the below of electrolysis part 32, and first ultrasonic probe 411 and second ultrasonic probe 412 all are connected with control assembly 5, and are used for under control assembly 5's control, carry out ultrasonic cleaning to electrolysis part 32. When the ultrasonic assembly 41 includes three or more ultrasonic probes, the ultrasonic probes may be uniformly disposed below the electrolytic member 32 to generate uniform ultrasonic vibration, thereby improving the ultrasonic cleaning effect.

Specifically, during cleaning, the ultrasonic assembly 41 is energized, the energized ultrasonic assembly 41 converts power frequency electricity into high-frequency electric signals, and transmits the high-frequency electric signals to the ultrasonic probe, the ultrasonic probe converts the high-frequency electric signals into ultrasonic vibration, and the mechanical vibration is transmitted to the electrolytic element 32 under the action of the ultrasonic vibration, so that the liquid flowing into the electrolytic element 32 alternately generates vibration between density and density, the liquid is continuously stretched and compressed, the density part is stretched to form micro-bubbles, the micro-bubbles are continuously generated and continuously broken under the ultrasonic vibration, when the micro-bubbles are broken, the surrounding liquid stretches to the center of the bubbles from all directions at a huge speed, water hammer is generated to form up-and-down convection, and the electrolytic element 32 is ultrasonically cleaned, so that scale and the electrolytic element are quickly separated; the cleaning of the electrolytic elements 32 can be accomplished by a single cleaning with clean tap water, and the waste water resulting from the cleaning can be discharged through the waste water port 22, for example, into a dedicated waste water tank.

As shown in table 2 below, compared with the case of not performing ultrasonic cleaning, after the ultrasonic cleaning is performed by using the ultrasonic assembly of the present invention, the service life of the water treatment assembly 3 can be effectively prolonged, and the service life of the ultrasonic cleaning can be prolonged as the quality of the inlet water is better.

TABLE 2

Further, in an embodiment of the present invention, referring to fig. 3, the water treatment assembly 3 may further include: and a salting member 35. This add salt spare 35 corresponds salt solution water tank 31 and sets up, and it can adopt jar column structure, can be used to the storage salt solute to and dissolve the salt solute, wherein, the salt solute can be the sodium chloride solute. Alternatively, the saline solution may be added to the salting member 35 manually or automatically by a device, and the amount of saline solution added at each time may be the same, so as to better achieve a quantitative water use.

The waterway switching component 34 can also be connected with the salting component 35, so that the control component 5 can also control the waterway switching component 34, so that the salting component 35 applies the dissolved saline solution to the saline solution tank 31.

In this embodiment, referring to fig. 3, as an example, the waterway switching assembly 34 may further include: a seventh solenoid valve 347 and an eighth solenoid valve 348. One end of the seventh electromagnetic valve 347 is connected with the water inlet 1, and the other end of the seventh electromagnetic valve 347 is connected with an inlet of the salting component 35; one end of the eighth solenoid valve 348 is connected to the outlet of the salting member 35, and the other end is connected to the third port 313.

In this example, referring to fig. 3 and 5, the control module 5 is configured to, when it is detected that the salt adding process of the salt adding member 35 is finished, for example, the salt solution quality reaches a preset value, the salt adding is not detected for a certain period of time, and the like, control the first solenoid valve 341 connected to the first port 311 to be opened so that the air pressure in the salt solution water tank 31 is the same as the outside air pressure, and control the seventh solenoid valve 347 and the eighth solenoid valve 348 connected to the salt adding member 35 to be opened so that the salt solution is dissolved in the salt adding member 35, and inject the salt solution obtained by the dissolution into the salt solution water tank 31. As the saline solution is injected, the saline solution level in the saline solution tank 31 gradually rises, and when the water level in the saline solution tank 31 reaches the second preset water level, the control assembly 5 may control the first solenoid valve 341, the seventh solenoid valve 347 and the eighth solenoid valve 348 to be closed, so as to generate acidic electrolyzed water satisfying the demand. Wherein the second preset water level is greater than the first preset water level.

Alternatively, the second preset water level and the first preset water level may be detected by a water level sensor disposed at the aqueous solution tank 31, or may be detected by water level sensors disposed at corresponding positions above and below the saline solution tank 31.

Specifically, referring to fig. 3 and 5, since the salt content in the tap water is insufficient to generate enough hypochlorite ions, which are dissolved in the water to form weakly acidic water and have a certain sterilization and disinfection effect, the user may first manually add salt (e.g., sodium chloride) to the salting member 35 when using the water treatment apparatus 100. After the user adds salt, the

controllable solenoid valve

341, 347, 346 of control module 5 is opened, controls other solenoid valves and closes, and the water route is that the running water gets into for adding salt piece 35 through seventh solenoid valve 347, melts salt into salt water, through eighth solenoid valve 348, gets into salt solution water tank 31, and after high level water level sensor detected the signal, stop the water injection, the end electrolysis preparation stage, closed all solenoid valves. During water injection, the first solenoid valve 341 is opened to prevent water injection failure of the saline solution tank 31 caused by the pressure greater than the external atmospheric pressure.

Still further, in an embodiment of the present invention, referring to fig. 4, the water treatment module 3 may further include: and a gas entrainment assembly 36. The gas-adding component 36 is connected to the water path switching component 35, which can be disposed on the water outlet side of the electrolytic component 32, and is used for adding gas (such as carbon dioxide) into the acidic electrolyzed water generated by the electrolytic operation of the electrolytic component 32 to obtain the bubble acidic electrolyzed water.

Referring to fig. 4 and 5, the control module 5 is further configured to control the waterway switching module 34 and the aeration module 36 according to a requirement, so as to switch the water treatment module 3 to the aeration waterway and perform bubble treatment on the electrolyzed water, so as to generate the bubble acidic electrolyzed water.

In this embodiment, as an example, as shown in fig. 4, the waterway switching assembly 34 may further include: a ninth solenoid valve 349 and a tenth solenoid valve 3410. One end of the ninth electromagnetic valve 349 is connected with the second outlet of the electrolytic element 32, and the other end is connected with the inlet of the gas adding assembly 36; the tenth solenoid valve 3410 has one end connected to the outlet of the air entrainment assembly 36 and the other end connected to the water usage port 21.

In this example, referring to fig. 4 and 5, the control assembly 5 may further be configured to, when a demand for bubble electrolyzed water is detected, for example, a user sends a corresponding instruction through a terminal device, control the ninth electromagnetic valve 349 to open, so that the gas adding assembly 36 is communicated with the electrolytic part 32, so as to inject the electrolyzed water into the water tank of the gas adding assembly 36, and when the water level in the water tank reaches a third preset water level, such as full water, control the ninth electromagnetic valve 349 to close, control the gas adding part of the gas adding assembly 36 to inject gas into the water tank (at this time, the water tank may be sealed to ensure a gas injection effect), and when the injected gas reaches a preset gas amount (a value may be calibrated according to a capacity of the water tank in the gas adding assembly 36), control the ninth electromagnetic valve 349 and the tenth electromagnetic valve 3410 to open.

Specifically, referring to fig. 4 and 5, when the user wants to use the bubbles to electrolyze the weak acid water, the control module 5 may control the ninth electromagnetic valve 349 to open to inject the weak acid electrolyzed water into the water tank of the air entrainment module 36, when the water tank is full, the ninth electromagnetic valve 349 is closed, CO2 is injected into the water tank, and then the

electromagnetic valves

349 and 3410 are opened to form the bubble acid electrolyzed water together with the acid electrolyzed water in the water outlet path through the faucet, so as to increase the cleaning and sterilizing capability of the water output from the water treatment apparatus 100. After the use is finished. The control unit 5 may close all the solenoid valves, the power supply to the electrolyzer 32 and the water pump 33.

As one example, the water treatment device 100 may further include an electrodialysis module disposed between the water outlet side of the electrolysis element 32 and after the water is used. The electrodialysis module is provided with an electrodialysis membrane stack, can purify electrolyzed water through the electrodialysis membrane stack, can prepare purified water with adjustable TDS (total dissolved solids), and has the advantages of adjustable fresh water quality, high recovery rate, 90% of purified water outlet proportion and the like. An electrodialysis membrane stack (EDR) is an electrochemical water purification module consisting of an ion exchange membrane, a flow channel and electrodes, ions are driven by an electric field to move directionally, and are influenced by selective permeation of the ion exchange membrane to generate dense-dilute water separation. Under the action of an electric field, the orderly arrangement of the anion-cation exchange membranes divides the frequent reverse-electrode electrodialysis membrane stack into a purified water chamber and a concentrated water chamber in order. The water purification capacity of the EDR membrane stack is influenced by external voltage, and the target water quality can be controlled by adjusting the external voltage. In the operation process, the polarities of the positive electrode and the negative electrode of the electrodialysis membrane stack are mutually inverted at regular intervals, so that dirt formed on the surfaces of the ion exchange membrane and the electrodes can be automatically cleaned, and the long-term stability of the efficiency of the ion exchange membrane and the water quality and the water quantity of fresh water are ensured. When the electrodes are reversed, the polarities of the electrodes are exchanged, and the thick and thin chambers and the thick and thin water paths are also exchanged. It should be understood that "inverting" means that the polarities of the positive and negative electrodes are inverted once, for example, the electrodialysis membrane stack is provided with a first electrode and a second electrode, where the first electrode is a positive electrode and the second electrode is a negative electrode, and after inverting, the first electrode is a negative electrode and the second electrode is a positive electrode.

Specifically, traditional membrane separation processes are mainly pressure driven membrane processes, including microfiltration, ultrafiltration, nanofiltration and reverse osmosis, which generally have greater flux but lower rejection of small solutes; nanofiltration and reverse osmosis have higher rejection rate of small-molecular solutes, but face the problems of higher energy consumption, serious membrane pollution and the like. Compare in traditional pressure drive membrane process, through setting up the electrodialysis module, it is stable to utilize electric field force driven electrodialysis technique to go out the water velocity of flow to can make the pollutant desorption on membrane surface through the positive negative electrode that changes the electrodialysis, thereby reach the purpose that reduces the membrane pollution, be convenient for detach the incrustation scale in the electrodialysis module, improve the operational reliability and the stability of electrodialysis module, reach and prolong whole electrodialysis module life, this electrodialysis technique is called and is reversed the electrodialysis technique.
