50 ton/hour EDI high-purity water production device

150ton/hourEDIProcess description of high-purity water production equipment:

EDI technology is currently relatively advancedPreparation of ultrapure waterProcess, used to replace traditional mixed bed water treatment systems, can continuously and stably produce high-purity water,EDIThe advantage of this is that it does not require chemical agents for regeneration, so there is no need for chemical regeneration agent storage tanks and corresponding neutralization tanks, and there is no need to collect, store, and treat harmful chemical wastewaterEDIThis greatly simplified the system and saved labor.ROreverse osmosis membraneThe application has reduced the requirements for occupying large equipment sites and also lowered the cost of sewage treatmentEDIThe application of technology conforms to this point. due toEDIsystemSuitable design combinations can be made based on the actual situation on site to ensure that there are no high tanks in the equipment factory room（Mix Bed）Existence. When it comes to the requirement for complete sets of equipment to be quickly installed and put into operation, equipment using membrane systems has extremely significant advantages in this regard.

Another advantage is that,EDIThe discharged concentrated water only contains impurities from the incoming water, and the water quality of this type of water is usually better than that of the incoming water from the pretreatment system. Therefore, the concentrated water can be directly reused in the first stageROThe reverse osmosis water storage tank effectively eliminates the discharge of wastewater. On the contrary, the regeneration of the mixed bed is a one-time process. Due to the use of chemical agents to regenerate the ion exchange resin bed, the waste liquid contains more than usualEDIHigh concentration water3-4The waste ions are usually not recycled into the pre-treatment system, but discharged into the wastewater neutralization tank.Secondary reverse osmosisRO+EDIThe operation process is continuous, and the water quality produced is stable. Unlike mixed beds, the effluent quality is not affected by ion leakage at the beginning and end of each regeneration cycle. This simplifies the operation of continuous operation and eliminates the need for setting up operators to adjust related equipment for regeneration work.

III50ton/hourEDIIn high-purity water production equipmentEDIReason for membrane damage:

EDI membrane stackserve asHigh purity water equipmentOnce the main components are damaged, it will directly shorten the service life of the polishing mixed bed resin, increase operating costs, and seriously affect productionEDIThe reasons for the damage of the membrane block are as follows:

1EDIThe membrane block of ultrapure water equipment operates under high current and below rated flow conditions for a long time, and the heat accumulated on the electrode plate side cannot be effectively dissipated, resulting inEDIThe membrane and mesh of the ultrapure water equipment near the two poles first generate heat and deform, EDIThe increase in concentrated water pressure difference in ultrapure water equipment can lead to a decrease in water quality and quantity, and severe carbonization and water leakage.

2EDIThe membrane block of ultrapure water equipment has not been cleaned and maintained for a long time,EDIThe membrane and channel of ultrapure water equipment are scaled, causing an increase in the pressure difference between inlet and outlet water, resulting in a decrease in the quality of the produced water, inability to adjust the current, and an increase in voltage.

3. Activated carbon filtration system andSBSImproper control of residual chlorine and other oxidants by the reducing agent dosing device leads toEDIUltra pure water equipmentExcessive oxidant, resulting inEDIThe resin of the ultrapure water equipment is broken, blocking the water production channel and causing a decrease in water volume.

4. Improper cleaning and disinfection directly lead toEDIThe resin of the ultrapure water equipment is broken, causing an increase in the pressure difference between the inlet and outlet water, resulting in a complete decrease in the quality and quantity of the produced water.

5EDIWhen the ultrapure water equipment system is manually operated and powered on in a water deficient state, it directly causes the heating and carbonization of the membrane and resin, making cleaning ineffective and unusable.

6EDIThe ultra pure water equipment lacks a safety filter before entering the water, or the pipeline and water tank are not cleaned during installation, resulting in foreign object blockageEDIThe channel of ultrapure water equipment has an increased pressure difference between inlet and outlet, resulting in a serious decrease in water production and ineffective cleaning.

7. Current and voltage exceeding the rated value or human error.

8. Improper system process design, failure to achieveEDIThe usage conditions of water treatment equipment.

9. Improper system maintenance and management, failure to complyEDI highThe usage conditions of pure water equipment.
