RO Water Treatment System Ultra-Pure Water EDI Water Treatment For Pharmaceutical

Technical Specifications of EDI Water Treatment Plant

EDI Water Treatment Plant Working Principle

In the EDI membrane block, a certain number of EDI units are separated by grids to form a concentrated water chamber and a fresh water chamber. In turn, negative/positive electrodes are provided at both ends of the cell. Driven by direct current, the anions and cations in the water flow through the fresh water chamber migrate to the concentrated water chamber through the anion and cation exchange membrane respectively and are removed in the fresh water chamber.

The Main Reasons for EDI Water Treatment Plant

1. The EDI membrane block runs at high current for a long time, and the accumulated heat cannot be dissipated, causing the EDI to be close to the two poles.
The diaphragm is heated and deformed, the pressure difference of the EDI concentrated water increases, and the water quality and water volume decrease to varying degrees.
2. If the EDI membrane block is not cleaned and maintained for a long time, it will cause calcium and magnesium scale on the EDI membrane and channel, which will make the
The water pressure difference increases, resulting in a decrease in the quality of the produced water and an increase in the voltage, which in turn makes the current unable to be adjusted.
ultimately unusable.
3. The use of unreasonable cleaning and disinfection agents will directly lead to damage and fragmentation of EDI resin, and water in and out.
The pressure difference increases, resulting in a decrease in the quality and quantity of the produced water. 4. The EDI system is powered on under water shortage
It directly leads to the heating and burning of the diaphragm and resin, and the cleaning is invalid and cannot be used.
5. There is no security filter before the EDI enters the water, which directly causes foreign matter to block the EDI channel, and the pressure difference between the inlet and outlet increases.
Caused a serious decline in the amount of water produced, cleaning is ineffective.
6. Poor pretreatment (softener, sodium bisulfite, RO, etc.), control system failure/failure (safety
full interlocks, low flow protection issues), improper system design.
7. The residual chlorine in the EDI water exceeds the standard, resulting in the oxidation of the resin of the EDI membrane block and the oxidation of the diaphragm. Increased differential pressure, flux decline, water quality declines.

Daily Maintenance of EDI Water Treatment Plant

1. The personnel who operate the industrial EDI ultrapure water treatment equipment must switch the equipment on and off strictly according to the operation process, and the operator needs to inspect the equipment at least three times a day to ensure the normal operation of the ultrapure water equipment. .
2. The operator should do more than 2 patrol inspections every day to ensure the normal operation of the equipment.
3. Operators and maintenance personnel should always pay attention to keeping the equipment clean and tidy, eliminate dripping and leakage problems in time, and make records for problems that cannot be solved in time, and must be solved after research.
4. All joints and water pipes of industrial EDI ultra-pure water treatment equipment should be checked regularly, such as whether there is looseness or damage, etc., and the operation of high-pressure pumps and water pumps should also be checked regularly. Pay attention to Freeze-proof.
5. Regularly replace the filter screen and PP cotton of the industrial EDI ultra-pure water treatment equipment to ensure that the water treatment standard is within the range.
6. Regularly check the operation of the water pump and high-pressure pump, and report any problems in time.
7. If the operator finds that the equipment is abnormal, he should immediately find out the reason and report it in time.
8. Always check whether the connector of the electric control box is off or disconnected, and ensure the safety of electricity use.
