Summary of issues with ultra pure water EDI equipment

Since its introduction to the market, ultra-pure water EDI equipment has replaced traditional ion exchange water treatment technology to meet the needs of modern industry and environmental protection. Therefore, when EDI in pure water equipment encounters problems and damages, it will inevitably affect the normal production of enterprises and increase the operating costs of the company.

Summary of the causes of damage to ultra pure water EDI equipment;

1. The EDI membrane block operates under high current and below the rated flow rate for a long time, and the accumulated heat on the electrode plate side cannot be effectively dissipated, causing the membrane and partition net near the two poles of EDI to heat and deform first. The EDI concentrated water pressure difference increases, and the water quality and quantity decrease, leading to severe carbonization and leakage.

2. The EDI membrane block has not been cleaned and maintained for a long time, causing scaling on the EDI membrane and channels, increasing the difference in inlet and outlet water pressure, resulting in a decrease in the quality of the produced water, inability to adjust the current, and an increase in voltage.

3. Improper control of residual chlorine and other oxidants in the ultrafiltration system, resulting in excessive amount of EDI oxidant entering, resulting in the breakage of EDI resin, blockage of the production water channel, and a decrease in water volume.

4. Improper cleaning and disinfection directly leads to the breakage of EDI resin, an increase in the pressure difference between inlet and outlet, and a decrease in both the quality and quantity of produced water.

5. When the EDI system is manually running, powering up in a water shortage state directly leads to the heating and carbonization of the membrane and resin, making cleaning ineffective and unusable.

6. There is no safety filter before the EDI enters the water, or the pipeline and water tank are not thoroughly cleaned during installation, resulting in foreign objects blocking the EDI channel, increasing the water pressure difference between the inlet and outlet, causing a serious decrease in the production water volume and ineffective cleaning.

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

8. The system process design was improper and did not meet the conditions for EDI use.

9. Improper system maintenance and management, failure to comply with EDI usage conditions.

So in order to ensure the normal operation of EDI ultra pure water equipment and not affect the production progress of the enterprise, please be cautious and operate the equipment according to the equipment instructions.
