EDI ultrapure water system deionization technology

EDI technology combines two mature Water Treatment technologies - electrodialysis technology and ion exchange technology. my country calls this packed bed electrodialysis or electrodeionization technology. It mainly replaces the traditional ion exchange mixed bed to produce high-purity water.

It can be expected that this water treatment product will become the mainstream equipment in the preparation of high-purity water projects in this century. The application of this technology and related technologies will bring about some fundamental changes in the original water treatment technology, thereby achieving better environmental protection and economic benefits. In the ultraPure Water of the EDI equipment, the following points must be guaranteed for the operation of the EDI (6 "ensure"):

1. Ensure that the operating current is within the specified range;

2. Ensure that the inlet water quality meets the requirements;

3. Ensure that the inlet pressure is within the specified upper limit;

4. Ensure that the inlet flow rate, especially the extreme water flow rate, is not lower than the requirements;

5. Ensure that the inlet pressure of fresh water, concentrated water and extreme water decreases;

6. Ensure that the recovery rate requirements of the membrane stack are not exceeded; Picture
