What are the advantages of laboratory EDI ultrapure water machine? EDI, also known as continuous electrodeionization, packed bed electrodialysis, or electrodesalination, is widely used in pure water and ultra pure water equipment. By using electrodialysis and ion exchange technologies, selective permeation of anions and cations is achieved, and ion migration is directed under the action of a current electric field to complete the removal of ions in water. Compared with traditional resin exchange, EDI electrodesalination technology can also regenerate ion exchange resins for hydrogen and oxygen ions, with the characteristic of continuous use, thus eliminating the problem of acid alkali chemical regeneration of ion exchange resins.

The advantages of EDI ultra pure water machine

1. It can significantly improve the desalination rate of pure water systems;

2. The water quality of the produced water is high and stable;

3. The operation and maintenance are simple and convenient. Compared to the frequent replacement of traditional ion exchange columns and regular acid-base regeneration of influent water, the EDI module in the laboratory EDI ultrapure water machine can last for 3-5 years without the need for module replacement;

4. Low operating cost, due to the long service life of the EDI module and the absence of acid-base regeneration, there is almost no need to replace purification system consumables within 3-5 years;

Characteristics of laboratory EDI ultrapure water machine

1. The EDI module significantly improves the desalination rate of the laboratory EDI ultrapure water machine through electrolyte ion migration;

2. Carbon bead technology has been added to the EDI module to reduce the pH value on the cathode side in alkaline environments, thereby reducing the risk of scaling;

3. By using ion exchange membrane technology, various ions can be directed and removed through the action of the electric field, which can greatly improve the ion removal rate;
