EDI, also called electric desalination is a new ultra pure water technology which gradually developed in the 20th century, which combines electric dialysis technology and ions exchange technology. It is using the selectivity penerate function of anion and cation membrane and exchange function of ions exchange resin, under direct current electric field to make ion directed migration. Finally to make deep desalination of water. In the same time, hydrogen ion and hydroxide ion which produced when water ionized will regeneration, and it can produce ultra pure water continuously.
EDI equipment is applied after the reverse osmosis system to replace the traditional mixed bed ion exchange technology (MB-DI) to produce stable ultrapure water. Compared with mixed ion exchange technology, EDI technology has the following advantages:
1. Stable water quality
2. Easy to realize fully automatic control
3. No shutdown due to regeneration
4. No need for chemical regeneration
5. Low operating cost
6. Small plant area
