FEATURES & ADVANTAGES
1. What is EDI?
EDI water purification system is also called electrodeionization. It’s skillfully combined electroosmosis technology with ion exchange technology. By means of the selectivity permeation effect on anion and cation by anion and cation exchange membrane, and exchange effect on ion by ion exchange resin. Under direct-current electric field, realize the directed migration of ions, thus complete heavily salt removing, meanwhile, hydrogen ion and hydroxyl ion generated by water electrodeionization will make the ion exchange resin regeneration, so it can produce ultrapure water continuously without acid-base chemical regeneration.
2. EDI technology advantages
1). High efficiency produce ultrapure water, stabilization of water quality
2). Witout acid-base regenerant, low cost of operation
3). Work continuously, no need to stop because of regeneration
4). Operator avoid to touch with acid-base, apply safely and reliably.
5). Equipment structure compact, small occupied space, easy for installation
6). Easily realize full automatic control, easy for operation, low failure rate.
7). No regenerated water discharge, accord with environmental care requirement
3. EDI product application
EDI is more and more widely used in semiconductor, micro-electronics, power generating industry, pharmaceuticals industy, fine chemical engineering etc. area.
