Electrodization EDI Module
Working principle
EDI(Electrodization) is a membrane separation technology which combines electrodialysis and ion exchange technology, including anion exchange membrane and ion exchange membrane.Switching resin and DC power supply lamp equipment to realize water under the action of electric field through the selection of ion exchange membrane and resin exchange of ions Directional migration of ions to remove salt in water depth and to exchange ion exchange resin for two consecutive years through H and OH produced by water electrolysis. Prod action of Super pure water up to 15-18.2 Omega cm.
Product characteristics
Using the technology of middle partition full fill, good water quality
It is easy to operate without salt and heavy water circulation
Excellent electrical performance, high current efficiency, low voltage, low energy consumption
Line the lines side by side, two entry and two out of standard thread excuse, easy to install
Perfect structural design to ensure zero leakage
Product application
Boiler feed water for power, chemical and metallurgical industries
Super pure water for electronics, semiconductors and precision machinery
Water for chemical processes
Medical water
Ultrapure lab water
