Electro-de-ionization (EDI)

Process of Electrodeionization

The EDI design combines two well-established water purification technologies electrodialysis and ion-exchange resin deionization.

Through this revolutionary technique, dissolved salts can be removed with low energy cost and without the need for chemical regeneration; the result is high-quality pure water of multi-M_.cm resistivity which can be produced continuously at substantial flow rates.

EDI removes ions from water by forcing them out of the feed stream into adjacent streams via an electric potential. The resins operate in steady state; they act not as an ion reservoir but as an ion conduit.

Benefits of EDI

We provide EDI Systems from 50 Liters/hr to 200 m3/hr with Multiple Unit Arrays. EDI Systems are provided complete with DC power supplies, instrumentation for flow, conductivity, pH, TOC, etc. And complete automation with PLC / SKADA and intigration with up-stream / down-stream equipments.
