EDI is a continuous electro-chemical process of water purification where ion specific membranes, mixed bed resin, and a DC voltage across them, replace the standard acid- caustic chemical regeneration process.

An EDI unit after an RO unit, effectively replaces chemically regenerated deionizer without the chemicals, regeneration steps and associated labor.
Membranes and electricity replace chemicals and frequent regeneration
EDI units are mechanically simple when compared to typical regenerable ion exchange systems.
EDI units are in Continuous operation 24/7 with no halts for deionizer regeneration.
EDI eliminates all hazardous acid and caustic wastewater neutralization required by chemical deionizer regeneration which result in large excesses of salts to drain.
As a result of pending workplace and security legislation involving employer liability, more demanding rigorous safety, security and handling protocols will be required that will make chemical-based deionizers more expensive to operate. EDI eliminates this problem.
