Daico Electrodeionization (EDI) is the answer in demanding applications that require consistent and economical removal of water impurities without the use of hazardous chemicals.
EDI is a continuous process for producing high-purity water using ion-exchange membranes, resins and electricity. Direct current (DC) is the driving force for removing ionized and ionizable species from the feed stream, while continuously regenerating the resin pack. Basically, EDI is an electrodialysis (ED) process modified by the addition of ion-exchange resin.
EDI, in combination with reverse osmosis as pretreatment, strips away more than 99.9% of feedwater ions, significantly outperforming both double-pass RO and straight DI. With lower chemical, energy and labor costs, Daico's state-of-the-art EDI technology is helping meet industry’s ultrapure water needs today and well into the 21st century.
