250LPH EDI and RO system ultra pure water deionized water plant
Function and application
EDI is a cost effective, environmentally friendly alternative to conventional post-RO ion ex-changer applications in high purity water treatment.
Electro-deionisation (EDI) is a continuous deionization process combining electrodialysis (ED) and ion-exchange(IE) membranes and resins for producing ultra pure water.
