EDI Plant

Electrodeionization (EDI) is a continuous, chemical-free process of removing ionized and ionizable species from feedwater using DC power. EDI is typically used to polish reverse osmosis (RO) permeate, and is a smart alternative to — and effective replacement of — conventional mixed bed ion exchange (IX). The Electrodeionization (EDI) Water System. This is a high water purifying production method which combines membrane separation and ion exchange processes. The process combines semi-impermeable membrane and ion exchange media technology which enable high-efficiency demineralization process.
