- Electro-Deionization Process



The Electro-deionization process uses electric current to treat (polish) deionized water from RO systems etc., to ultra-pure standards required for many critical applications. EDI’s will replace the conventional Mixed Bed Polishers and provide several advantages including: Lower capital and installation costs. Easier to maintain. No regenerations required. No handling of harsh chemicals. Smaller footprint.

WATERTRAK offers a wide range of sizes, materials of construction and configurations to meet all of your EDI water needs. Aquatech FEDI water units are salt free and do not require external salt dosing. They can be ordered either as a stand-alone unit or integrated into the most complex of deionized water control systems.
