Product Description:
EDI(continuous Electric-deionization) uses mixed ion exchange resin to adsorb the anion and cation ions in the feed water. Meantime, under direct currents influence, the ions adsorbed pass through anion and cation ion exchange membranes separately and are eliminated. The ion exchange process neednt use acid-alkali regeneration. This device can replace traditional ion exchange device, producing ultra-pure water with an electrical resistivity of 18MO.cm.
