Frotec EDI (Electrodeionization) Module


EDI(ELECTRODEIONIZATION) base one merging ED and ion exchanger , an economical way to produce high purity water continuously -no batch regeneration, no hazardous chemicals. With the advanced technology ,easy operation, and environmental advantage, it is represent the directtion of this field.EDI equipment includes booster pump , edi module ,dc regulated power supply,flow meter and instrument, purify water is forced into EDI system by boost pumps, mixed ion exchange resin will continuously remove the impurities from the water by ion exchange.Meanwhile , the electroly to stream flows past the anode and cathode in series, the applied current also drives a water splitting reaction which produces hydronnium ions and hydroxylions. These ions continuously regenerate the ion exchange resin so that it will continue to remove impurities from the feed water. Then re-displaced cation and anion from the feed water water will permeate into concentrate chamber by some times reverse osmosis. As a result, a portion of concentrated is recycled back to keep the conductivity.
