(Electro-deionization, or EDI) The process of electro-deionization involves the use of mixed ions of anionic and cation from water adsorption and ion exchange resin. At the same time, ions are adsorbing through an ion exchange membrane into a thick anionic and cation water chamber and being removed; at the same time, water can produce enough dissociation of H + ions and OH- ions under the action of DC voltage to achieve continuous deep desalting. This innovative method can provide a resistance rate of up to 18 MΩ in pure water, which can replace the conventional ion exchange (DI). The main benefit of EDI is that it is more environmentally friendly because it does not require the regeneration of ion exchange resins with acids and bases.
