Background technology
EDI electrodeionizations（Electro-deionization abbreviations EDI）Technology is a kind of new pure water and ultra-pure water
Technology of preparing.The technology blends electrodialysis and ion exchange technique, by anions and canons exchange membrane to anions and canons
Selection is acted on ion exchange resin to the exchange interaction of ion by property, and the orientation of ion is realized in the presence of DC electric field
Migration, so as to complete the deep desalting of water, produces resistivity up to 18.2M.cm ultra-pure water.
In EDI device, by being removed after resin, water is purified the various ions in water inlet, be now utilize from
Sub- exchange principle removes the ion in water.Because amberplex both sides are added with voltage, hydrone is electrolyzed to produceWithGo
Regenerating resin, while quiltWithIon under ion exchange is migrated to concentrated water room row in the presence of current regulator power supply
Put, so as to realize cyclic regeneration, the continuous purpose for using.
EDI device is in continuous working condition after opening, and is constantly intake and output pure water in the course of work, once for
Water is interrupted, and EDI membrane stacks just occur the serious consequence of dry combustion method, cause EDI device to scrap, and is directly other works due to EDI device
Sequence scene provides pure water, and EDI device damage can interrupt whole production process, and consequence is quite serious, and EDI device is in itself
