EDI Pure Water Equipment
EDI Pure Water Equipment
Electrodeionization technology is a novel method for preparing pure water, combining ion exchange technology, ion membrane separation technology, and ion electromigration technology. An EDI module comprises multiple units linked in parallel. Each EDI unit includes an ion exchange resin, membrane, and a DC electric field. Ion exchange membranes are categorized into anion exchange membranes and cation exchange membranes. Cation exchange membranes allow only cations to pass through, blocking anions and water.
Conversely, anion exchange membranes permit only anions to pass. The anion and cation exchange membranes are arranged alternately to form a series of concentrated and freshwater chambers. The freshwater section is filled with an anion-cation mixed ion exchange resin. Under the influence of the applied DC electric field, cations move towards the cathode, while anions move towards the anode. They each enter the adjacent concentrated water chamber via the ion exchange membrane, consequently reducing the ion content in the water of the freshwater channel and achieving water purification.
