EDI high purity water plant

Product Description

Electrodesalination, also known as Electrodeionisation (EDI), is a scientific integration of electrodialysis and ion exchange technology, and is a desalination plant consisting of cation and anion exchange membranes, concentrated and fresh water separators, cation and anion exchange resins, positive and negative electrode plates and end pressure plates etc. EDI is an emerging membrane separation technology, the core of the technology is to use ion exchange Resin as the carrier of ion migration, cation and anion exchange membrane as the separation interface, under the action of DC electric field to make the water ion directional migration, so as to achieve the process of salt water separation. At the same time, the hydrogen ions and hydroxide ions generated by water electrolysis are continuously regenerated by the loaded resin, so the EDI water production process can continuously produce high quality ultrapure water without regeneration of acid and alkali chemicals, which has the advantages of advanced technology, compact structure and easy operation, and can be widely used in electric power, electronics, medicine, chemical industry, food and laboratory fields.
