EDI device is used to produce stable deionized water after the RO system. The produced water enters the EDI module and is distributed to the fresh water chamber. The trace ions are adsorbed on the membrane surface by the ion exchange resin. Under the action of current, the cation and anion in the fresh water chamber are driven to migrate to the corresponding electrode to the concentrated water chamber, so as to produce high-purity water. No acid-base chemical regeneration, continuously production no environmental problems. It is the most advanced and reliable technology in the process of preparing high purity water.
EDI technology is applicable to the preparation of ultrapure water in electronics, chemical industry, medicine, electric power, aerospace and other industries, as well as the preparation of make-up water for medium and high pressure boilers.
