What is EDI ultra pure water system?

Electro-deionization (EDI) is an electrically-driven water treatment technology that uses electricity, ion exchange and resin to remove ionized species from water. The combination of ion-exchange resins and ion-exchange membranes, which are used to move ionic impurities into a waste or concentrate water stream leaving purified product water.

How does EDI module work?

EDI Modules are usually used after two pass ro systems,two pass ro systems will remove 99% impurities from the water , Water enters the EDI module, where an applied current forces ions to move through the resins and across the membranes. These ions are collected into concentrate streams which can then be put to drain or be recycled. The deionized product water can then be used directly or undergo further treatment for enhanced water purity.

PLANT DESCRIPTION

RO+EDI watertreatment equipment, the use of pretreatment, reverse osmosis technology, ultra-purification treatment and post-stage treatment methods, the conductive medium in the water is almost completely removed, and the water does not dissociate the colloid substances, gases and organic matter are removed to a very low degree of water treatment equipment.

EDI (Elcctrodeionization) is a pure water manufacturing technique that combines ion exchange technique, ion exchange membrane technique and ion electromigration technique. It cleverly combines electrodialysis and ion exchange technology, using high voltage electrodes at both ends to make charged ions move in water, and with ion exchange resin and selective resin film to accelerate ion movement removal, so as to achieve the purpose of water purification. During EDI desalting, ions are removed through ion-exchange membranes under the action of electric field. At the same time, water molecules generate hydrogen ions and hydroxide ions under the electric field, and these ions continuously regenerate the ion exchange resin to keep the ion exchange resin in the best condition. The equipment has the advantages of compact structure, small area, high unit water production, less energy consumption, thorough removal of impurities, wide range of use, high degree of automation, easy to use and operation, no pollution and so on.
