1.0m3/h RO EDI Softened Water Plant for Deionized Water
RO EDI WATER PLANT DESCRIPTION
RO+EDI ultra pure water treatment equipment uses pre-treatment, reverse osmosis technology, ultra purification treatment, and post treatment methods to almost completely remove the conductive medium in the water, while also removing non dissociative colloidal substances, gases, and organic substances in the water to a very low degree.
EDI (Electrodeionization) is a pure water manufacturing technology that combines ion exchange technology, ion exchange membrane technology, and ion electromigration technology. It cleverly combines electrodialysis and ion exchange technology, utilizing high voltage at both ends of the electrodes to move charged ions in water, and cooperates with ion exchange resins and selective resin membranes to accelerate ion removal, thus achieving the goal of water purification.
In the EDI desalination process, ions are removed through ion exchange membranes under the action of an electric field. At the same time, water molecules generate hydrogen ions and hydroxide ions under the action of an electric field, which continuously regenerate the ion exchange resin to maintain its optimal state.
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.
