Electrodeionization - EDI Modules for Water Polishing

Electro De-Ionization is currently the most advanced technology for ion-exchange. With this technology (ultra)pure water can be produced continuously. This high-end technology can have an application in sectors such as: Power plants, process industry and pharmaceutical industry. An EDI-unit is usually used as a post treatment of Reverse Osmosis water.



  • Description
  • Electrodeionization (EDI) is an electrically-driven water treatment technology that uses electricity, ion exchange membranes and resin to remove ionized species from water.<br
    It is wisely combined electro dialysis with ion exchange technology,by using of high-voltage electrodes at both ends to drive charged ion in the water to move,and with the ion exchange resin and selective resin membrane to accelerate ions moving,so as to achieve the purpose of water purification.
