Continuous Electro-Deionization (EDI, Electro-deionization) is a method that uses mixed ion-exchange resins to adsorb anions and cations in water. At the same time, these adsorbed ions are passed through anion-cation exchange membranes and concentrated under the action of DC voltage. The electrode is removed from the water chamber. On the other hand, under the effect of DC voltage, water will dissociate to produce enough H + ions and OH- ions to achieve continuous deep desalination. This new technology can replace traditional ion exchange (DI) to produce pure water with a resistivity of up to 18MΩ. The most significant advantage of EDI is that it eliminates the need to regenerate ion exchange resins with acids and bases and is therefore more environmentally friendly.
Inflow of water and concentrated / polar water countercurrent (countercurrent) to avoid scaling
Special ion exchange membrane with high exchange capacity and strong selectivity
No salt required during operation, reducing operating costs
All water chambers are fully filled with resin to improve ion migration efficiency and reduce energy
