Product Details
Continuous electrodeionization device: It integrates electrodialysis technology and ion exchange technology scientifically, realizing the directional migration of ions in water under the action of electric field through the selective permeation of cations and anions by anodic and anionic membranes and the exchange of ions in water by ion exchange resin, so as to achieve the deep purification and desalting.
