The electrodialyzer utilizes ion exchange membrane and DC electric field to selectively migrate ions of electrolyte in water, so as to achieve water desalination device, referred to as ED. Electrodialyzer consists of anode chamber, intermediate chamber and cathode chamber. Electrodialysis is essentially a desalination technology. The positive and negative ion exchange membranes in the electrodialysis device have selective permeability, and a salt-containing solution is placed in the device. Under the action of direct current, the positive and negative ions permeate the membrane and migrate to the cathode and anode respectively. Finally, in the intermediate chamber between the two membranes, the concentration of salt decreases, and the cathode and anode chambers are concentrated chambers. Electrodialysis methods can desalinate, concentrate, separate or prepare certain electrolytic products of electrolyte solutes or certain substances.
There are many pieces of spacers in the electrodialyzer, we update the design of the spacer in an electrodialysis process all the time.
