2D Desalination

Electro dialysis (ED) technology is an electro-membrane process in which an anion exchange membrane and a cation exchange membrane are arranged between two electrodes in a direct current field. Under the influence of an electrical potential difference, cations moving toward the cathode are transmitted through the cation exchange membrane and are held by the anion exchange membrane, while anions moving toward the anode are transmitted through the anion exchange membrane and are held by the cation exchange membrane. Accordingly, ions in the water are separated. Electro dialysis technology is used for seawater desalination, sewage purification, heavy metal wastewater treatment, and acid purification.
