EDI system(Electrodeionization) is also called continuous electric desalination technology, which scientifically integrates electrodialysis technology and ion exchange technology, through the selective permeation of cation and anion membranes on cation and anion membranes, and the exchange of ions in water by ion exchange resin Function, realize the directional migration of ions in the water under the action of the electric field, so as to achieve the deep purification and desalination of water, and continuously regenerate the filling resin through the hydrogen ions and hydroxide ions produced by water electrolysis, so the EDI water production process does not need The regeneration of acid and alkali chemicals can continuously produce high-quality ultra-pure water. It has the advantages of advanced technology, compact structure, and easy operation. It can be widely used in the fields of electricity, electronics, medicine, chemicals, food, and laboratories. A green revolution in processing technology. The effluent quality has the best stability.
Electro-deionization (EDl system) is a scientific water treatment technology, in which dielectric ions in water passing through the partition move directionally under the action of a DC electric field, and water quality is purified by selective permeation of ions by exchange membrane. Between a pair of electrodes of electrodialysis, a plurality of groups of negative membranes, positive membranes, and separators (A and B) are alternately arranged to form a concentrated chamber and a weak chamber (i.e., cations can pass through the positive membrane and anions can pass through the negative membrane). Cations in the light chamber water migrate to the negative electrode and pass through the positive membrane, and are intercepted by the negative membrane in the concentrated chamber; Anions in the water migrate to the cathode direction and are intercepted by the anode membrane in the concentrated chamber, so that the number of ions in the water passing through the light chamber gradually decreases and becomes fresh water, while the concentration of dielectrics in the concentrated chamber continuously rises due to the continuous influx of anions and cations in the concentrated chamber, and becomes concentrated water, thus achieving the purpose of desalination, purification, concentration or refining.

Applications of EDI System

Electronics, electroplating, power plants, medicine, petroleum, chemical, food and beverage, printing, and dyeing industries.
