It is divided into two kinds of electrodialysis cathode membrane and electrodialysis anode membrane. The cathode membrane has the characteristics of blocking cations through anions, and the anode membrane has the characteristics of blocking anions through cations. The cathode membrane and the anode membrane are alternately arranged, and the salt can be transferred under the action of DC electric field, so as to realize the removal or concentration of salt.
Note: The above data are all reference values, but the performance guarantee values of non-ionic membranes. The data in the table may be changed.
(1) Chemical/food/pharmaceutical and other types of production process liquid salt removal;
(2) industrial primary water desalination, industrial water desalination, industrial salt wastewater treatment, reverse osmosis concentrated water desalination and other industrial water preparation, treatment and recycling;
(3) surface water purification, brackish water desalination and desalination of life and drinking water preparation.
