Electrodeposited Titanium Anode for Desalination



Electrodeposited Titanium Anode for Desalination
Electrodialysis desalination of seawater is achieved by electrodialysis desalination. In the case of a direct current electric field, when the raw water containing salts flows through the compartment composed of the anions, the cation exchange membrane and the separator, the anions and cations in the water begin to move, the anions migrate toward the anode, and the cations migrate toward the cathode. Since the ion exchange membrane has selective permeability, the immobilized exchange group of the cation exchange membrane (referred to as the cationic membrane) is negatively charged, thus allowing the cation in the water to pass through to block the anion. Anion exchange membrane (referred to as the negative membrane) of the fixed exchange group with a positive charge, thus allowing the anion in the water to block the cation, resulting in fresh water compartment in the ion migration to the concentrated water compartment, so as to achieve the purpose of desalination. Sea water and brackish water desalination, salt content can be up to 60g / L brackish water desalination into drinking water to solve the desert areas of drinking water problems. Electrolysis desalination device is widely used in food, light industry and other industries to obtain pure water; electronics, pharmaceuticals, chemical and other industries to produce high-purity water pretreatment; boiler water softening of the primary softening desalination; desalination of drinking water and some chemical products Desalination and so on. The electrode material is one of the key components of the electrodialysis desalter. This kind of electrode material requires both resistance to oxidation and resistance to reduction, that is to say both anode and cathode, but the general electrode material can not meet this requirement. For example, with graphite electrodes will be bad corrosion, shorter working life. At present, the ideal electrode is equipped with iridium-containing multi-component metal anode is the best, both to meet the requirements of the electrode backwards, but also has a low over-potential, with energy-saving performance, life than the general ruthenium Coated metal anode long. Our company can provide a variety of models of titanium anode, for the production of electrodialysis.
