Electroseepage is a physicochemical process that uses the selective permeability of the ion exchange membrane under the action of the external DC electric field. The Electro seepage desalination device is to use the electro seepage process in multi-layer compartments to achieve the purpose of water desalination. The application of electro seepage in wastewater treatment engineering is mainly wastewater desalination and the recycling and utilization of useful substances. In some biochemical wastewater, COD, as well as the salt content, are very high. When treating these wastewaters with the biochemical method, bacteria can not grow due to the high concentration of salt, which can be desalted with electro leachate to reduce the salt content before biochemical treatment. In paper wastewater, electroplating wastewater, and other recyclable inorganic salts, can be used by electro seepage for recycling.
Electro Seepage Seawater Desalination
Electrolysis of seawater chlorine production is a safe and effective pollution prevention measure, which has been widely used in the biological pollution prevention system of coastal thermal power plants, nuclear power plants, ships, etc. Natural seawater contains a large number of salt substances, and the main component is sodium chloride (NaCl). Generally, the chloride content in seawater is about 15 ~ and 19 g/L.Electrolytic seawater antifouling is used in a diaphragm-free electrolysis tank to produce effective chlorine (including HCIO, CIO-, Cl2), strong oxidants that can kill anhydrobiotic larvae or spores for the purpose of preventing its attachment and growth. Large electrolytic seawater pollution prevention system in coastal power plants and coastal plants is mainly composed of seawater electrolytic tank group, power distribution equipment, and seawater delivery. Part of the seawater electrolyte tank group is the most critical technology.
The main factor restricting the development of electrolytic tank technology is the anode materials. It must have a lower chlorine precipitation potential and a higher oxygen precipitation potential and must have a long service life and a higher electrolytic efficiency. The anode materials in the seawater electrolytic chlorine pollution prevention device have an important impact on its performance, and also directly affect the operating cost of customers.
