The development of sea water conversion by electrochemical and electromembrane methods

There is developing the technological scheme of integrated conversion of sea water, which includes the receiving many components and products: concentrates of salt of metals, acids and alkalis, hypochlorites, hydrogen and oxygen, also bromine, and other products. The technologies consists of chemical, electromembrane, electrochemical and electroadsorptional stages, with maximal using of products in cycle of converting and keeping ecological rules. There were developed selective electrodes for electrolysis of sea water without formation of chlorine-containing products and also electrodialysis, electroadsorptional and electrolysis apparatus for corresponding processes. The integrated scheme of conversion of sea water differs from the schemes used before by the utilization products in cycle of conversion, by absence of addition reagents, relative simplicity of equipment, ecological, safety of technologies. This scheme was tested on model and natural sea water of Great Peter Bay of Japan Sea.
