Developments in Ukraine and the world on the project 
Among the numerous methods of processing, conditioning and disinfection of water occupy a significant share of electrochemical methods. This is primarily electrocoagulation, electroflotation, electrolysis, electrochemical oxidation, electrolytic extraction of metals from wastewater and sludge, electropulse water treatment, electrodialysis (Duhin SS, Bolt Lopis VR, Zhovkva EK Electrosurface phenomenon and elektrofiltrovanie - Kiev: Naukova Dumka, 1985. - 286.

The electrocatalytic reduction of nitrate in water on Pd / Sn-modified activated carbon fiber electrode. Ying Wang, Jiuhui Qu, Rongcheng Wu el. Water Res .- 2006.-V.40, N6 - P .1224-1232 ) It is known that by using these methods of water treatment on the cathode reaction hydrogen and form deposits, and at the anode, the formation of oxide films and oxygen. In addition to the classical electrochemical methods of water treatment of its expansion can be achieved by photocatalytic processes that use high-performance catalysts developed surface and sunlight.

But so far the development of methods for water treatment has been aimed only at getting the final product of pure water. Therefore, the intensification of the use of innovative approaches to creating multi-functional system generation, accumulation of hydrogen - water air conditioning with the requirements of consumers in domestic, international practice and the literature are too often absent.
