The electrochemical treatment of water by the electric current is a promising modern approach in the water disinfection technique, resulting in obtaining the electrochemically activated water solutions (catholyte/anolyte) carrying new physical-chemical properties stipulated by changing of the electrochemical characteristics of water as ORP, Eh, pH. The electrochemically activated water solutions – the catholyte and anolyte can be used in medicine for treatment of various bacterial and viral diseases and in disinfection of water. The process of electrochemical water treatment includes several electrochemical processes associated with the transfer in a constant electric field the electrons, ions and other charged particles (electrolysis, electrophoresis, electroflotation, electrocoagulation), the main of which is the electrolysis of water. This article deals with the review of basic physical-chemical processes underlying the electrolysis of water and preparation of electrochemically activated water solutions (catholyte/anolyte) and studying their physical-chemical properties. The virucidal action of the anolyte and catolyte was studied on cell culture and suspensions of classical swine fever (CSF) virus. Key words: electrochemical treatment of water, anolyte, catholyte, electrolysis, classical swine fever (CSF) virus
