Abstract: The invention relates to the treatment of water by electrochemical activation and can be used for the preparation of high quality potable water in everyday life, as well as in industry.The proposed invention is based on the task for creation of such a method for electrochemical activation of potable water that with the help of choice of optimal number of electrochemical reactors, choice of the most effective parameters of electrical and magnetic fields, will allow influencing on water in such a way, that at its treatment in flow regime to achieve maximum efficiency at treatment of water from metal salts, especially at their increased salt content, effectively decontaminate water, provide necessary productivity treatment and consume minimal quantity of electrical energy. According to the invention the method for electrochemical activation of potable water comprises passage of water through a filter for the preliminary treatment, and then influence on water with electrical field, applied to electrochemical cell of double-diaphragm electrolyzer with anode and cathode chambers. After preliminary treatment water is divided to three fractions, acid medium is formed in the first fraction, in the second – neutral, and in the third – alkaline, then each fraction is successively passed through anode, neutral and cathode chambers of double-diaphragm three-chamber electrochemical reactors, the number of which is chosen under condition of, where- a total number of electrochemical reactors;- a number of groups of electrochemical reactors;- a number of electrochemical reactors in the group, in which anode and cathode chambers are filled with granulated loading; and- a number of electrochemical reactors in the group, in which anode and cathode chambers do not contain granulated loading, and at transition of water streams from one group of electrochemical reactors to another the change in streams of acid medium is carried out to alkaline and vice versa, and all fractions simultaneously in all electrochemical reactors are influenced with pulsating electrical and pulsating magnetic fields, and then acid and alkaline fractions are filtered and mixed, obtaining potable water, and in the end of treatment cycle of water according to the method four types of water are obtained: filtered acid fraction - "anolyte" and alkaline fraction - "catholyte", and also "neutral" fraction and "potable" water.
