The invention relates to water purification methods that reduce the content in the purified water (c) salts, hardness, eliminate the consumption of reagents, ensure the continuity of the cleaning process B. The method of non-reagent intelligence B includes its electrochemical treatment, clarification, filtering. Electrochemical treatment B before clarification is carried out by electrolysis using soluble anodes of iron until the water content of iron hydroxide is 15-30 mg / l in terms of iron, clarification is carried out at pH 11.0-11.5 and after filtering, water is supplied to acidic and Alkaline chambers of an electrodialyzer with alternating cation-exchange and bipolar membranes, and the obtained alkali is fed for clarification. s 2 np. 1 tab.
