摘要： The invention relates to the field of water purification. A method for sening water by way of its electrochemical treatment involves causing water to pass in the form of two streams through anode and cathode chambers of a membrane electrolyzer. According to the invention, the water stream being fed to the anode chamber is preliminarily softened before supplying it to the anode chamber, and this stream is in the form of catholyte after the separation of precipitating hardness salts therefrom, anolyte being used as the end product. An electrolyzer for softening water has a casing divided by membranes into anode and cathode chambers, respectively. According to the invention, anodes are spaced from the membrane, and perforation holes of a cathode are in the form of slits extending about perpendicularly with respect to the water flow direction, and projections are provided on the surface of the cathode facing towards the interior of the cathode chamber inbetween the slits, the leading faces of the projections in the flow direction being inclined at an agle of 20.degree. to 40.degree. with respect to the surface of the membranes.The invention may be used in any fields where water softening is required.
