Abstract: There is proposed a water treatment method by causing the water to be pured to flow through a first and a second compartments arranged in succession in an electrolysis cell divided by a permeable membrane into said first and second compartments. Each of the compartments accomodates an electrode, one of them being an anode, and the other--a cathode. Direct electric current is then passed through the water between the anode and the cathode, the current value being determined from the following equation:I=K.times.(C).sup.1/4 .times.Q,whereinI is the current amperage (A),C is the feed water mineralization equal to 0.1-1.5 g/l,Q is the water flow rate (1/hour), ##EQU1## the I/Q ratio being comprised within from about 110 to about 220 Coulomb/liter. The water is caused to flow successively from the anode compartment towards the cathode compartment. Once the water is discharged from the cathode compartment, it is subjected to filtering by passing the water through a bed of a porous carbonaceous material.

Abstract: An apparatus for electrical treatment of water can be used for purifying and disinfecting potable water, and also for producing detergent and disinfecting solutions, and comprises at least one electrochemical cell made up of an upright cylindrical electrode and a rod electrode of a variable cross-section mounted coaxially in dielectric sleeves, an ultrafiltration diaphragm made from ceramics based on zirconium oxide and coaxially mounted in the sleeves between the electrodes, the geometrical dimensions of the cell meet some definite relationships. The system of openings in the electrodes and ducts in the sleeves provides for the optimal hydraulic characteristics of the cell. The sleeves and cylindrical electrode have the same external diameter and the cells are specially secured by means of gaskets in the upper and lower headers of a dielectric material with cylindrical sockets in each and supply and discharge ducts.
