METHOD OF ELECTROCHEMICAL TREATMENT OF THE WATER-SALT SOLUTIONS Russian patent published in 2006 - IPC C02F1/46 

FIELD: treatment of water-salt solutions; methods of electrochemical treatment of water-salt solutions.

SUBSTANCE: the invention is pertaining to the method of the electrochemical treatment of water-salt solutions of the alkaline metals sodium chlorides for the purpose of production of the disinfectants and detergents, and also for regulation of the acid-base parameters of water. The total stream of the initial solution at the inlets into the cathode and anodic chambers is uniformly divided into the system of parallel streams. The streams are passing over the surfaces of the electrodes in the laminar flow mode through hydrodinamically separated channels formed by the surfaces of the diaphragm and the equidistant surfaces of the electrodes having a configuration of a plane wave. The treatment of the solution is conducted at the given density of the electrical current and the selected speed of the flow maintaining the ratio of the mode parameters and the geometrical parameters of the channels within the limits defined by the criterion of the hydrodynamic stability of the laminar flow of the solution to the disturbances from the concentration-gravitation convection and the condition of the bubble mode of evacuation of the electrolysis of gases in the channels. The technical result of the invention is an increased hydrodynamic stability of the processes of the electrochemical treatment of the laminar flows of the lightly compensated water-salt solutions in the large planar-slot electrode channels of the electrochemical components, an increase of intensity and power efficiency of the processes of the electrochemical treatment of solutions and increased productivity of the running electrochemical components.

EFFECT: the invention ensures an increased hydrodynamic stability of the processes of the electrochemical treatment of the lightly compensated water-salt solutions in the large planar-slot electrode channels of the electrochemical components; an increased intensity and power efficiency of the processes of the electrochemical treatment of solutions; an increased productivity of the running electrochemical components.
