METHOD OF ACTIVE CONTROL OF PARAMETERS OF THE ELECTROCHEMICAL PROCESS OF A LIQUID TREATMENT Russian patent published in 2005 - IPC

FIELD: chemical industry; methods of active control of parameters of a liquid treatment electrochemical process.

SUBSTANCE: the invention is pertaining to the field of chemical industry, in particular, to an electrolytic treatment of a liquid, for example water, with ions of a metal, mainly silver. The offered method of active control is based on the choice of the original timing and the current of a liquid treatment in compliance with Faraday's laws. After beginning of the treatment process conduct a measurement of the speed of the change of voltage on the electrodes which acts as a complex index mirroring the change of electrical conductance of the liquid between the electrodes at its treatment with ions of a metal. The indicated index depends on parameters of the treated water and is proportional to productivity of the electrolyzer by a mass of the dissolved metal per a unit of time. Depending on the value and the sign of the voltage change speed conduct a correction of the current of the electrolyzer and-or the time of treatment and seek a stability of the produced concentration of ions of silver in the water. The technical result is simplification of the process of the active control at the expense of exclusion of multiple sensors as well as operations of the regular gauging and maintenance of the ions selective sensor under condition of maintenance of stability of the achieved level of concentration of a metal ions in the liquid.

EFFECT: the invention ensures simplification of the process of the active control, stability of the achieved level of concentration of a metal ions in the liquid.
