In the agricultural production and processing industry, technological processes in which electroactivated water and solutions based on it are effectively used are very widespread. The development of installations for the electroactivation of water and the optimization of operating modes are undoubtedly topical issues, the solution of which will make it possible to use them more effectively in agricultural practice. The results have been presented of studying the operational characteristics of a nonflowing device for the electroactivation of tap water both with an unchanged area of the separation membrane between the anode and cathode compartments and when this area changes its dimensions. Studies have made it possible to establish that, at a constant value of the working area of the separation membrane, the minimum consumption of electricity corresponds to the smallest interelectrode distance. Approaches for implementing effective operation of the electrotechnological installation are proposed.
