Agriculture needs new types of drugs to combat harmful microorganisms, the introduction of which will reduce the ingress of unnecessary chemical compounds into products. It is necessary to use anolytes more widely as alternative means of disinfection. The use of anolytes in various fields of industries has proven their high effectiveness and harmlessness. However, the production of anolyte is a complex electrochemical process, which results in a mixture of the necessary metastable elements. To obtain an anolyte with the required set of properties, it is necessary to study the physical and chemical processes of the activator in detail. The article proposes to use Comsol software for these studies. As a result of the modeling, the characteristics of changes in the concentrations of individual chemical elements over time and the main physical dependences of the activator itself were obtained. The analysis of changes in concentrations of chemical compounds confirmed the adequacy of mathematical models. There were installed points on electrodes with significant density of currents. Studies of changes in the hydrogen index and temperature allow you to set the required operating time of the activator. Analysis of concentrations of chlorine-containing compounds proves the difficulty of determining the rates of formation of individual chemical formations and their instability. On the basis of the obtained data, it is possible to recommend the mode of operation of the electrical activator depending on the properties of the source water and the requirements to the resulting solution.
