Analysis of the health status of bee colonies has shown that constant prevention and treatment of bees from concomitant diseases is necessary. The health of bees is directly related to their productivity. Most beekeepers use highly active chemicals to process beehives and inventory. To change this situation, it is necessary to search for new solutions for the treatment of bees. One of the ways to solve the problem is the use of environmentally friendly and harmless to bees and beekeepers electroactivated solutions obtained using diaphragm electrolyzers of water. The conducted studies of the developed model of a diaphragm electrolyzer using the Comsol program allowed us to obtain information about the physicochemical processes occurring in it over time. Comparison of simulation results and experimental data showed their good coincidence. Studies on the treatment of bee colonies in the apiary with electroactivated solutions can halve the use of chemicals and reduce the likelihood of drugs getting into bee products.
