Abstract: Introduction. Numerous studies have shown that treating and watering plants with activated water have a beneficial effect on their growth and productivity that is why procedures and methods for preparing such water are very relevant. This work examines the method of preparing catholyte and anolyte in the so-called flow-type electroactivator, which is installed in an automated system for watering plants in greenhouses and open ground. Water for watering plants should have the pH index recommended for these conditions, so it is necessary to establish an adequate relationship between the operating mode and operating parameters of the electroactivator, on the one hand, and the pH index of water, on the other. At present, the issue of developing an adequate mathematical model for water activation in a flow-type electroactivator requires studying. The article proposes a mathematical model in which there is established relationship between the pH index of water, activation mode and flow-type electroactivator parameters.Aim of the Study. The article is aimed at increasing the efficiency of an automated system for watering with activation of water in a flow-type electroactivator.Materials and Methods. The calculation of the water activation parameters in the electroactivator was carried out using a mathematical model of the water electroactivation in a flow-type electroactivator based on physical and electrical chemistry methods using differential equations and calculations in the Lazarus programming environment. The experiments to assess the adequacy of the model were carried out on a developed experimental facility.Results. There have been developed a mathematical model of water activation and experimental facility to test the adequacy of the mathematical model. There are substantiated the formulas determining relationship between the pH index of activated water, parameters of a flow-type electroactivator and electroactivator operating mode parameters necessary for developing an automated plant watering system. It has been found that the mathematical model of water activation in an electric activator allows estimating the pH index with an error of less than 5% when the potential difference between the electrodes is not higher than 125 V. In this case, the work of the current to heat and produce a unit of catholyte substance for a specified increase in the pH index is less, the lower the productivity cathode chamber is. Theoretical studies have shown that for a specified change in the pH index, the current power spent on heating the catholyte increases in direct proportion to the square of productivity of the cathode chamber, and the energy intensity of producing a catholyte unit increases in direct proportion to the productivity of the cathode chamber. It has been confirmed experimentally that the pH index changes in parallel with changes in the temperature of the anolyte and catholyte, directly proportional to the potential difference between the electrodes, and inversely proportional to the performance of the chambers. In this case, it is advisable to set the productivity of the cathode chamber with the specified parameters no higher than 15 l/h, and the temperature of watering with catholyte no higher than 25°C.Discussion and Conclusion. The developed mathematical model of water preparation in a flow-type electroactivator can serve as the basis for an automated plant watering system, in which it is necessary to ensure a suitable operating mode depending on the specified the pH index of water.
