Abstract: according to the World Health Organization, 80% of diseases are caused by poor quality of drinking water. Therefore, human life, animals, plant growth and development depend on the quality of water. Currently, when there is a continuous increase in the cost of medicines, fertilizers, pesticides, the problem of replacing the above drugs with cheaper substances is relevant. To solve this problem, it is proposed to use electro-activated water and aqueous solutions. On the basis of domestic and foreign experience, leading experts have developed methodological instructions for the widespread use and use of electro-activated water and aqueous solutions in engineering, agriculture, and medicine. For the production of electrochemically activated water and solutions, non-flowing and flow-through modular elements, as well as universal installations, were developed. Currently, a wide variety of electroactivators is offered. Analysis of the structures of these devices showed that flat metal plates are used as electrodes, therefore there are volumes of water that are exposed to uneven electrochemical effects. As a result, the specific energy consumption for obtaining activated water is significant. The purpose of the work is to reduce the specific energy consumption in the production of activated water and aqueous solutions. Coaxial arrangement of the electrodes leads to a reduction in energy consumption. Studies of the electroactivator of water with a coaxial arrangement of electrodes made it possible to establish the optimal ratio between the volumes of anolyte and catholyte and the time of electrolysis of water and an aqueous solution of sodium chloride. The results of the research can be used in the production of electroactivators for personal use as well as in industry and agriculture.
