The use of silver water in apiaries in order to increase the viability of bee colonies can significantly increase their profitability. The concentration of silver ions in water should be: for drinking bees – 0,5–1,2 μg/l, for making syrup –3,5–10 μg/l, for washing hives and disinfection – 18–60 μg/l and for the treatment of bees – 60–80 mcg/l. The second feature of such devices is their work in the field, which requires high reliability of the device, good performance, ease of use and protection against moisture and mechanical stress from the external environment, as well as ease of carrying and transportation. The article describes the device for producing silver water “Erviy 3”, developed by employees of the Volga State Technological University for use in apiaries. The main disadvantage of all existing devices for producing silver water is that silver water is formed in a given volume and can be obtained periodically in limited quantities, and then diluted with water to the desired concentration. This leads to difficulties in obtaining and using silver water in large agricultural and industrial enterprises and in medical institutions. The main goal of this work is to create a facility for the continuous production of silver water with high accuracy of a given concentration of silver ions for large agricultural, medical and industrial institutions. In the proposed installation, in order to reduce errors in the concentration of water by silver ions, a new methodology of the ionization process by the amount of electricity during the ionization of water is used. The article presents a block diagram of the installation for the continuous production of silver water with high accuracy by a given concentration of silver ions and its operation is described. The installation is characterized by ease of operation, high technical parameters, low cost and can be recommended for use in apiaries in various regions of the country.
