Information confirming the possibility of implementing the claimed invention are as follows.

Installation for electrochemical activation of water used for drinking purposes in industry, medicine, microelectronics, laser technology and crop irrigation in drip irrigation systems with redox properties to ensure increased biological activity and optimal growing conditions of crops in order to obtain maximum yield consists from a housing 1 made of dielectric material, in the lid of which a water supply pipe is mounted water supply 2, providing water supply to the cathode 3 and anode 4 chambers. Two perforated cathodes 5 and anodes 6 are installed in each chamber 3 (4). The cathode 3 and anode 4 chambers are separated by microporous plastic gaskets (separators) 7. In the lower part of the housing 1 there are made pipes 8 for draining water with a negative potential (catholyte) and pipes 9 for draining water with a positive potential (anolyte).

Pipelines 10, 11 are designed to discharge catholyte and anolyte through control valves 12, 13 to the corresponding consumers of activated water.

The positive potential electrodes 6 are connected to the positive potential bus 14, and the electrodes 5 are connected to the negative potential bus 15. In the anode chambers 4, inserts 16 of profiled sheet metal are installed, and in the cathode chambers 3, inserts 17 of profiled sheet metal are installed.

The inserts 16 and 17 are connected to the anodes 6 and cathodes 5 and carry the corresponding potential of the chamber in which they are installed.

Multi-threaded installation for electrochemical activation of water works as follows.

In the water supply or drip irrigation system, after cleaning from impurities, the flow under the working pressure, which should be twice as much as the required pressure in the outlet pipelines 10, 11, is sent through the water supply pipe 2 to the installation casing. The treated water enters the cathode 3 and anode 4 chambers. Simultaneously with the supply of water to the electrodes, a potential of 12 ... 24 V.

At the same time, the water flow passing through the channels between the inserts 16, 17 of profiled sheet metal acquires the properties of turbulent motion, which increases the possibility of contact of all particles of the flow with negatively and positively charged electrodes 5, 6, which accordingly increases the efficiency of electrochemical water treatment and reduced consumption energy for processing from exposure to a negative potential, in the cathode chamber 3 get catholyte with a pH of 10.0 ... 12.0 and ORP in the range of 850 ... 1100 mV, and in the anode chamber - anolyte with a pH of 3.0 ... 5.0 and oxides recovery potential (ORP) equal to +560 ... + 1100 mV. At the same time, the specific cost of the amount of electricity is not more than 400 coulomb per liter (C / l). Treated water in the form of anolyte and catholyte enters through valves 12, 13 to consumers. In this case, the water flow can be regulated, which causes a change in pH and ORP.

The tests showed that the treatment of seeds of agricultural crops with anolyte ensures the destruction of most pathogenic microbes and pests, and the treatment of seeds with catholyte increases their germination and germination energy.

The drip irrigation of crops of watermelons of the Kholodok variety made it possible to obtain products 12 days earlier, and the yield increased by 30%.
