The scientific research work is based on the process of destroying harmful microbacteria in surface water with the help of ozone technology, which are exposed to environmental problems. In general, this research paper carried out a comprehensive review of the literature published in scientific journals in the world in recent years on the process of neutralizing surface waters with traditional disinfectant reagents, which are subject to environmental problems. For example, we have highlighted the disadvantages and advantages of oxidizing agents and disinfectant reagents such as chlorine (Cl), chloramin (NH2Cl), chlorine dioxide (ClO2), ozone (O3) and ultraviolet (UV). However, among these reagents, considering the advantages of ozone technology, according to the research work, there is a special Current to ozone technology. The scientific novelty of the research work was the creation of a modern ozonator unit Etro – 02 based on an electric corona discharge with a frequency of 13 kHz, a voltage of 21 kV. For testing the installation, surface water was taken from the Kapshagai and Vyacheslav reservoirs, where aranai was exposed to environmental problems, and expert samples were carried out. The number of microbiological indicators that do not meet the standards found in the composition of water is as follows: total number of microbes 130-160 (1 ml of CFU (Colony-forming unit)), TCB (Thermotolerant coliform bacteria) 270-370 (100 ml of CFU), CCB (Common Coliform Bacteria) 650-800 (100 ml of CFU), coliphages 135-170 (100 ml of PFU (plaque – forming units)). To completely neutralize and clean these bacteria, the amount of ozone consumed per 1m3 of water was enough for 0.5 – 0.8 g/hour of ozone. And it turned out that the decontamination time will be enough 20 – 25 minutes. In addition, the obtained data were used to compile a mathematical model using the programs “Mathcad 14” and “SMath Solver”.
