This scientific research focuses on the study of the disinfection process of harmful microorganisms found in the Vyacheslav Reservoir using the ETRO – 02 ozonator installation based on pilot electrical corona discharge and ozone technology. The objective of the research is to determine the effectiveness of ozone technology in eliminating microorganisms in water and compare it with other disinfection methods. The materials and methods section reveals that ozone eliminates total coliform bacteria within 2 – 4 minutes at a rate of 99 – 100%, which is significantly faster than chloramine (which takes 15 – 30 minutes). Additionally, it was found that ozone decomposes into oxygen after use, leaving no harmful residues. The research results showed that ozone eliminates Clostridium spores by 85 – 90% within 10 – 15 minutes, while chloramine requires more time to reach the same efficiency. Ozone technology demonstrated an effectiveness of 95 – 99% at a pH range of 4.0 – 5.0, proving its suitability for different water conditions. Moreover, ozone works effectively under high temperatures and pressure. The findings indicated that at an ozone concentration of 1.0 mg/L, all harmful microorganisms in water are completely eliminated within 20 minutes. The research was conducted both theoretically and experimentally, with the mathematical model of water disinfection coded in Python. Mathematical calculations were performed using the SMath Solver software. In conclusion, ozone technology has been proven to be an effective, safe, and environmentally friendly method for water purification.

The primary objective of this study is to evaluate the effectiveness of ozone technology for water disinfection and to compare its efficiency with other disinfection methods.
