Introduction. Escherichia coli, Staphylococcus aureus and Salmonella spp. pose the greatest threat to human health due to their growing resistance to antibiotics. In Makhachkala, the largest water bodies are the October Revolution Canal (ORC), which is used for the central water supply of the city, and water treatment facilities - systems designed to purify wastewater.
Purpose of the study. Comparative assessment of the effect of hydrogen peroxide and hypochlorite on microorganisms of sanitary and epidemiological significance, as well as determining the effectiveness of ultraviolet (UV) disinfection in relation to bacterial contamination of drinking water.
Materials and methods. Three samples of drinking water were used: bottled drinking water, tap water (Makhachkala) and natural water from the ORC before delivery to consumers. Then the water samples were processed. Pure cultures of E. coli, Staph. aureus and Salmonella spp. bacteria were used for control in the work.
Results. When processing water samples using a modified method, a pronounced bactericidal effect was found, which is expressed in a decrease in CFU. The maximum antimicrobial effect was observed with a combination of UV with peroxide and UV with hypochlorite.
Limitations of the study. In tap water and natural water from KOR, pathogens of serious diseases were identified. Therefore, it is necessary to expand knowledge about water sources as reservoirs and distributors of these pathogens.
Conclusion. The proposed highly effective water treatment methods can be of practical importance for providing city residents with water purified from microorganisms.
Keywords:water purification, oxidizing agents, pathogenic microorganisms.
