Removal of selected bacterial strains from raw water by disinfection with sodium hypochlorite

Water disinfection is an essential phase in the water supply process conducted to ensure safe drinking water, serving as the last barrier against the transmission of bacterial and viral infections through water. The main factors affecting disinfection efficiency, and consequently the type of water treatment process, include the type and concentration of organisms to be removed, the type and concentration of the disinfectant, contact time, and the chemical nature and temperature of the treated water. Therefore, this paper presents the results of the removal of selected strains to examine the effective dose and contact time of sodium hypochlorite. The results show that the application of this disinfectant can effectively remove the selected strains. A significant reduction in bacterial count was achieved, ranging from 2 to 4 log units depending on the sensitivity of the strain, at a C∙t value of 120 min∙mg/l, i.e., a dose of 2 mg/l and a contact time of 60 minutes.
