Chemical and disinfectant properties of a chlorine-containing chemical from underground mineralized water

Summary

The effect of a chlorine-containing chemical prepared by electrolysis from underground mineralized water on the chemical and bacteriological parameters of wastewater was studied. To conduct an experiment on the disinfection of wastewater samples, a chlorine-containing chemical was prepared by preliminary ultrasound exposure on mineralized groundwater (with a chloride content of 20 g/l) and subsequent electrolysis of this water in an experimental unit with titanium electrodes. The high disinfecting effect of the chemical at the final stage of wastewater treatment has been established. The weak disinfecting properties of chloramines in comparison with hypochlorous acid and sodium hypochlorite have been confirmed.

Key words
