Due to its chemical properties and its high reactivity, chlorine is very well suited for the disinfection of water and to help the avoidance of contamination with bacteria and pathogens. Chlorine in water occurs balanced depending on pH; at neutral pH mainly as hypochlorous acid (HClO). Hypochlorous acid is a strong oxidizing agent: its disinfecting effect is based on the irreversible aggregation of protein of viruses and bacteria – similar to the effect of heat exposure. When the pH value increases, the balance in the water moves to hypochlorite (ClO–), which reduces the disinfecting effect.
