What effect does increasing the water temperature have on chlorine's disinfecting ability?

Increasing the water temperature has a positive effect on chlorine's disinfecting ability. As the temperature rises, the kinetic energy of chlorine molecules increases, which enhances their reactivity with microorganisms. This means that chlorine can more effectively penetrate and inactivate harmful pathogens, leading to better disinfection outcomes.

It is important to note that while higher temperatures can increase the effectiveness of chlorine, they may also lead to a quicker loss of chlorine residual due to factors such as increased rates of chemical reactions and the potential for higher rates of evaporation. However, regarding its direct impact on disinfection efficiency, elevated water temperatures generally allow chlorine to work more effectively against bacteria, viruses, and other pathogens.

Thus, the premise of the question aligns with water treatment practices where temperature control is an essential factor in optimizing disinfection processes in water distribution systems.
