What effect does an increase in water temperature have on disinfection action?

An increase in water temperature positively affects disinfection action primarily because higher temperatures enhance the efficacy of disinfectants, such as chlorine, by increasing their reaction rates with microorganisms. Warmer water often allows disinfectants to be more effective at killing pathogens since the chemical reactions necessary for disinfection occur more rapidly.

For example, in the case of chlorine disinfection, elevated temperatures can lead to increased chlorine demand due to faster reactions with organic materials and microorganisms in the water. This means that when disinfecting at higher temperatures, operators might find that they can achieve a higher level of disinfection efficiency compared to colder water temperatures.

In practical terms, this relationship suggests that during the warmer months or in warmer climates, water treatment facilities may see improved performance of their disinfection processes, leading to more effective microbial inactivation. This makes it particularly important to monitor and adjust disinfection protocols to ensure that water quality remains compliant with health standards during periods of temperature variation.
