What are Chloramines primarily used for in water treatment?

Chloramines are primarily used in water treatment as a water additive to control microbes. They serve as a disinfectant, effectively killing bacteria and inactivating viruses in the water supply. Unlike chlorine, chloramines provide a more stable residual disinfectant that remains active in the distribution system for a longer time, helping to prevent microbial regrowth as water travels through pipes and into consumers' homes. This stability is crucial in maintaining water quality, especially in larger systems where water may sit in pipes for extended periods.

Other options do not fit the primary role of chloramines in water treatment. While chloramines can be a disinfection byproduct when chlorine reacts with organic matter, their main purpose in treatment is as a disinfectant. Enhancing taste is not a typical function associated with chloramines, and they are not utilized as cooling agents in water systems. Their efficacy in microbial control makes them an essential component of modern water treatment practices.
