What is the primary function of chloramines in water treatment?

The primary function of chloramines in water treatment is to disinfect water. Chloramines are formed when ammonia is added to chlorine, creating a more stable and longer-lasting disinfectant than chlorine alone. This property makes chloramines particularly effective for maintaining microbial control in water distribution systems, ensuring that harmful pathogens such as bacteria and viruses are eliminated and that water remains safe for consumption over extended periods.

While chloramines do have some minimal impact on water taste due to their residual properties, their main purpose is to serve as a disinfectant. They do not significantly increase pH or soften water as other substances might, which makes disinfecting the primary role of chloramines in water treatment processes. The use of chloramines is especially valuable in long-term water storage and distribution systems, where maintaining water quality and safety is essential.
