What application is used for injecting chlorine into inlet raw water?

Chlorine is primarily injected into inlet raw water as a disinfectant to destroy bacteria and other microorganisms before the water undergoes further treatment processes. This initial step is crucial, as it helps ensure that harmful pathogens are eliminated early, contributing to the overall safety of the water supply. By addressing potential biological contaminants at this stage, the treatment facility can help prevent public health risks associated with drinking water contaminated with disease-causing organisms.

While other applications of chlorine are important—such as post-treatment disinfection to maintain water quality during distribution—you must consider the context of the question, which specifically relates to the injection of chlorine into raw water. The focus is on preventing bacterial contamination before treatment takes place. Reducing water temperature or addressing taste and odor are not applicable functions of chlorine injection in this context.
