Lesson - Chloramination

Chloramination is a process used as an alternative disinfection process in place of free chlorine. An operator’s decision to use chloramine in place of chlorine depends on several factors, including the quality of the raw water, the ability of the treatment plant to meet various regulations, operational practices, and distribution system characteristics. Chloramines have proven effective in accomplishing: 

1. reducing the formation of THMs and other DBPs;
2. maintaining a detectable residual throughout the distribution system;
3. penetrating the biofilm in the pipeline and reducing the potential for coliform regrowth;
4. killing or inactivating heterotrophic plate count bacteria; and
5. reducing taste and odor problems
