This article is a continuation of “Chlorine‐‐‘Special Agent’ for Disinfecting Water” by Ralph Leidholdt (OpFlow September 1982). In this selection, the author discusses the chemical reactions that occur when chlorine gas, calcium hypochlorite, or sodium hypochlorite is added to water for disinfection purposes. The following chlorine residuals are discussed: hypochlorous acid; hypochlorite ion; monochloramine; dichloramine; and trichloramine. Breakpoint chlorination is also defined and discussed, as well as superchlorination and dechlorination.
