Definitions for "COMBINED CHLORINE"
Chlorine that is combined with a nitrogen compound, usually ammonia forming compounds known as chloramines. Combined chlorine is far less effective than free chlorine in the killing of bacteria and control of algae.
A reaction product between hypochlorous acid and nitrogen compounds such as amines from bather pollution.
Undesirable, foul-smelling, body-irritating compounds formed when insufficient levels of free available chlorine react with ammonia and other nitrogen-containing compounds (swimmer and bather waste, fertilizer, perspiration, urine, etc.). Combined chlorine is still a disinfectant but it is a much weaker, ineffective form of chlorine.
