The chlorination of water supplies and polluted waters is used mainly to
destroy or deactivate disease-producing micro-organisms. The Hanna Instruments HI 3831T 0-2.5 mg/L Total Chlorine
Test Kit also serves to improve the quality of drinking waters, as chlorine reacts with ammonia, iron, manganese,
sulfide and some organic substances.
Nevertheless, high amounts of chlorine will produce adverse effects, like formation of compounds which are
potentially carcinogenic (e.g. chloroform) or harmful to aquatic life (e.g. chloramines). Thus it is essential to
control that the proper amount of chlorine has been added in order to fulfill the primary purpose of disinfecting
and to minimize any adverse effects by using the Hanna Instruments HI 3831T.
