Chlorine began to be widely used as a disinfectant in the early 1900’s. It revolutionized drinking water treatment and dramatically reduced the incidence of waterborne diseases. Chlorine remains the most widely used chemical for water disinfection in the United States.
===Suitable conditions ===

Each product should have its own instructions for correct dosing. In general, the user adds the correct sized tablet for the amount of water to be treated, following the product instructions. Then they agitate the container, and wait for the amount of time instructed on the package, normally 30 minutes (“contact time”). The water is then disinfected and ready to be used.
Medentech Ltd. manufactures Aquatabs for water disinfection, hospital surface infection control and general environmental disinfection. In Tanzania, PSI imported a single sized 20 litre-tablet that are packed locally in boxes of 36 10 tablet-strips.
