WaterGuard is a liquid chlorine solution in the form of sodium hypochlorite, used as a disinfectant
WaterGuard (also know as Sur’Eau in French-speaking regions) is marketed as an easy-to-use disinfectant for water. This disinfectant chemical is relatively safer and does not require a complex storage system, unlike traditional gas chlorine systems.
