Public water systems that use source or ground water under the direct influence of surface water are required to disinfect water. Potable water carried from a centralized treatment plant or wells to the point of use is required to meet specific chlorination standards. Most treatment plant operators chlorinate water using either chlorine gas, liquid sodium hypochlorite solutions or dry calcium hypochlorite.
The disinfectants used to treat public water unleash the power of chlorine chemistry to destroy harmful bacteria and viruses. Public water utilities must meet strict requirements for dosing equipment and monitoring their chemical usage. A chlorine dose too low may allow regrowth of disinfectant-resistant pathogens, excessive biofilm development in distribution systems, or an unpleasant taste in the water. A chlorine dose too high may cause taste and odor problems, distribution pipe degradation, unnecessary disinfection byproducts, and health problems.
Evoqua offers solutions to keep potable water at safe disinfection levels. We provide municipal treatment plants with equipment and services that allow for safe, consistent disinfectant doses. Our chlorine dosing and monitoring equipment can be used by plants of all sizes that use any chemicals to achieve chlorinated water.
