Managing Disinfectant Residuals in Water Distribution Systems
Maintain minimum residual levels in the distribution system to meet regulatory compliance
Distribution system water quality is a primary factor in balancing regulatory compliance and customer satisfaction. Operators must carefully regulate disinfectant residual in drinking water while reducing the potential for disinfection byproduct formation. Traditional operational procedures to manage disinfectant levels in the distribution network are costly and time consuming. Monoclor® RCS chloramine management system is an intelligent, automated disinfectant boosting system that gives operators the ability to set, control and cost-effectively maintain residual levels in water storage tanks and key locations in the distribution system.
What is the chlorine limit in drinking water?
Chloramines, also known as secondary disinfection, are commonly formed when ammonia is added to chlorine to treat drinking water. They generally provide longer-lasting disinfection as the water moves through distribution pipes to the tap. The US EPA has set Maximum Residual Disinfection Level Goals (MRDLG)—that is, the level of a drinking water disinfectant below which there is no known or expected health risk—for chlorine and chloramine. For both disinfectants, the federal MRDLG is 4 parts per million
