Wastewater collection and treatment have greatly reduced the number of outbreaks of disease in the United States each year. Wastewater treatment consists of a combination of biological, chemical, and physical processes to degrade organic and nitrogeneous wastes and destroy or inactivate a large number of pathogens. Usually, chlorine or chlorinated compounds, ozone, or ultraviolet light is used to disinfect the treated effluent before its discharge to receiving waters.
