Wastewater treatment

Wastewater treatment is a process which removes contaminants from wastewater. The resulting effluent, discharged to a water body, has an acceptable impact on the environment. Domestic wastewater, also called municipal wastewater or sewage, is processed at a sewage treatment plant.

Industrial wastewater is often processed at a specially-designed industrial wastewater treatment facility, or at a sewage treatment plant.
In the latter case the industry typically performs on-site pretreatment of the waste, before it is sent to the municipal plant.
Other types of wastewater treatment plants include agricultural wastewater treatment and leachate treatment plants.
