Municipal wastewater refers to the contents of sewer systems. It can be made up of both sanitary sewage and stormwater, and can contain suspended solids, disease-causing pathogens, decaying organic wastes, nutrients and over 200 identified chemicals from industries, institutions, households and other sources. Municipal wastewater is released to lakes, rivers and oceans and it must be cleaned before allowing any effluent to enter communal waters. Most countries, municipalities and communities have laws regulating effluents.
A treatment plant should remove any potentially harmful material from the wastewater. The nature of the material and the methods used to remove it often determine its classification. Several steps are required to carry out the removal in wastewater.
