The principal objective of wastewater treatment is to allow human and industrial effluents to be disposed of without danger to human health or unacceptable damage to the natural environment. Wastewater from households and industry, commonly together with water runoff from urban areas, is conveyed by the sewerage system to sewage treatment plants ...
The term 'residuals' encompasses the majority of solids generated from the water and wastewater treatment process.

Phosphorus and nitrogen are the two nutrients removed from municipal wastewater. Normally it is only necessary to reduce one of them, and in quite a few cases neither.
Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) are two different ways to measure how much oxygen the water will consume when it enters the recipient. In both cases the oxygen-consuming substances are mainly of organic origin. These substances should be reduced to a minimum in the wastewater treatment plant.
