The system may consist of a single pond or several ponds in a series, each pond playing a different role in the removal of pollutants. After treatment, the effluent may be returned to surface water or reused as irrigation water (or reclaimed water ) if the effluent meets the required effluent standards (e.g. sufficiently low levels of pathogens ).
Facultative lagoon (polishing pond) providing tertiary treatment after a constructed wetland in Hamburg-Allermöhe, Germany. Overflow from the facultative lagoon may be routed through one or more polishing ponds supporting lower populations of anaerobic micro-organisms and a higher proportion of aerobic organisms adapted to survival in lower concentrations of organic material.
Low-level radioactive waste leach pond for the Idaho National Laboratory test reactor. A waste pond or chemical pond is a small impounded water body used for the disposal of water pollutants, and sometimes utilized as a method of recycling or decomposing toxic substances. Such waste ponds may be used for regular disposal of pollutant materials ...
The liquid level is composed of grease, scum and other particulates. [8] The liquid level CAFO wastewater enters at the bottom of the lagoon so that it can mix with the active microbial mass in the sludge layer. These anaerobic conditions are uniform throughout the lagoon, except in a small surface level. [11]

Milking parlour wastes are often treated in admixture with human sewage in a local sewage treatment plant.

"My bathroom is just full of everybody's feces. The tub, filled with feces. There's mildew, mold coming down the wall," Shepherd said. Shepherd (pictured below) lives in the apartment with her ...
A treatment pond is intended to provide wastewater treatment to achieve a certain effluent quality. Ponds are depressions holding water confined by earthen structures. Kinds of treatment pond include: Aerated lagoons rely upon mechanical aerators providing oxygen to reduce the organic content measured as biochemical oxygen demand (BOD).
