The ponds or basins may range in depth from 1.5 to 5.0 meters. [ 6 ] In a surface-aerated system, the aerators provide two functions: they transfer air into the basins required by the biological oxidation reactions, and they provide the mixing required for dispersing the air and for contacting the reactants (that is, oxygen, wastewater and ...
A settling basin, settling pond or decant pond is an earthen or concrete structure using sedimentation to remove settleable matter and turbidity from wastewater. The basins are used to control water pollution in diverse industries such as agriculture , [ 1 ] aquaculture , [ 2 ] and mining .
The settling velocity, defined as the residence time taken for the particles to settle in the tank, enables the calculation of tank volume. Precise design and operation of a sedimentation tank is of high importance in order to keep the amount of sediment entering the diversion system to a minimum threshold by maintaining the transport system ...
Settling pond for iron particles at water works Settling is the process by which particulates move towards the bottom of a liquid and form a sediment . Particles that experience a force, either due to gravity or due to centrifugal motion will tend to move in a uniform manner in the direction exerted by that force.

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 ).
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).
A retention basin, sometimes called a retention pond, wet detention basin, or storm water management pond (SWMP), is an artificial pond with vegetation around the perimeter and a permanent pool of water in its design. [1] [2] [3] It is used to manage stormwater runoff, for protection against flooding, for erosion control, and to serve as an ...
