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 first pond biome in a series of stabilization ponds digests the putrescible solids suspended in the wastewater being treated. Anaerobic ponds allow solids to settle down at the bottom as sludge. This settling removes a portion of the particulate organic material. [14] A large fraction of the settled solids will accumulate close to the point ...
Figure3: Typical batch-settling column test on a suspension exhibiting zone-settling characteristics. The settling particles can contact each other and arise when approaching the floor of the sedimentation tanks at very high particle concentration. So that further settling will only occur in adjust matrix as the sedimentation rate decreasing.
A sediment trap is a temporary settling basin installed on a construction site to capture eroded or disturbed soil that is washed off during rain storms, and protect the water quality of a nearby stream, river, lake, or bay. The trap is basically an embankment built along a waterway or low-lying area on the site
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.

The clean-up of tailings ponds, which "have sprawled to cover an area the size of Kelowna", which is 211.8 km 2 (81.8 sq mi), represents a "significant part of the liability." [ 15 ] The journalists working on the Price of Oil series were told by experts that the liabilities in the oilsands, mainly tailings ponds, represent almost 50% of the ...
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.
