Sedimentation tank | water treatment | Britannica.com

Sedimentation tank, also called settling tank or clarifier, component of a modern system of water supply or wastewater treatment. A sedimentation tank allows suspended particles to settle out of water or wastewater as it flows slowly through the tank, thereby providing some degree of purification.

Activated Sludge Process Activated Sludge Wastewater ...

Is defined as a 'Suspension' of microorganisms, both living and dead' in a wastewater. The microorganisms are active by an input of air (oxygen) thus known as activated-sludge. Activate-sludge is that sludge which settle down in a secondary sedimentation tank after the sewage has been freely aerated and agitated for a certain time in an Aeration tank.

Sedimentation and Clarification Sedimentation is the next ...

Pre-Sedimentation Not all systems use pre-sedimentation, but pre-sedimentation is often used when raw water turbidity is high or highly variable. Pre-sedimentation basins range in size, depending on the flow, and the water is sometimes pre-treated with a coagulant and/or a polymer prior to entering the pre-sedimentation basin (AWWA, 1999).

Sedimentation - Wikipedia

Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism.In geology, sedimentation is often used as the opposite of erosion, i.e., the ...
