Sedimentation Tank Design Parameters - The Constructor,Sedimentation is the process of removing suspended coarser particles in water by settling down them to the bottom of tank. For a particle to settle down, the flow velocity must be reduced. This process is carried out in a structure called sedimentation tank or settling tank.

Types of Primary Sedimentation Tanks - Rectangular ,Primary Sedimentation takes place in the sedimentation tanks with the objective to remove readily settleable solids and floating materials and thus reduce the suspended solids content. The removal rate is 50-70% of suspended solids and 25-40% of BOD whereas, generally more than two rectangular or circular tanks are used.

Types of Sedimentation Tanks used in Water Treatment,Types of Sedimentation Tanks based on Methods of Operation Fill and Draw Type Sedimentation Tank. In case of fill and draw type sedimentation tank, water from inlet is stored for some time. The time may be 24 hours. In that time, the suspended particles are settled at the bottom of the tank. After 24 hours, the water is discharged through outlet.
