Gravity sedimentation operations thickeners

Sedimentation thickener. The separation of a dilute slurry by gravity settling into a clear fluid and a slurry of higher solids concentration is called sedimentation. Industrially, sedimentation operations are often carried out continuously in equipment called thick-... 

The available gravity sedimentation equipment can be divided into batch operated settling tanks and continuously operated thickeners or claiiiiers. The batch settling tanks are still used where relatively small quantities of liquids are to be treated such as, for example, in spent lubrication oil reclamation and cleaning. The bulk of the processing by gravity sedimentation is, however, in continuously operated thickeners and clarifiers. 

Sedimentation is the separation of suspended solid particles from a fluid stream by the action of a body force on the settling behavior of the particle. The body force may be either gravitational or centrifugal force. This section covers gravity sedimentation, represented by clarification and thickening. The equipment used for these two operations are called clarifiers and thickeners, respectively. Centrifugal sedimentation will be discussed in the next section. 

Sedimentation is the partial separation or concentration of suspended solid particles from a liquid by gravity settling. This field may be divided into the functional operations of thickening and clarification. The primaiy purpose of thickening is to increase the concentration of suspended sohds in a feed stream, while that of clarification is to...
