Gravity Batch sedimentation Continuous

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.
