Thickeners are essentially clarifiers producing a clearer over flow. disturbance of the medium water through which the solid particles are allowed to settle.
Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and or thickening.
