Clarifier - Wikipedia

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. Inside the clarifier solid contaminants will settle down to the bottom of the tank where it is collected by a scraper mechanism.
