Definition - What does Clarifier mean?
A clarifier is a settling tank used in a variety of processing industries to separate a liquid substance from a solid one. The solid-liquid mixture is introduced into the tank and allowed to settle over a period of time with the aid of a rake system to guide the solids to the bottom of the tank. The liquid is recovered from the top of the tank while the solids are settled or suspended at the lower end of the tank due to gravity. Clarifiers may have an increased risk of corrosion due to prolonged contact with moisture.
Corrosionpedia explains Clarifier
Clarifiers are also known as settlers, thickeners or flotation cells depending on their applications. They are widely used in petrochemical, mining and paper industries to aid product separation and recovery. Clarifiers operate on two basic design criteria, namely the surface area of the tank and the liquid residence time within the tank.
