Difference Between Clarifier and Thickener

The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not. The ...

Sedimentation also helps to determine the medical conditions of a person. Sedimentation rate of RBC’s is an example. The sedimentation rate is performed by measuring how long it takes red blood cells (RBCs) to settle in a test tube. As time passes, RBC’s start to separate from the other plasma contents, and they settle down at the bottom ...
