Decanter Centrifudge Manufacturer Decanter Centrifuge is a clarifier whose base is wrapped around a center line. Rotating this unit rapidly means that the effect of gravity is replaced by a centrifugal force – the effect of which can be up to 4000 times greater. This force is then used to separate solids from liquids efficiently in a manner that is easy to control. Depending on the particular configuration and surrounding equipment, a Decanter Centrifuge can be used to separate a wide range of different solids from one or two liquid phases, on a continuous basis.
