Decanter centrifuge is most often used for clarification of liquid containing high concentrations of solids, removing solids from liquid.
A decanter centrifuge is a sedimentation centrifuge for separation of suspended solids from one liquid.The characteristic which distinguishes a decanter centrifuge from other types of centrifuges such as disc stack separators is that it has a cono-cylindrical rotor equipped with a conveyor for continuous unloading of sedimented solids.
