A decanter can be regarded as a sedimentation tank that is wound around an axis. In the sedimentation tank, the solid particles, which are heavier than the liquid, move to the bottom by gravity and form a sediment (solid phase) at the bottom of the tank. For example, a wine decanter can be understood as a kind of sediment vessel. In a centrifuge, the solid and liquid phases are separated by means of centrifugal acceleration. In the rotating bowl of the centrifuge, the solid particles, which have a higher density and are therefore heavier than the liquid, move outwards because of centrifugal force. The sediment is formed on the inner wall of the centrifuge bowl. Since centrifugal forces of approximately 3000 g are exerted in a centrifuge as opposed to 1 g in a gravitational field, the separation of the solid particles from the liquid is much faster and more efficient.
