The solids form sediment in the liquid, but are not retained by a screen as in a screening centrifuge. The speed of sedimentation can be increased by adding flocculants. In the solid bowl centrifuge the sedimented solids are transported by the scroll to the smaller diameter and discharged, while the clear liquid flows over the adjustable weir at the cylindrical end of the machine.
The screen decanter is a combination of a decanter and a screen centrifuge, which has a screen section to further reduce the final moisture. Material passing through the screen section can be recycled to the centrifuge feed.
