Abstract
A centrifugal separator is provided with a base and a substantially vertical spindle upstanding from the base. A rotary vessel is mounted on the spindle. A housing is connected to the base and encloses the rotary vessel. A liquid supply duct supplies a liquid to be filtered to the rotary vessel. The rotary vessel has an open top and an upper edge at the open top. The rotary vessel is provided with a filter material and has a weir arranged at the upper edge, wherein the filter material extends upwardly to the weir. The housing has a passageway adjacent to the weir and the passage way communicates with the weir to enable discharge of waste material that is contained in the liquid to be filtered and does not pass through the filter material during supply of liquid to be filtered to the rotary vessel and rotation of the rotary vessel.
