Abstract

The present invention provides a method (100) of operating a centrifugal separator (1) The centrifugal separator (1) comprises a centrifuge bowl (10) arranged to rotate around an axis of rotation (X) and in which the separation of a liquid mixture takes place, a stationary hood (2) which defines at least part of a surrounding space (3) in which said centrifuge bowl (10) is arranged, a drive member (4) configured to rotate the centrifuge bowl (10) around the axis of rotation (X). The centrifuge bowl (10) further comprises an inlet (11) for receiving the liquid mixture to be separated and at least one liquid outlet (12, 13) for discharging a separated liquid phase. The method (100) comprises the steps of a) separating (101) the liquid feed mixture into at least one separated liquid phase in the centrifuge bowl (10); b) collecting (103) contaminated water from at least one unit of the centrifugal separator (1); and c) resupplying (106) said contaminated water to the centrifugal separator to flush the surrounding space (3). The present invention further provides a centrifugal separation system (200) for separating at least one liquid phase and a solid phase from a liquid feed mixture.
