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 and a drive member (4) configured to rotate the centrifuge bowl (10) around the axis of rotation (X) at a rotational speed. The centrifuge bowl (10) further comprises an inlet (11) for receiving the liquid mixture to be separated, at least one liquid outlet (12) for discharging a separated liquid phase and at least one sludge (14) outlet for discharging a separated sludge phase. The centrifugal separator (1) further comprises an intermittent discharge system (30) for intermittently opening and closing the at least one sludge outlet (14). The method (100) comprises the steps of a) rotating (101) the centrifuge bowl (10) at a first rotational speed S1; b) increasing (102) the rotational speed of the centrifuge bowl (10) to a second rotational speed S2 that is higher than said first rotational speed S1, and c) opening (103) the at least one sludge outlet (14) to discharge contents within the centrifuge bowl (10) during rotation at said second rotational speed S2.
