A centrifugal separator has for returning separated sludge to the separation chamber of the rotor a recirculation circuit (27, 28, 33, 39, 41, 43, 32, 30, 29) which is completely free of flow restricting nozzles. The amount of separated sludge allowed to leave the centrifugal separator through the outlet conduit (39) without being recirculated is determined by setting valves (22, 40) in the stationary outlet conduits (21, 39) for the separated sludge and clarified liquid, respectively.
