Claim:
1. A centrifugal separator comprising: a rotating body rotating in use in a direction of rotation around an axis of rotation, said axis of rotation extending in a longitudinal direction of said rotating body, said rotating body comprising a bowl, said bowl comprising a base provided at one longitudinal end of said bowl, said base facing a first rear longitudinal area of the centrifugal separator rear of said base; a first outlet passage extending through said base; and a first outlet housing provided in said first rear longitudinal area, said first outlet housing communicating with the first outlet passage to receive liquid from said first outlet passage and said first outlet housing having a first outlet opening discharging in use liquid from the rotating body, said first outlet opening comprising a first weir edge defining in normal use a level of a surface of a liquid in the bowl, wherein said first outlet housing is rotatable around a first adjustment axis whereby the first weir edge is rotatable around the first adjustment axis while maintaining a parallel orientation to the first adjustment axis and the first outlet opening extends an angle between the weir edge and an edge on an opposite side of the first outlet opening, and said first outlet housing comprises a first side wall offset from the first adjustment axis, the first outlet opening being present in said first side wall such that the angle configures the first outlet opening in a direction perpendicular to the first adjustment axis and the weir edge being positionable, via rotation of the outlet housing, relative to a circumferential direction of rotation of the base and the axis of rotation of the rotating body in order to discharge the liquid in an opposite direction relative to the direction of rotation whereby energy is recovered from the discharged liquid.
