Abstract: A solid-bowl screw centrifuge includes one or more discharge weir(s) for discharging clarified liquid out of a drum which has a rotational axis and a rotational direction. The centrifuge has one or more through-opening(s) in a drum cover, each of which is associated with a weir plate having a recess.

The discharge channel is designed such that exiting liquid is conducted over the base of the discharge channel to an overflow edge. The base of the discharge channel to the overflow edge is inclined inwards in the rotational direction relative to the tangential direction by an inclination angle ??0 at the point of the overflow edge.

Abstract: A method for lowering the pressure inside the hood interior of a separator arrangement with a separator with a rotatable drum includes rotating the rotatable drum about a vertical rotation axis. Before processing a product that is to be processed, a liquid is first directed through the drum and the pressure inside the hood interior is lowered, by a device, as a result of rotations of the drum in the manner of a jet pump. After the pressure inside the hood interior has been lowered sufficiently, then the actual processing of the product that is to be processed is performed.
