Abstract
A solid-bowl screw centrifuge has a centrifuge drum that can rotate about a longitudinal axis during operation. The centrifuge drum has a front wall with at least one discharge opening for discharging clarified product from the centrifuge drum. A weir edge is formed at the discharge opening radially toward the outside. An energy recovery device is provided for recovering energy from the clarified product that is being discharged. The energy recovery device defines a discharge pipe through which the clarified product passes as the clarified product flows out. The energy recovery device is situated on the outside of the front wall and in front of the discharge opening that has the weir edge.
