Abstract
A rotating bowl decanter centrifuge including a clarifier section and a beach section for separating a lighter phase from a heavier phase. The beach section includes a conveyor for conveying the heavier phase toward the exterior of the centrifuge. The centrifuge is without a conveyor in the effluent discharge end of the clarifier section. In a preferred embodiment, the clarifier section has an outward incline angle so that the clarifier wall bends away from the bowl's rotational axis. The beach section includes an inwardly inclined outer wall which bends towards the rotational axis of the bowl. It is preferred that the outward incline angle in the clarifier section be on the order of 5.degree. or less.
