Abstract
Decanter-type separating apparatus comprising within a rotatably mounted tapered and cylindrical barrel a solids-transporting screw rotating at a speed different from the barrel speed, the aforesaid apparatus being characterized by the screw having in an intensive clarification region a pitch substantially greater than used in the past, to stabilize the flow as far as possible and to obtain particularly effective and efficient clarification. In the intensive clarification region, the pitch is much greater than ten degrees and preferrably is within a range of forty to fifty degrees, in certain cases on the order of up to sixty degrees.
