Abstract

Slurry to be densified by removal of water is passed into an inlet of a housing, through the housing, and out an outlet. Inside the housing are a plurality of elongated hollow filter elements, which extend in the direction of flow of the slurry. Water in the slurry passes through the walls of and into the interiors of the hollow filter elements, as the slurry flows along the lengths of the filter elements. The cross-sectional area of the flow space for the slurry, defined between the exterior surfaces of the filter elements and the interior wall of the housing, decreases as one proceeds along the lengths of the filter elements. As a result, the flow speed of the slurry does not decrease proceeding in the flow direction, but instead is maintained at least substantially constant, or is even caused to increase (accelerating flow). Accordingly, the densified slurry flowing along the exterior surfaces of the filter elements, because its flow speed is constant or even increasing instead of decreasing can wash away solid particles which would otherwise tend to accumulate on the exterior surfaces of the filter elements.
