Abstract
This invention provides dredging means having means to screen long slender particles wherein the long dimension extends in the direction of flow through a fluid-flow conduit. The screening means comprises a pair of opposing corrugated surfaces, the folds or corrugations on the opposing surfaces being substantially parallel, and separated by a distance, and having a wave length, determined by the size particle to be screened. Preferably, the corrugated surfaces are formed as a plurality of corrugated plates inserted within and extending along the direction of fluid-flow in a conduit. The axis of curvature of the corrugations or folds extend perpendicular to the flow of the stream.
