Patent ID: 8887925

Claim:
An asymmetrically profiled wedge bar screen comprised of a plurality of wedge bars used for sweeping flow assisted inertial separation of suspended particles in a fluid, wherein the profile of the wedge bars is a generalized trapezoid, tilted in the direction of the sweeping flow with a distinctly extended trailing edge at the aft face side of the cross section of the wedge bars which is immediately followed with a smooth, plane or curved, side wall with no protrusion into a gap between two adjacent wedge bars and wherein the trailing edge is protruding with a pointed edge into a tangential flow-pattern of the fluid and wherein the trailing edge induces a flow separation and creates localized eddies on a suction side of the trailing edge that shape highly curved fluid flow streamlines and thus creates centrifugal forces required for inertial separation and wherein the gap is larger than the size of the particles separated from the fluid.
