ABSTRACT:
A wastewater screening device includes a perforate screening member through which wastewater flows, including a plurality of laterally spaced apart screening rods interconnected by cross members, such that solids in the wastewater are captured by the screening member. A plurality of wiping elements are positioned between the screening rods and shift longitudinally to clear screenings from the screening member. Each of the wiping elements has at least one end projection disposed laterally between opposite sides of the screening member, and a tapered wiping surface.
