Abstract
A burden removal system for removing solid burden from a stream of water. A screen has an upper and a lower surface with pores extending between them. The upper surface is substantially horizontal. A drive bar with a wiper bade is cyclically bi-directionally driven with the blade pushing burden along the upper surface in one direction and rising above the burden in the opposite direction. Jet sprays discharge water against the lower surface, preferably just ahead of the wiper blade to assist the blade in moving the burden and cleaning the pores.
