Abstract
An apparatus for removing debris from water in a channel includes a bar screen assembly having a plurality of spaced apart, elongated filter bars arranged in a parallel relationship. A continuous conveyor carries a plurality of rakes. Each rake includes a plurality of spaced-apart tines interdigitated with the filter bars as the rake is moved along the filter bars by the conveyor to remove debris from the bar screen assembly. A conveyor belt retaining system includes at least one guide engaging an upstream side of an inner run of the conveyor and a counterweight connected to the at least one guide for biasing the inner run in a downstream direction.
