Mechanical Bar Screen

The SSI Mechanical Bar Screen is a Thru-flow rear discharge design that consists of a continuous series of rakes, toothed for engaging the bar rack.  The ends of the rakes shall be mounted on the endless strands of roller chain operating overhead and foot sprockets.  As raw water passes through the bar rack, large floating and suspended debris will be impinged on the upstream rack surface.  When the screen is operated, the rake teeth will engage in the bar rack, lifting trapped debris.  As the rakes continue ascending over the head sprockets, the rakes will discharge all debris into a refuge trough.
 
The bar screens can be manufactured in either carbon or 316 stainless steel.  Inclined angles up to thirty-five degrees can be achieved due to the rigid self contained box structure.  Our design will fit intakes 2 feet to 14 feet in width and up to 106 feet in length.
 
Let SSI intake expertise help you choose the right configuration and debris removal capacity for your unique intake requirements.
