​ProTechtor® Centerflow Band Screen

The Kusters Water ProTechtor® Centerflow Band Screen, with its vertical orientation, is an excellent alternative to applications with limited footprint and headspace. Influent flow enters the screen in the middle of the screen frame, and is positively screened as the flow transitions from the inside and passes through the traveling perforated filter belt through the sides and bottom. Optimally spaced lifting tines are attached to filter panels to capture and elevate larger items to the internal discharge point. Screenings are washed off via spray headers and/or a combined motorized brush assembly, and are discharged to an internal flume or screenings washer compactor, which transports the screenings outside of the screen frame. The quality of the screened effluent is drastically improved which in turn improves performance and better protects downstream equipment.
