Operators are excited about Lakeside’s new Raptor Multi-Rake Bar Screen, which offers high performance, low maintenance and rapid removal of solids. Manufactured in the U.S. to Lakeside’s design and quality standards, this screen is ideal for wastewater treatment plants, pump stations and combined sewer systems to effectively prevent the harmful effects of inorganic solids to downstream equipment.

Screen Operation

When wastewater flows through the screen, solids are captured on the face of the screen bars. As debris collects and blinding occurs, the upstream water level rises to a high level set point, which then activates the drive mechanism to start a cleaning cycle.

Multiple rakes, attached to dual stainless steel roller chains, provide rapid debris removal from the bar screen. Drainage occurs while material is transported up the screen and dead plate.

Located near the top of the machine, a scraper assembly wipes the debris from the rake head and into a discharge chute. Material falls from the chute into a conveyor, washer compactor or dumpster for disposal.

High Hydraulic Capacity, Low Headloss

The heavy-duty design of the Raptor Multi-Rake Bar Screen provides durability and long life in the most severe conditions. With multiple rakes cleaning the screen and rake teeth penetrating the bar openings, captured material is removed rapidly and efficiently in all applications with a high screenings load.

Design and Construction

The Raptor is engineered using all stainless steel materials to resist corrosion for optimum performance. There is minimal headroom needed above the operating floor, and it features rectangular or trapezoidal screen bars with 3/16-inch minimum bar spacing.

Other features include replaceable rake teeth; maintenance-free lower chain guide or optional lower sprocket assembly; automatic reversing feature; removable stainless steel covers for odor control; optional hinged support to pivot screen out of the channel; and optional explosion-proof design or weather protection system.

Applications

Operators and consulting engineers agree that the Lakeside Raptor Multi-Rake Bar Screen provides superior performance in continuous cleaning and removal of inorganic solids in municipal and industrial wastewater treatment plants, pump stations, surface water intake structures and combined sewer overflows.
