Low Flow System for Wastewater Screening, Washing and Compacting

Oct. 7, 2019


Low Flow System, a pre-engineered, fully automated preliminary liquid/solids separation system for wastewater treatment applications with average flows of 1 million gallons per day (MGD) or less, and up to 4 MGD during peak flow includes a Duperon FlexRake Low Flow and the new Duperon Low Flow Washer Compactor. 


The Duperon FlexRake Low Flow bar screen has been an effective screening solution for small community applications since 2009. With a front-clean, front-return design that eliminates debris carryover, the FlexRake Low Flow has no jam points or lower sprockets that require below-deck maintenance. The proven SmartLink™ technology lifts or pivots around debris and is made of UHMW, a self-lubricating material that requires very little to no water in the channel. 


The new single-auger Low Flow Washer Compactor has been designed as a companion to the Duperon FlexRake® Low Flow, integrating seamlessly to remove, clean, compress and discharge screenings approximately 10 feet in any direction. With the adaptability of its discharge chute, drain connection, and motor location the new Low Flow Washer Compactor provides a flexible standard design for easy site configuration. 


The packaged system achieves an 80% reduction in screenings volume and a 60% reduction in screenings weight, saving operators valuable handling time and hauling costs. It is also energy-efficient, operating under 1 hp to help municipalities conserve on power costs.
