Low Flow System

The Low Flow System is a pre-engineered, fully automated system for applications with average flows of 1 MGD or less, and up to 4 MGD peak flow. Proven SmartLink technology is paired with a single auger washer compactor to seamlessly remove, clean, compress and discharge screenings 5 ft CL in any direction.

Single Auger Low Flow System

    Duperon® Low Flow System 

    Over 80% of treatment plants in the country are rated for 1 MGD or less. Small community wastewater systems are often resource and budget constrained but their headworks still plays an important role in the treatment process.

    The Duperon FlexRake® Low Flow was introduced in 2009 and has been an effective screening solution to serve this market. We are excited to announce the launch of our Low Flow Washer Compactor Companion – perfectly sized and priced to integrate with the FlexRake Low Flow for a competitive yet superior-performing system.

    Like all Duperon products, the Low Flow System is a solution that is simple in design, requires minimum maintenance and delivers a low cost of ownership.
