FlexRake IQ®
Responsive Resiliency
A simple solution to smarter raking for responsive resiliency
A smarter way to screen
Our customers are experiencing increased demands and looking for more resilient solutions. One-hundred-year storms are occurring more frequently with bigger peaking events. There is increased inflow and infiltration (I&I) from aging infrastructure. “Flushable” wipes, grit and first flush debris add stress on treatment systems. Even the coronavirus pandemic is changing wastewater composition and diurnal flow patterns. Duperon recognized systemwide resilience begins at the headworks and a new level of raking was required to meet today (and tomorrow’s) plant challenges.
Introducing the new FlexRake IQ®
An intelligent screening system that knows what to do and when to do it.
Designed with a patent-pending sequence technology that delivers 4 times greater debris removal. The FlexRake IQ enhances solids handling by sensing conditions and speeding up – or slowing down – to accommodate changing debris and flow in real time. The scrapers have an enhanced tooth profile and unique collection geometry that handle stones and remove solids cleaned at the higher speed. Large debris is still managed without shutdown and the re-imagined FlexLink™ system ensures that scrapers return to cleaning the screen field faster.
The FlexRake IQ makes these adjustments automatically, without operator intervention. System function returns to normal as soon as operating conditions allow, extending the life of mechanical components.
The original FlexRake® transformed preliminary liquids/solids separation with its simple design that had no in-channel maintenance and ability to adapt to debris. In the tradition of Duperon simplicity, we are now offering a new level of resilient screening. With the FlexRake IQ, we have reimagined components and sequencing to improve screening during normal flow while sensing and responding to solids events…without sacrificing the simplicity, ease of operation, and low cost of ownership associated with Duperon technology.
The FlexRake IQ: designed to deliver a greater range of flexibility over the broadest range of conditions.
Applications:
- Pump stations
- Influent bar screens
- Municipal headworks
- Combined sewer overflow facilities
- Industrial applications

Increased debris removal
Up to 4x the debris removal capacity
Enhanced debris management
Improved grit/rock handling
Process resiliency
With reliable continuous cleaning; Jam Evasion™ Technology and rapid re-engagement, the FlexRake IQ can remove large debris without disruption and re-enter into the bar screen quickly to avoid blinding, flooding, and bypassing
Long product life
The re-imagined FlexLink™ is designed for long life at higher speeds
Description
A new level of resiliency is required to meet today’s known plant challenges and prepare for tomorrows. The FlexRake IQ Platform tackles high peaking factors due to extreme weather and menacing debris like “flushable” wipes, first flushes and settled solids. This is accomplished by system improvements and a patent-pending sequence of operations that automatically responds in real-time to optimize the screen field.
The re-imagined design of the FlexRake IQ focuses on smart enhancements to the raking device to manage heavy solids loading events with 4x increased debris removal capacity, improved grit and rock handling, and greater solids capture.
The FlexRake IQ is an intelligent screening system that knows what to do, and more importantly when to do it without operator intervention.
