Next-gen bar screening system maximises treatment plant resilience

Duperon® has announced the FlexRake® IQ™ Series, an evolution of their original 1990s FlexRake bar screening line. An essential step in preliminary water and wastewater treatment, screening is the process of separating solids and other debris from liquids before treatment for reuse or discharge to local waterways.

The new design of the FlexRake IQ increases debris removal, automatically increasing capacity and speed to accommodate changing conditions. During peak flow conditions, the optional FlexRake IQ2 adjusts the screen itself to provide maximum flexibility.

Today’s extreme weather conditions, changing populations, aging infrastructure, and new solids like “flushable wipes” have challenged civil engineers when sizing the screen for a community’s everyday conditions without causing backups during peak events. The revolutionary design of the FlexRake IQ and IQ2 solves this problem.

“We understood that treatment plant operators require real-time responsiveness to deal with changing conditions in the channel,” commented Bryce Funchion, mechanical engineer at Duperon Corporation.

“We looked at the problem and wondered ‘what if the engineer didn’t have to modify their design to accommodate changing conditions? What if the screen itself adapted to them?’ We created the new design to provide an increased safety factor which assures system reliability during both normal flows and worst-case scenario events.”

The original FlexRake® is a robust, simple solution with a low cost of ownership. By re-imagining the components, the sequence of operation, and the possibility to automatically transform the screen field, the new FlexRake IQ and FlexRake IQ2 improve screening during normal flow while adding responsive features to navigate peak flow conditions without sacrificing the simplicity, ease of operation, and low cost of ownership for which Duperon is known.

Mark Turpin, Duperon Corporation president, believes the FlexRake IQ and FlexRake IQ2 offer real-world solutions for today’s stressed water treatment systems. “We have optimised resiliency by creating more responsiveness in dry and wet weather, maximising solids removal throughout flow conditions, and taking on the heaviest solids loading events. The FlexRake IQ series is designed to provide the greatest range of flexibility over the broadest range of conditions.”

Designed for everyday conditions yet equipped for the unexpected, the new FlexRake IQ and FlexRake IQ2 provide a new level of adaptability for water treatment.
