Duperon® Harvest FlexRake® Mechanically Cleaned Bar Screens Duperon® Harvest FlexRake® Mechanically Cleaned Bar Screens

The new Harvest FlexRake bar screen from Duperon is ideal for open channel applications with debris that is long, stringy, or matted, such as vegetation or algae. The mechanically simple design of the front-clean, rear-return bar screen uses proven FlexLink™ technology to effectively capture debris without entanglement or wrapping. The Harvest FlexRake screen can withstand side currents, backflow or channel turbulence, and the lower pump bore ensures mechanical engagement and eliminates debris bypass. The system offers a robust lifting capacity that can be customized based on the type of debris and application.

Duperon Washer Compactor Discharge Extension Option Duperon Washer Compactor Discharge Extension Option

The Duperon® Washer Compactor Discharge Extension Option transports compacted debris up to 40 feet in any direction, even vertically, without the energy usage, safety concerns, and layout challenges of a traditional motorized conveyance system. The Duperon exclusive Dual-Auger Washer Compactor™ moves debris using positive displacement, allowing gravity, not side-wall pressure, to provide consistent resistance for effective compaction. The chute, which is customized to the space, acts as a conveyor to guide the compacted debris to a remote receptacle. This solution not only eliminates maintenance requirements but also provides an innovative method for managing compacted screenings without additional equipment.

FlexRake® Sentinel™ PFE FlexRake® Sentinel™ PFE

In 1995, Duperon Corporation created a new screening segment in the wastewater market with the introduction of the Duperon® FlexRake®. The designed simplicity of this multi-rake screen earned its own U.S. Patent for solutions to many operator challenges: no lower sprockets, bearings, or guide tracks for in-channel maintenance; no alignment issues; no jamming; and high operation and maintenance costs. Now, more than 20 years later, Duperon continues to hold that engineered simplicity as its standard of design.

Self-Cleaning Trashrack Self-Cleaning Trashrack

For the toughest debris conditions, the Duperon® Self-Cleaning Trashrack easily handles heavy vegetation, large refuse, logs and other harsh, rugged debris. The front-clean, rear-return technology is able to stand idle for long periods, yet still reliably start whenever a storm or rain event occurs. Independently operating chain strands offer built-in redundancy and continuous operation when it’s most critical.

Washer Compactor Washer Compactor

The Duperon® Washer Compactor is a robustly simple, high-efficiency, non-batching process machine.

    The Duperon® FlexRake®: Inventing A Product That Defined A Segment

    In 1993, the Duperon® FlexRake® entered the market as the first multi-rake wastewater screen to operate without a lower sprocket, bearing or track. Designed by Duperon Corporation founder Terry Duperon, the patented equipment reflected his belief that mechanics should operate as simply as possible. The result was a mechanically-cleaned bar screen that consisted of just three main components — screen, raking device and drivehead. Despite its simplicity, the unit quickly proved to be far more reliable than other, more complicated designs. Paired with the industry’s first five-year warranty in wastewater, the Duperon® FlexRake® soon became a benchmark for low maintenance and ease of operation.

    Duperon Expands Solids Handling Product Line With Washer Compactor Discharge Extension Option

    Since the beginning, Duperon has collaborated with customers to provide customized solutions for site-specific applications. Our most recent development to follow in this tradition transports debris up to 40 feet directly from the discharge of the washer compactor. The Duperon Washer Compactor Discharge Extension Option entered development when we heard several customers describe the difficulty of conveying screenings. While their applications varied — some required vertical conveyance, some had a limited footprint for operations, some had had enough of the frequent jams of their vertical conveyors and some others needed a long horizontal run — their difficulties with current solutions were shared.
