FEATURED PRODUCTS

Pre-engineered, fully automated, low maintenance system for applications with average flows of 1 MGD or less; and up to 4 MGD. Proven FlexRake technology is paired with a perfectly-sized washer compactor to seamlessly remove, clean, compress and discharge screenings 10 ft in any direction.

The new Shaftless Screw Conveyor from Duperon is ideal for screening and transporting debris in wastewater and industrial applications. Its compact and simple design effectively moves materials with low energy consumption and low maintenance. The Shaftless Screw Conveyor saves operator time and eliminates manual operations by fully automating screenings handling to the dumpster. The conveyor is designed to handle screenings up to 50 cubic feet per hour.

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.

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.

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.

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.

The Duperon® Washer Compactor is a robustly simple, high-efficiency, non-batching process machine. The unique positive displacement, dual-auger system provides Adaptive Self-Regulating Compaction for consistent pressure in variable debris conditions, assuring efficient compaction of debris regardless of changes in flow and debris type - even for non-standard wastewater debris such as rocks, clothing, concrete, and metal up to four inches.

  • Solving Pump Clogs Without Spawning A Million New Problems

    With all the potential debris running through wastewater collection systems — including higher concentrations of “flushable” wipes than ever — the debate over chopping them to bits, or not, has become a fundamental question for wastewater utilities. Now, new perspectives and new mechanisms are giving wastewater treatment plant (WWTP) operators new opportunities for cutting the wipes problem down to size.

  • Don’t Let Bad Customer Decisions Wipe Out Your Entire Treatment Train

    Flushable wipes are wreaking havoc in collection systems and treatment plants around the globe. While this is not a new issue to those in our industry, COVID-19 has made it a mainstream topic as more households consume disinfecting and flushable wipes. The improper disposal of these down the toilet can have negative impacts on the operating cost and efficiency of an entire collection system and treatment train. Here is how nipping the problem at its source can pay dividends throughout the process.

  • Smart New Approaches To Wastewater Screen Design

    Depending on the age and design of wastewater infrastructure, it is easy for screening performance at the headworks of wastewater treatment plants (WWTPs) to get caught between a rock and a hard place. With so many challenges, what can be done to reduce the high risks of performance inefficiency, costly maintenance, or outright equipment failure? Fortunately, next-generation bar screen designs are poised to address these issues.

  • Is There A Better Way To Cut Sewer Pump Clogs Down To Size?

    Some of the more challenging problems facing sewer systems and wastewater treatment plants (WWTPs) have less to do with wastewater and more to do with debris that has no business being there in the first place. Water Online spoke with Duperon mechanical engineer Steve Dill to learn about more resilient approaches to minimizing costly pump jams by eliminating debris closer to its source rather than just chopping it down to size.

  • 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.
