FEATURED PRODUCTS

A new alternative to grinders and chopper pumps in the collection system and plant headworks: the Duperon Dual Auger system is our solution to wipes.

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.

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.

A front-clean, front-return, mechanically-cleaned bar screen technology. Utilizes stainless-steel tear-shaped bars with 1/4 inch, 3/8 inch, or 1/2 inch openings.

A front-clean, front-return, mechanically-cleaned bar screen technology. Utilizes A36 steel with Duperon® standard coating or hot-dipped galvanized; also available in 304 and 316 stainless steel. Available with 2 inch - 4 inch openings

FEATURED CONTENT

  • The adage about the three most important factors in real estate value — location, location, location — carries a certain degree of truth for wastewater collection systems as well. How close to the source of problematic clogging materials a debris handling solution is installed can be just as important as how efficiently that solution neutralizes them. Here are several ways to evaluate each of those variables and choose the best option.

  • Duperon today announces the commercial availability of the Duperon Dual Auger System (DAS), a solution to pump clogging caused by flushable wipes and other pump-fouling debris.

  • Of all the challenges wastewater treatment plants (WWTPs) face, screening debris from the flow at the headworks is one of the first encountered. Until recently, that has involved choosing one screen size to accommodate both average and peak flows or installing two different screen sizes. Water Online spoke with Duperon Product Manager Bryce Funchion to discuss the possibilities of a new way to get the best of both worlds.

  • 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.

  • 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.

  • 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.

  • 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. 

  • Duperon Corporation, leader in innovative preliminary liquids/solids separation systems, announces that two FlexRake FRHD automated bar screens installed at the Mud Lake Water Users, Inc. (MLWU) irrigation company in Eastern Idaho are successfully protecting MLWU’s 160,000-gallon-per-minute pumps from tumbleweeds and other debris.

  • The West Bay County WWTP, rated for 10 MGD and seeing an average flow of 4.5-6 MGD; prior to the installation of the Duperon® Washer Compactor, the plant collected approximately 20 yards of debris each week.

  • The Roaring Fork Water & Sanitation District WWTP receives residential activated sludge at an ultimate site capacity of 1 MGD. Prior to the 2009 installation of the Duperon FlexRake Low Flow, the plant had operated with a manually-raked bar screen.

  • The McManis Family Vineyard is surrounded by rural land in Ripon, California. All water on-site is courtesy of the vineyard’s own well system. With no access to city facilities, the matter of managing the site’s waste falls to the Duperon® FlexRake® FS Winery Model.

  • When Hurricanes Katrina and Rita struck the Gulf Coast in 2005, the impact was immediate and devastating.

  • 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. 

  • 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.
