• Adaptability Comes To A Head With Wastewater Screening Technology

  Adaptable bar screens can automatically adjust their raking speed and screen openings based on flow rates, to take advantage of the finest screening possible in any flow condition.

• Relieving The Pressures Of ‘Flushable Wipe’ Clogs In Public Sewers

  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 Launches Solution For Pump Clogging Caused By Flushable Wipes

  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.

• Is There A Better Way To Screen Wastewater Flows?

  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.

• 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. 

• Duperon FlexRake® Bar Screening System Helps Idaho Farmers Clear Debris For Crop Irrigation

  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.

• Washer Compactor Chute Extends 30ft Vertically, Delivers Dry Screenings Up Multiple Floors Without Additional Components

  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.

• LowFlow® FlexRake Eliminates Rag Bypass

  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.

• FlexRake® Fine Screen Delivers Reliable Performance In California Winery

  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.

• Duperon Operates Flawlessly During Hurricanes In Louisiana

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

• 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.
