Duperon unveils internally fed rotary drum screen at WEFTEC 2023

Designed to manage ultrafine particles, fibres and other difficult-to-capture debris, Duperon Corporation unveiled the first product of its new drum line — the internally fed rotary drum screen — at the Water Environment Federation technical exhibition and conference (WEFTEC). The drum screen is engineered for sites with both high flows and high solids content, and is available for piloting in both municipal and industrial applications.

The drum screen is designed without the use of corrosion-prone trunnion wheels

President of Duperon Mark Turpin said, “We have been working with engineers, managers and operators to ensure [the] product upholds our founding principle of simplicity. We look forward to helping plant operators protect costly equipment and continue serving their communities with minimal disruption.”

For more than 35 years, Duperon has been reportedly providing adaptive screening and solids handling solutions. In drum screening, these pain points have been clogging and corrosion. The Duperon internally fed rotary drum screen addresses corrosion concerns by replacing trunnion wheels with stainless steel shoes and ultra-high molecular weight (UHMW) polyethylene, water-lubricated wear strips. A direct drive system eliminates chains and sprockets and is positioned outside of the wet area to further avoid corrosion. Clogging is minimised with quick release sprayers and an enhanced screen design that is customisable to suit individual treatment needs, including a variety of screen types and openings.

If maintenance is required, the design includes the option for removable panels to access the inside of the drum. No special tools are needed to access these areas, remove or clean sprayers and wear strips, according to a statement.

WEFTEC is held on 30 Sep-4 Oct 2023 in Chicago, Illinois, US. The Duperon team will be at booth #1600 to showcase the new drum screen and its capabilities.
