Internally Fed
Drum Screen
We didn’t reinvent the wheel. We removed it. An innovative drum screen design without trunnion wheels.
Introducing the Duperon® Drum Screen
The Duperon Internally Fed Rotary Drum Screen, the first of our Drum Line products, applies proven Duperon simple adaptive screening technology to fine screening for municipal and industrial applications. Engineered for sites with both high flows and high solids content, the Duperon Drum Screen is designed to manage difficult-to-capture debris and protect sensitive treatment processes, such as MBR, from fine particles and fibers, making it ideal for both wastewater and industrial applications. As with all Duperon products, the Duperon Drum Screen combines mechanical simplicity, trouble-free maintenance, and long product life for treatment process reliability and increased efficiency.
The Duperon Internally Fed Rotary Drum Screen is only available to sites through our Pilot Program. Learn more about our Pilot Program here.
Applications:
- Wastewater with MBR
- IFAS
- MBBR
- Pulp and Paper Mills
- Food and Beverage
- Vegetable processing
- Meat processing
The Duperon®
Difference
The Duperon®
Internally Fed Rotary Drum Screen
Long product life
The unique design eliminates the need for trunnion wheels, sprockets and chains, which reduces the wear and tear points and increases the product’s lifespan.
Trouble-free maintenance
All routine maintenance is done at chest level. Removal of the drum is not required to perform maintenance and manual clean in place (CIP).
Designed for duty
Engineered to perform in fine screening applications that have high flows and high solids loading.
Flexible design
Quick change-out screening panels available in various opening sizes, allows for improved debris management.
Low cost of ownership
With few wear parts, a fractional horsepower motor and minimal maintenance required, Duperon equipment is easy to install, own, and operate.
Customizable
The water inlet can be designed on either side of the drum screen, providing options for difficult installation scenarios.
Description
The Duperon Internally Fed Rotary Drum Screen utilizes a direct drive system to eliminate the use of belts, chains or sprockets. A combination of stainless-steel shoes and UHMW polyethylene wear strips replace the use of trunnion wheels reducing labor intensive maintenance. The screening panels remove easily for regular cleaning and to allow access inside the drum without disassembling the machine.
Screening panels are available in wedge wire, perforated plate and wire mesh in various opening sizes to optimize debris removal.

Case Studies
Crockery Township Case Study – Internally Fed Rotary Drum Screen
Duperon’s Internally Fed Drum Screen replaced two fine influent screens and flawlessly provided screening during a transitional period at a plant and required no maintenance.
Join the drum screen pilot program
Try out the Duperon® Drum Screen at your site with our Pilot Test Program. Both municipal and industrial sites may participate in this 2-6 week program to gain valuable information on the type and volume of debris your site manages.
Our portable, skid-mounted Drum Screen system comes with controls and multiple screen panel options.
Duperon will deliver and assist with the set-up of the Drum Screen, provide operational training, sampling assistance, analysis of sample data, and a final test report. The data derived from the sample tests provides valuable information to ensure your site has the screening system in place to provide system-wide resiliency.
