Duperon FlexRake - Washer Compactor
The only washer compactor that matches the capacity of the Duperon FlexRake. Washer compactors help to automate the solids handling process efficiently and provide a bottom-line impact to meet requirements and reduce landfill volume.
Powerfully simple: providing consistent results in variable flow and debris conditions
The Duperon® Washer Compactor is ideal for debris in wastewater and industrial applications to clean captured screenings, reduce weight, volume, and odors. Since the Duperon® FlexRake® screens can remove large debris, mats, grease, and other irregular items that find their way into the system, our Washer Compactor provides a robust debris management strategy to complete the process.
The patented dual augers provide positive displacement and a self-regulating compaction zone controls pressure, regardless of volume, to deliver consistent results. The Duperon Washer Compactor assures captured solids are washed, compacted, transported, bagged or otherwise discharged to your site requirements.
The Duperon® Washer Compactor patent-pending Discharge Extension Option (DEO) can transport debris up to 40 feet in any direction, even vertically, eliminating the need for additional motor-driven conveyance systems.
Most washer compactors rely on the debris chute for compaction. This consists of pushing debris through a set orifice to dewater, using friction from the chute to compact, and applying high horsepower motors to move the plug. With this type of equipment, extended discharge chutes would result in over-compaction and jamming.
The Duperon Washer Compactor works differently. The dual augers combined with the geometry of the chute layout produce backpressure. This backpressure allows the weight of the plug column (not friction from the chute) to dewater and compact debris. This allows the DEO to easily transport compacted screenings to extended distances, without resistance, additional conveyance augers/mechanisms or large motors. This makes the DEO an excellent option for retrofit applications with challenging constraints.
The DEO provides significant cost savings by:
- Reducing the length of the bar screen extending multiple levels – the DEO transports the debris to the discharge location instead
- Eliminating additional conveyance, motors and associated Operations & Maintenance (O&M) required
- Eliminates manual labor and debris handling of captured screenings
Duperon continues to lead the industry standard with simple engineered solutions for desired outcomes … all with the reliability that you have come to expect from Duperon.
The Duperon® Washer Compactor is a powerful system that uses self-cleaning dual augers in a counter rotation to prevent wrapping and to help separate organic and inorganic materials. The dual augers use positive displacement, to continuously move debris forward for cleaning, compaction, and discharge. Flood washing ports clean screenings and return organic back to the channel. A proprietary self-regulating compaction zone provides consistent pressure regardless of volume and debris composition.
Unlike other technologies, the Duperon Washer Compactor typically compresses debris before it enters the discharge chute so it does not rely on fixed orifice compaction (using the friction of screenings in the chute to compact). The internally controlled compaction allows Duperon equipment to push a plug column with little to no resistance to extended locations. The captured solids are delivered in an enclosed, odor and vector-free chute to the desired discharge point.
The self-regulating compaction zone delivers consistent dry solids regardless of debris or volume and does not rely on friction from fixed sized compaction
