Non-clogging, self-cleaning dual auger design eliminates the need for additional agitation. Augers are interleaved and do not contact each other.

One cleans the other; debris cannot accumulate or wrap.

The Duperon Washer Compactor's second counter-rotating auger interrupts the rotation of debris adhered to the first auger. this approach assures positive displacement - much like a meat grinder. Positive displacement assures the continual movement of all types of debris, from solids and textiles to grease and septage.

Rocks, chunks of asphalt or concrete, large clothing items, and large volumes of septage or grease are not classified as typical wastewater debris, yet any and all of these items can occur with regularity and in any volume in the wastewater channel. That's why the Duperon Washer Compactor has been engineered to take whatever you can throw at it - and still provide you with consistent performance, reliabilty, and long-term value.

Washer Compactor designs get into trouble when the compaction screw is used to dewater debris. Have you ever wrung out a wet dishrag with too much force? It begins to move perpendicular to the twisting force, curling and expanding outward. The same concept applies here: with a compactor's spinning screw, this twisting effect generates an uneven outward force - referred to in technical terms as a "secondary force" or "side-loading". This side-loading can throw an auger completely out of balance (as happens in a washing machine during the spin cycle when the machine is overloaded).

The full negative impacts of side-loading occur just before the pressure at the end of the compaction screw reaches the point of useful dewatering. (In addition, these forces can increase necessary power requirements by as much as 40%.) Though high dry solids content can be achieved using a compaction screw to dewater, it is not sustainable to continuous duty operation.

The wash section of the Duperon Washer Compactor is located outside of the compaction zone and uses flood washing to effectively return organic debris to the waste stream. An additional benefit? Placing the wash section outside of the compaction zone avoids the risk of pressurized contaminants such as grease clogging the flood water port - and eliminates nozzle-related maintenance.

Also, plant water works well in the low pressures of the wash section, saving the expense of using potable water.

Maintenance is simple: simply a monthly visual inspection and recommended gearbox service every 5 years.
