Introducing the Duperon® Dual Auger System

Duperon’s Solution to Flushable Wipes

Dual auger system

A New Option for Managing Flushable Wipes Without Grinding or Chopper Pumps:

  1. Drastically reduces clogged pumps 
  2. Simple 5 in 1 System: capture, dewater, compact, convey and store screenings all with one piece of equipment.
  3. Addresses the problem at its source: deploy at high-ragging sites experiencing pump clogging to remove problematic debris before downstream equipment can be impacted
  4. Compact footprint: can be installed in manhole & wetwell applications as small as 17 inches.
  5. Eliminates emergency maintenance: replaces it with planned (scheduled) and infrequent pickups

    Duperon® Dual Auger System

    Wipes wreak havoc in collection systems and downstream treatment when not removed… What if you could remove the wipes before a small problem becomes a big systemwide risk?

    Operators no longer have to compromise between manually cleaning clogged pumps or using maintenance-intensive grinders that send debris downstream only to re-weave and become problematic again. Our design uses three proven Duperon technologies to capture and remove rags and other pump-fouling debris while keeping organics in the collection system.

    INTRODUCING the Duperon Dual Auger System, a simple and compact screen that removes the majority of wipes and rags in the collection system. By removing non-dissolvable solids at (or near) the point they enter the sewer network, the Dual Auger System restores systemwide integrity by allowing the treatment process to operate as it was designed, unimpeded by wipes.

    … all with the simplicity and reliability that you have come to expect from Duperon.

    Duperon® Dual Auger System Key Features

    The Dual Auger System builds on three proven Duperon technologies:

    1. Positive displacement dual augers continuously clean the inlet by capturing and lifting solids
    2. Brushless self-cleaning eliminates maintenance
    3. Discharge extension chute conveys compacted debris without full length augers

    Built-in Bypass eliminates sewer backups during power outages

    Duperon® Dual Auger System General Specifications

    The Dual Auger System is positioned in a wet well or manhole to catch the falling waste stream from the inlet pipe.  The screening unit is comprised of two vertical counter-rotating augers driven by an electric motor. The motor is completely sealed in the upper housing. The Dual Auger System is fully submersible. 

    There is an overflow bypass opening ahead of the screening unit. The vertical bar screen has a .71 inch bar opening with other size options available.  As screenings are captured, a discharge chute extends vertically to compact, dewater, lift, and store debris, without additional augers required. The solids are held in the chute or discharged into a bin, fully contained for odor control and aesthetics. Debris management is simple, with planned and infrequent pickups to dispose of solids.
