Abstract
A dewatering device for removing entrained solids and debris from a liquid stream includes a housing defining a chamber. An auger has a first end positioned outside the chamber and a second end positioned inside the chamber. A compaction zone includes a first tube fixed to the housing. A second tube is slidably mounted on the first tube. A partition is secured to the second tube and has a first longitudinal position in the housing allowing a solids plug to form in the compaction zone and a second longitudinal position in the housing preventing the solids plug from forming in the compaction zone.
