Abstract
A system for transporting and dewatering solids in a fluid system. An auger is used to transport solids and provide first stage compaction. A dewatering plate having a restricted opening provides second stage compaction and dewatering. The auger maybe be shafted or shaftless. First stage compaction is achieved by a change in helical pitch of the auger immediately preceding the location of the dewatering plate.
