The SPIRALIFT SLV fits in extremely tight locations suchas pump stations’ wet wells. It is typically supplied with a TASKMASTER grinder to pre-condition the solids. Afterthe solids are reduced by the TASKMASTER grinder, they flow into the screen area. The solids are swept from the semicircular perforated screen by brushes mounted on the perimeter of the rotating auger and conveyed vertically upthe unit’s transport tube. As the solids are conveyed upthe screw, liquids drain back into the flow. An optional compaction zone can be provided for further dewatering.
