PPS SERIES Dewatering Press

Extract Liquid From Solid Waste via Compaction

The PPS Dewatering Press extracts moisture from solids by the compaction of slurry against a tubular screen element with perforated round or slotted holes. Solids are retained on the surface areas and liquid is passed through the holes. Compaction occurs as the solids are transported by a screw. The screw is designed so that pressure is gradually increased during transport, which helps in retaining solids.

The PPS can be used in a variety of food industry applications as well as pulp and paper processing. JWC’s test facilities are available to test your sample. Please consult one of our technical sales representatives to discuss your needs.

Applications

  • Fruits and vegetables
  • Paunch
  • Pulp and paper
  • Wood fiber
  • Corn/potato chips
  • Processed foods

Features

  • 304 stainless steel construction provides corrosion resistance and allows the equipment to handle wastewater with lower pH, unlike carbon steel which will rust over time
  • Shaft-mounted TEFC washdown-duty gear drive motor allows washdown at the end of each shift
  • Removable access panels let users see the drum during operation which can facilitate any necessary maintenance and cleaning
  • Adjustable pressure plate and pneumatic controls give operators the ability to set the appropriate pressure to yield desired results based on application

Benefits

  • Drier solids mean reduced transportation costs
  • Increased ability to meet wastewater discharge compliance requirements
  • Helps meet EPA landfill paint filter test requirements
  • Potential to turn a waste stream into a sellable product for animal feed or to a rendering facility
