VOLUTE™ dewatering press - ES-051

VOLUTE logo red

The smallest mechanical sludge dewatering press in the world

This small multi-disc screw press, ES-051, will provide economic benefits to wastewater treatment plants, for whose the sludge disposal or transportation cost is exceptionally high due to remoteness of the facility where the wastewater is produced, such as cottages, military camps, and others.

  • Throughput above is calculated as approximate and may vary depending on sludge condition. For model selection, please contact us.
  • Throughput of each model is based on sludge cake with solid content higher than 15%.
  • There is no certain upper limitation on inlet sludge concentration, however, the target sludge must be flowable.
  • Throughput of DAF Sludge is based on sludge containing much fat, oil, and grease such as meat processing applications etc.
  • Throughput of Mixed Sludge (Primary Sludge and Waste Activated Sludge) and Aerobically Digested Sludge is based on sludge containing 20% fi­ber (150 micron mesh clearance) against Total Solids.
