OVIVO® Screw Compactor

Available in 5 standard sizes the Ovivo® Screw Compactor loading capacity ranges between 0.5 and 9.5 (M?/Hr) and launder flows up to 8.0l/s. It can receive flows from dry or water powered launders and incorporates a 9mm thick drainage trough for ruggedness and 6mm tapered holes for improved drainage.
  • Robust reliable machine
  • Minimum energy consumption
  • Low maintenance
  • Minimum operator input
  • 25 year design life

The Ovivo® screw compactor incorporates the originalJones+Attwood™ features that have a proven record ofreliability and robustness. Our new design now receives ?ows from water powered launders and incorporates a 9mm thick drainage trough for ruggedness and 6mm TAPERED holes for improved drainage– built with lowering TOTEX in mind.

  • Low operational cost
  • Reduced carbon footprint
  • Reduced water to solid content for efficient transportation
  • Low capital cost

To meet current market requirements for a simple, robust method of dewatering screenings Ovivo have developed their original design of screw compactor which was first launched in 1986. The new machine retains the original 9mm thick body and trough but now includes additional drilled taper holes in the trough which allows the compactor to accept screenings directly from a water powered launder system. The compactor retains the simplicity and robustness of the original design with a single screw, bearing and drive unit which will ensure a long life with minimal maintenance. 

The Ovivo Screw Compactor is suitable for screening from inlet or sludge screens and is available in a range of sizes from 150mm to 500mm diameter The largest machine can process up to 9.5m³/hour of screenings

What size are the drainage holes?

The Ovivo Screw compactor incorporates 6mm diameter drainage holes. The holes are tapered to improve the drainage rate and efficiency of the compactor.

How to replace the drainage trough?

We would not expect to replace the 9mm trough during the life of the Ovivo Screw Compactor. The drainage trough is fabricated from 9mm thick mild steel. This design feature is very different from most other compactor types, which use 2-3mm thick stainless steel troughs. Unless the screw compactor is maintained correctly these troughs would show signs of extreme wear over a period of time and eventually fail. We would not expect this from the Ovivo Screw compactor.

What is the maximum capacity of the compactor?

Available in 5 standard sizes the Ovivo screw compactor loading capacity ranges between 0.5 and 9.5 (M³/Hr)and launder ?ows up to 8.0l/s
