OVIVO® Screw Compactor

The Ovivo Screw Compactor is suitable for screening from inlet or sludge screens and is available in a range of sizes from 200mm to 500mm diameter. The largest machine can process up to 10m³/hour of screenings

The Ovivo Screw Compactor is suitable for screening from inlet or sludge screens and is available in a range of sizes from 200mm to 500mm diameter. The largest machine can process up to 10m³/hour of screenings.

Screenings can be delivered to the screw compactor by conventional conveyor systems or by the more efficient washed launder method. The screw compactor can also sit directly beneath the screen discharge and process the solids immediately at the screen. Drainage of the liquors from resulting from the machine/s are diverted to the works drainage system or directly back to the incoming flow of effluent.

The Ovivo® Screw Compactor incorporates the original Jones+Attwood™ features that have a proven record of reliability and robustness.

Ovivo J&A Screw Compactor Features include:

  • High quality construction form stainless steel.
  • Robust screw operating in a perforated plate trough.
  • Designed to accept water-borne solids from screen systems.
  • The dewatering screen is cleaned automatically by the spiral mounted brush.
  • Exclusive, steady bearing fitted at the discharge and compaction end of the screw.
  • High rated, drive end, thrust and radial bearing.
  • High capacity mech/elec drive system with ample overload capacity.
  • Internal machine wash system with auto on/off flow control.
  • A range of outlet chute arrangements to suit most collection methods

•  Screw compactors with increased capacity are available. Increased screw speeds and correspondingly increased motor powers are necessary. Please refer any special requirements to Ovivo.

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
