The Jacopa® screw compactor is suitable for dewatering sewage screenings to be reused, unwashed, for composting – the high organically loaded screenings encourage the composting process and subsequent conversion of waste to energy.

The Jacopa® screw compactor incorporates the original Jones+Attwood™ features that have a proven record of reliability and robustness. Jacopa's new design now receives flows 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.

It is available in 5 standard sizes with loading capacity ranging between 0.5 and 9.5 (m³/hr) and launder flows up to 8.0l/s.

Typical needs

  • Improved dewatering and resistance to drainhole blockage
  • Minimal operational intervention
  • Reliable 20+ years operational life
  • Low energy requirement
  • Loading capacity of up to 9.5 m³/hr and flow laundering up to 8.0 l/s

Creating value

The Jacopa® screw compactor can receive flows from water powered, or dry launders and create a good quality ‘plug’ (with optional screenings washing). The Jacopa® screw compactor features a flanged opening to accommodate an existing launder channel.

  • Flanged opening for retrofit launder hopper
  • Minimal operational intervention – low operating costs
  • 25 year design life
  • 5 standard sizes

A suitable retrofit for most OEM screening compactors, the Jacopa® screw compactor features 6mm tapered holes for improved drainage which enable it to receive feed directly from screens, conveyors and the higher water volume launder flow from installations that previously required screenings to be washed.
