 The Three Star “Screenings Treatment and Reduction Wash” maintains an impressive compaction ratio and dryness fraction. B.O.D (Biological Oxygen Demand) has been found to be as little as 8mg/g during site trials. Reliability however has been the main priority in the development of the system and the system has been optimised by using proven compaction technology with the addition of pioneering cleaning techniques. A selection of carefully designed alternatives have been created to handle even the most demanding applications cost effectively.
 The STAR Wash can take the place of any compactor mounted under screening equipment or as a stand alone unit fed using launder troughs.
Units can be sized to handle throughput volumes up to 4m³ per hour.
The system uses an Archimedean screw to linearly transfer gross solids from a reception and dewatering zone through a washing section into a compaction zone before eventual discharge.
 Cleaning is undertaken using high pressure water jets located internally (on the Archimedean screw). The liquid is expelled from the transfer member through a plurality of holes at the compaction end and also through a number of slots in the reception zone.
Designed with reliability in mind, the system does not utilise any form of cutter/blade or macerator and is not subject to excessive grit wear.
Available in various body diameters to accommodate varying throughput requirements:
150mm, 200mm and 300mm.
Under Screen System:
Installed in the usual place for a compactor, being fed directly from the screen discharge chute. As situated above the channel coping, the liquid return is achieved using gravity only with a system of pipes feeding back before the screen. The in to out screen orientation allows the compactor to be installed inside the screen so that liquid discharges straight into the upstream flow with no need for pipe work. The recycled solids can be discharged directly back to the main screen surface for re-screening.
Stand Alone System:
Fed by launder trough arrangements using sparge water as a transportation medium. This allows the system to be fd from multiple sources.
