The Screw Compactor body is manufactured in a tubular form to accommodate the Reduced Screw flight, which is driven by a heavy duty Inline Helical Bevelled Gearbox.

The Compactor Screw Press body consists of two specific zones, namely the inlet zone and compaction zone. Screenings are discharged into the inlet zone. The inlet zone consists of a perforated half cylindrical tube with an inlet chute, with water supply being optional. All excess water is drained off. The screenings are then transported, through the use of a reducing pitched screw ribbon, into the compaction zone. The compaction zone consist of a perforated cylindrical tube equipped with a water supply for cooling and washing of the screenings. A reducer is mounted at the end of the compaction zone in order to generate backpressure on the screenings. The shaft of the screw ribbon is extended to the reducer and is tapered down.

The back pressure ensures that the fluid and diluted faecal matter in the drained screenings are pressed out of the screenings waste. As the compactor screw starts to compact, the clean screenings are discharged into a bin container or plastic bag. On completion of the compaction cycle the system starts from the beginning again.
