Screw conveyor / compactor
This equipment is manily dedicated to the treatment of screening waste, sludge and sand/grit as part of the treatment of urban or industrial wastewater.
Shaftless screw conveyor
- The shaftless screw made of special steel is installed in a U-shaped trough, made of successive folded plates of 304L stainless steel in its standard version.
- The absence of a shaft and intermediate stages practically eliminates any risk of clogging.
- Entirely covered, this equipment is secure, odourless and clean. The trough is protected from wear and tear by PEHD or stainless steel lamellas.
- In each case, the gear motor can either push or pull. The screw conveyor can be installed both indoors and out and has a large number of discharge options.

Shaftless screw compactor
This system compacts the screening waste from sewage treatment plants. The volume reduction can reach 50%, and dryness: 30%.
The screw compactor includes a drainage area, a transport area and finally a dewatering/compacting area
- The waste is transported to the compacting area by a stainless steel shaftless screw. The press housing, the wringing unit and the conveyor tubes are made of 304L stainless steel in the standard version
- The trough is protected from wear and tear by PEHD or stainless steel strips
- The waste is dewatered according to the length of the plug and the pressure exerted by the adjustable outlet valve, by means of a counterweight. The expressed liquor is evacuated via a drain
In order to avoid stagnation of the liquors in the screw trough, the screw should be installed at a slight slope(2 or 3°)
- The longest possible trough is 6 linear metres for a slope of 20°
- R&O also offers a bagging system. The plastic bags are 90 m-long endless bags or filter bags.
