Volute FS Screw Press
Proven performance for standard sludge applications
The Volute FS screw press range offers sludge thickening and dewatering of dissolved air floatation (DAF) and biological (aerobic and anaerobic) sludge and raw effluent flows.
The FS screw press has an automatic self-cleaning filter that prevents clogging and enables constant dewatering without using large volumes of water.
It is suitable for:
- Primary sludge such as DAF
- Secondary treatment sludges such as activated sludge
- Aerobic and anaerobic bio solids
- Digestate dewatering
- Fibrous sludges
- Oily sludges
A wide range of applications across a variety of industries
Industrial wastewater and trade effluent
Utilities and municipal wastewater
Hire, trial or capital purchase
What are the highlights of our Volute FS Screw Press?
Dewatering with a screw press solution offers industrial clients a low-energy, low-maintenance way to cut their carbon footprint and join the circular economy. It cuts out the need to transport large volumes of unprocessed waste. It can save money and create new revenue streams with a portable and ready-to-use product for growing markets.
- 70% footprint space saving compared to standard screw press
- Up to 99% saving on cleaning water against belt press, and 92% against conventional screw press
- No thickening or storage tanks needed
- Only 5% of the power usage of a comparable centrifuge
- Sensor-controlled operation – automatically run for 24-hours
- Noise minimised due to non-rotating body at high speeds

How the process works
Step one
The dewatering cylinder comprises alternating fixed rings, moving rings and spacers enclosing a conical screw tapering towards an end plate.
Step two
The rings move continuously to clean the sludge between the gaps and prevent clogging.
Step three
The first part of the screw section is called the Thickening Zone, thereafter, the pitch of the screw narrows with the gaps between the rings and the screw pitch decreasing towards the end plate.
