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:
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
Expandable controls to link to external tanks, conveyers, waste bulkers technologies
Only two consumable parts – typical 10,000 hours ring lifespan and 30,000 hours screw lifespan (3/9 years if run at 9 hours per day)
Adjustable CIP systems to auto- clean between batches or low levels
Self-cleaning filter enables stable and constant dewatering without depending on high amounts of water consumption to prevent clogging
Chemical regime optimised for use with our technologies
Low maintenance and operator interaction with automatic stop/start
Siemens HMI control panel can link to existing SCADA systems
Throughput can be increased by adding a cylinder unit if extendable base is chosen
All-in-one design and easy to install
Container and skid mounted options for temporary solutions – hire and trial
Specialist in wastewater and trade effluent solutions to help bring your site into consent.
The dewatering cylinder comprises alternating fixed rings, moving rings and spacers enclosing a conical screw tapering towards an end plate.
The rings move continuously to clean the sludge between the gaps and prevent clogging.
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.
