The HUBER Q-PRESS® RoS3Q Inclined Sludge Press is a unique sludge dewatering machine developed by HUBER over 20 years ago and now over 1200 machines have been installed globally in many applications.

Now with the release of the next generation HUBER Q-PRESS® the RoS3Q has just become even more efficient and can be operated at even higher solids throughputs.

In addition as an option the HUBER Q-PRESS can be supplied with axially divided basket segments which allows for most maintenance to be completed without removing the screw shaft.

One of the key features of the screw press is its slow operational speed. The basket and screw rotates at <1.5rpm thus minimising wear and prolonging life and service intervals.

Several HUBER Q-PRESS® models are available with capacities ranging from 20 to 540Kg DS per hour to suit all municipal and industrial applications for dewatering of primary or secondary sludge.

All machines are fully enclosed and manufactured in stainless steel.

Sludge is firstly flocculated in-line with a polyelectrolyte and enters the machine.

The machine consists of a main case, internal screw rotating at <1.5rpm), spray bar and cylindrical wedgewire/mesh drum. As the sludge enters the unit the sludge is conveyed by the screw through the drum length whilst the filtrate is drained through the mesh. The drum consists of variable apertures and profiles, and together with a reducing screw pitch and increased shaft diameter, pressure is gradually applied to the sludge mass.

The ultimate high pressure zone is at the outlet section where an adjustable pneumatic cone is configured to achieve maximum sludge dryness. The cake is discharged through the cone into a bin or conveyor systems and the filtrate collects within the main case and is discharged via gravity to the filtrate outlet flange.
