Screw Press

The Q-PRESS® from Huber is a screw press with a conical screw shaft and cylindrical sieves consisting of three treatment zones: inlet and drive zone, three-part thickening and dewatering zone, and press zone with pneumatic counter-pressure cone. The supernatant is quickly removed by the feed pump via a large free filter surface at a low primary pressure while the volume of material between the screw flights is reduced by the conical screw and the sludge is dewatered. Residual water is pressed out of the sludge by the pneumatic counterpressure cone at the press discharge. The sludge residence time in the screw press, and thus the filtration time, can be adjusted to individual requirements by adjusting the rotational speed of the screw shaft.
