摘要： Provided is a solid-liquid-separation processing method in which solids in a slurry are separated and removed by applying multistage washing to the slurry, in which, even in the case where the number of connected thickening-apparatus stages is smaller, the clarity of obtained supernatant liquid can be improved. In the solid-liquid-separation processing method in which thickening apparatuses each equipped with an agitation tank and a sedimentation tank having an overflow unit in a peripheral portion thereof to discharge supernatant liquid and a cylindrical feed well vertically arranged at a central portion thereof are provided in multiple stages, and multistage washing is applied to a slurry to separate solids in the slurry therefrom and obtain a solution from which the solids are removed, when a flocculant configured to flocculate the solids in the slurry is added, a predetermined proportion of the flocculant is added to a feed well in a first-stage thickening apparatus, and the remainder of the flocculant is added to an overflow unit in a second-stage thickening apparatus.

摘要： A system for sludge removal in a circular settling tank having a side wall (106) comprises a rotatable drive ring (130) adapted to be interconnected to a scraper arm provided with scraper blades, wherein the drive ring having a plurality of engagement surfaces (134) A traction assembly (140) is fixedly attached to the side wall and comprises a drive wheel (142). By providing a drive wheel with a plurality of engagement rolls (148) adapted to engage the engagement surfaces of the drive ring during rotation of the drive wheel, the drive ring can be rotated essentially without exerting any radial forces on the drive ring.
