Gravity Belt Thickener K-S Gravity Belt Thickener Gravabelt® Gravity Belt Thickeners reduce sludge volume of biosolids and waste activated sludge and produce a pumpable concentrate for dewatering, transport, or further digestion. The K-S Gravabelt® uses only gravity and a porous drainage belt along with our Roto-Kone High Rate Drainage system to enhance thickening performance at a reduced operating cost. The K-S Gravabelt® is specifically designed for continuous operation, high hydraulic throughput, low polymer usage, low maintenance, and long operational life in the highly corrosive environment of waste treatment. A Gravity Belt Thickener employs gravity drainage through a filter belt to thicken polymer conditioned sludge prior to digestion, mechanical dewatering, or trucking to a land application site or disposal site. Dilute sludge (typically 0.5% to 1.0%) is introduced at the feed end of a horizontal filter belt. As the slurry makes its way down the moving belt free water drains through the porous belt. The solids are continuously turned, encouraging the drainage of more water. K-S’s exclusive Roto-Kone® High-Rate Drainage System actually holds back the solids while causing constant movement throughout the entire sludge blanket allowing optimal drainage of free water. Sludge is discharged at the end of the horizontal filter belt as a pumpable thickened sludge.
