WebThickening is the first step for reducing the sludge volume by removal of free sludge water. Thin sludge is concentrated to thick sludge. Thick sludge has a higher viscosity, but must still be pumpable. Sludge settles in gravity thickeners and is compressed by the weight of its own solids. Due to their higher specific density, primary and ... WebEven small amounts of entangled material will render sludge inhomogeneous, increase the required drive power and have a negative effect on drainage and mechanical thickening. Contact-based macerators like the RotaCut are self-sharpening grinders, which even cut fibers and hairs, thereby macerating them.
