Thickening is often the first step in a sludge treatment process. Sludge from primary or secondary clarifiers may be stirred form larger, more rapidly settling aggregates. Function of gravity thickeners are very similar to settling tanks. Solids settle via gravity and compact on the bottom, whereas water flows up over lashers. Gravity thickeners also provide some solids stabilization and storage, which may be beneficial to downstream operations. Smooth up-flow weir design provides uniform distribution of slurry across the entire width of the belt. A large filtration area provides high efficiency thickening and cost-effective chemical utilization.
Services InnovoMAX offers different configurations of gravity thickeners.
