WebbThickening is defined as removal of water from sludge to achieve a reduction in moisture content of slurries. The resulting material is still fluid. Thickening is used at most wastewater treatment plants, as an economic measure, to reduce the volume of sludge or for greater efficiency in subsequent processes. WebbSoftener sludge is rarely thickened because it concentrates well in the clarifiers. If necessary it can be further thickened to 20−30%wwor more at a dry solids loading rate of about 8 kg/h.m2. To prevent the softener sludge becoming too thick underflow is sometimes recycled to the feed.
