Sludge thickener design calculations
WebbSoftener sludge is rarely thickened because it concentrates well in the clarifiers. If necessary, it can be further thickened to 20–30% w/w or more at a dry solids loading rate of about 8 kg/h.m 2. To prevent the softener sludge becoming too thick, underflow is sometimes recycled to the feed. WebbOn the surface of the unit, a sludge float blanket will be maintained anywhere from 8 to 24 inches in thickness. The primary variables for flotation thickening are: Pressure Recycle ratio Feed solids concentration Detention period Air-to-solids ratio Type and quality of sludge Solids and hydraulic loading rates Use of chemical aids
