Sludge treatment − gravity thickening - Sludge Processing
2020-6-18 · Gravity thickeners generally retain 80−90% of the solids in the thickened product stream, depending on the sludge characteristics and the efficiency of the preceding conditioning stage. The sludge characteristics also govern the solids loading rate (SLR), which is the rate in kg/d at which the sludge dry solids enter the process per unit process cross-sectional area.
