WebbTreatment of sewage sludge may include a combination of thickening, digestion, and dewatering processes. Thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. Thickening is usually accomplished in a tank called a gravity thickener. WebbSludge Dewatering Benefits Waste Volume Reduction Because sludge dewatering focuses on weight and volume reduction to minimize waste disposal costs, as the name of the method implies, water removal is the principal means to reduce volume before the sludge by-product can be economically disposed of.
