WebbThickening is the first step for reducing the sludge volume by removal of free sludge water. Thin sludge is concentrated to thick sludge. Thick sludge has a higher viscosity, but must still be pumpable. Sludge settles in gravity thickeners … WebbTreatment of sewage sludge may include a combination of thickening, digestion, and dewatering processes.
