Sludge thickening in wastewater treatment

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. 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.
