Sludge thickening process

Webb3 mars 2024 · To make treatment and processing easier, sludge is typically thickened in a dissolved-air flotation tank or gravity thickener. A dissolved-air flotation tank thickens the sludge by using air bubbles to carry the solids to the surface, forming a layer of thickened sludge on the top. WebbThe most common conventional processes include sludge thickening, dewatering, and drying. Figure 9.1 presents the sludge solid content (% of dry mass) during the sludge dewatering processes. After thickening, the sludge mass is usually reduced up to 70% of the initial value, due to water loss, and the solid content reaches 2-3%.
