Web7 Feb 2024 · Sludge thickening precedes sludge digestion and stabilization, and reduces the free water content in the sludge, leaving a biosolids content of between 5% and 10%. This initial reduction in water volume allows for a smaller and more cost-effective sludge digester. Common methods of sludge thickening include disc thickeners, screw … WebSludge thickening. Even though most water is separated at the beginning of wastewater treatment, raw sludge is still physically very liquid. Sludge thickening is a low-energy step that separates more water from the solid components before anaerobic digestion. It reduces the overall sludge volume and increases the proportion of solids in the sludge.
