Sludge Treatment in Wastewater: Enhancing Efficiency and …
Wastewater systems rely on several methods to remove sludge, including gravity sedimentation, flotation, centrifugation, and filtration. These processes separate solids from the water, enabling further treatment or disposal of the sludge.
Sludge, or residual solids, is the end product of wastewater treatment, whether biological or physical/chemical treatment. Primary sludge is from 3 to 6 percent solids. Treatment objectives are reduction of the sludge and volume, rendering it suitable for ultimate disposal.
At municipal wastewater treatment plants in the United States, raw municipal wastewater undergoes preliminary, primary, secondary, and in some cases, additional treatment to yield treated effluent and a concentrated stream of solids in liquid, called sludge.
