WebbSludge Volume Index. The sludge volume index (SVI) is another key parameter and used to describe the settling characteristics of the sludge. The SVI is expressed as the volume occupied by 1 g of sludge (mL/g) after 30 min of settling time. Well- settled sludge normally yields a clear separation between the water and the sludge. WebbHighly effective methods of biological and chemical treatment aimed at increasing the removal of biogens and reducing organic matter generate significant amounts of sewage sludge (at an estimated amount of 2841.739 thousand tons in the European Union in 2024), which require management [ 3 ].
