WebbThe quantity of the return sludge is determined on volumetric basis. The sludge volume index (SVI) is the volume of the sludge in mL for one gram of dry weight of suspended solids (SS), measured after 30 minutes of settling. The SVI varies from 50 to 150 mL/ g of SS. Lower SVI indicates better settling of sludge. Quantity of Return Sludge: Webb2.1.1 CH4 Generation ... 3.2.1 Estimating CH4 and CO2 Emissions from Wastewater and Sludge Treatment ...
