WebbCalculating the Daily Sludge Production of an Sewer Wastewater Treatment Plant. Below you can find the typical formulas, coefficients and empirical data used to establish the basic design of a complete mix suspended growth biological sewage wastewater process. 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:
