How to Calculate and Control Sludge Volume Index (SVI)

Webb25 juni 2024 · If the SVI is 80 mL/g or less, the sludge will be very dense and will settle rapidly. If the SVI is between 100 and 200 mL/g, the sludge will settle a little more slowly, trapping more particulate matter during the settling process. If the SVI is above 250 ml/g, the sludge is very, very slow to settle, and does not compact well.
