Understanding SVI, MLSS and Why These Parameters Matter

Sludge Volume Index (SVI) is a key measurement used in wastewater treatment to assess how well sludge settles in the aeration tank. It informs operators how much space one gram of sludge occupies after 30 minutes, providing a clear indication of whether the sludge is settling properly. A high SVI can signal issues such as filamentous bulking, which can impact clarifier performance and result in poor effluent quality. Monitoring SVI regularly helps plant teams make better process decisions and avoid costly compliance problems.

The S3A also measures other critical parameters like MLSS (Mixed Liquor Suspended Solids), SSL (Settled Sludge Level), supernatant clarity, and floating sludge detection. MLSS indicates the amount of suspended solid material present in the biological treatment stage — too much or too little can impact treatment performance. SSL indicates how far the sludge has settled, and supernatant clarity indicates the cleanliness of the water above the sludge. Floating sludge detection alerts operators to potential process issues, such as denitrification or poor floc structure. Together, these measurements provide a complete picture of sludge behaviour and help operators optimise treatment performance.
