SLUDGE VOLUME INDEX – SVI<\/strong><\/span><\/h2>Sludge Volume Index, also known as SVI, describes how well the sludge from the aeration tank settles and compacts.

The first number comes from a 30-minute settleability test, where 1 liter of the mixed liquor sample from the aeration tank is poured into a container called a settleometer. The sludge is allowed to settle for 30 minutes, and the volume of the settled sludge is measured in mL\/L.<\/span><\/p>The other number used in the sludge volume index ( SVI ) calculation comes from a MLSS test.
