Settleability Volume Index
Sludge Volume Index (SVI) is a process control parameter used to describe the settling characteristics of sludge in the aeration tank of an activated sludge process. It was introduced by Mohlman in 1934 and has become one of the standard measures of the physical characteristics of activated sludge processes. The SVI is often used to assess if process performance issues are related to the proliferation of problematic filamentous organisms that cause poor settling in secondary clarification processes. It is defined as 'the volume (in mL) occupied by 1 gram of activated sludge after settling the aerated liquid for 30 minutes'{{cite web, title=SLUDGE VOLUME INDEX (SVI), url=http://www.aquanova.cz/sludge_volume_index.htm, accessdate=19 November 2016 and can be calculated as follows: ::SVI (mL/g) = settled sludge volume (mL/L)/mixed liquor suspended solids(MLSS)(mg/L) * 1000 (mg/g) The sludge is often too thick and has to be diluted with clarified secondary effluent before analyzing th ...
