It is defined as "the volume in ml occupied by 1 g activated sludge after settling the aerated liquor for 30 min" (2). The sludge density index, introduced by Donaldson (3), is the reciprocal of the SVI multiplied by 100. Both of these indices originally were intended to be rough measures of sludge settle ability to be used ...
