What is the Sludge Volume Index?
Two 1 L samples of mixed liquor are taken from a lagoon. After settling for 30 min in a graduated cylinder, 250 mL of solids have settled out in the first sample. The total suspended solids concentration (MLSS) in the second sample is found to be 2300 mg/L.
(a) What is the sludge volume index?
(b) What is the theoretical required sludge recycle rate?
Ans:
(a) From eq for SVI, SVI = 1000Vsettled, mL/L/ Xmg/L
= (1000mg/g)(250ml/L)/2300mg/L = 109mL/g
(b) From Eq for, R = Vsettled, mL/L/ 1000-Vsettled, mL/L
250mL / 1000mL - 250mL = 0.33
