Svi30/svi5

WebTwo sequence batch reactors (SBRs) with airflow rates of 4 (R1) and 6 (R2) 1 min(-1), respectively, were used to develop aerobic granules. Granules were well developed with excellent settleability in terms of SVI30 (sludge volume index,) of about 50 ml g(-1) in both reactors at the beginning. WebIn this study, a dense and stable aerobic granular sludge with excellent settling properties (with sludge volume index after 5 min of settling (SVI5) decreased to 19.46 mL/g and SVI30/SVI5=1) and diameter size of approximately 10 mm was successfully cultivated in a sequencing batch reactor system fed with synthetic tomato paste to process wastewater.
