Web29 ago 2024 · The sludge blanket, SVI, and TSS all dropped by 86% to 97%, while producing high effluent quality. Figures 11 – 15 demonstrate the diverse microbial communities harvested from the Moorefield WWTP, using fluorescent in situ hybridization (FISH) technique and fluorescent microscopy. Web1 dic 1997 · AGS rapidly formed in terms of sludge volume index (SVI) and AGS fraction and stabilized (SVI30: 62 ± 5 mL g −1, AGS fraction: 40–60 %). The installation of a novel SBR cycle, with alternately repeated steps of short and long aeration times, further improved the settleability (SVI30: 47 ± 6 mL g −1 ) and contributed to an increase in AGS …
Sludge volume index - Wikipedia
WebAerobic granular sludge was successfully Low organic content has been proven to produce smaller developed with low sludge volume index (SVI30) of 29 mL/g, which granules with loose and porous structure [5]. demonstrated an excellent settling property of aerobic granular First attempt of aerobic granulation using domestic sludge. WebThe SVI30 reduced to 121 from 231 mL/g. The reduction in Sludge Volume Index30 (54%) showed the effectiveness of the treatment after 10 days. The higher Total Suspended Solids (TSS) concentration may be due to the suspension in the mesh or nest-like filamentous structure, reducing the amount of solids to settle down at the base of the clarifier. leg length traduction
