Svi30 sludge
WebGranules 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. With the outgrowth of rotifers, granules completely disintegrated in R1 around cycle 500 (a cycle was 3 hours). However, after the rotifers disappeared, i.e. cycle 550, ... 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.
