In a CASS-process municipal wastewater treatment plant, SV30 values are high and many rotifers can be seen under microscopic examination; the MLSS level is 2800. I seek advice from those with more experience.

Sludge aging is likely to occur due to excessive aeration or too low F/M.

Is there scum on the aeration tank, or on the measuring cylinder after sampling? If it’s the latter, the denitrification-generated gas rises to the surface; stirring it causes it to sink back down

Is sludge discharge normal? Besides overexposure, it may also be related to sludge discharge.
