Webb5 sep. 2016 · This is our formula: Sludge age in days = MLSS pounds in aeration / MLSS pounds added to aeration. You see, we have neither of those numbers specifically given to us in the data in the … Webb9 apr. 2014 · It was reported that typical biofilm concentration ranges from 3,000 to 4,000 g TSS m −3 which is similar to values obtained in activated sludge processes with high sludge ages because of which the volumetric removal rate in the MBBR is several times higher than that in the activated sludge process (Ødegaard et al. 1994 ).
