|a Microbial indexes of filamentous bacterial density were evaluated for their potential to act as indicators of sludge settling characteristics for sequencing batch reactor (SBR) and membrane bioreactor (MBR) treatment options. These options were operated using settled sewage over a range of aerated loading rates from 0.05 to 0.4/d and the evolution of protozoan and metazoan populations analysed. A filament density score ranging between 0 and 5, which has previously been applied to conventional activated sludge processes, was shown also to be a useful tool for the SBR and MBR, and was correlated to the settleability of the mixed liquor from both reactors. Due to the hydrodynamics of both systems and the subsequent differences in mixed liquors, optimum performance for each bioreactor was obtained under different operating conditions. Although there was no correlation between the numbers of any given protozoan species and plant operating conditions, there was a clear dependence between operating conditions and protozoan diversity. The highest diversity was found when operating conditions were optimum for both the SBR and MBR
