Cover Story: A promising solution for membrane fouling reduction in membrane bioreactors (MBRs) could be the adjustment of operating parameters, such as hydraulic retention time (HRT), food/microorganisms (F/M) loading, and dissolved oxygen (DO) concentration, aiming to modify the sludge morphology to the direction of improvement of the membrane filtration. In this work, these parameters were investigated in a step-aerating pilot MBR, in order to control the filamentous population. When F/M loading in the first aeration tank was ≤0.65 ± 0.2 g COD/g MLSS/d, DO = 2.5 ± 0.1 mg/L and HRT = 1.6 h, the filamentous bacteria were controlled effectively at a moderate filament index, leading to low transmembrane pressure for a great period and, therefore, improving the membrane performance.
