Abstract: Two membrane bioreactors (MBRs; volume = 300 L) equipped with different types of immersed membrane modules were operated simultaneously
under the same laboratory conditions as a low-loaded activated sludge process without any membrane regeneration and excess
sludge uptake (sludge retention time SRT up to 170 d; activated sludge concentration MLSS up to 11 g L−1). The aim was to verify the quality of treated water and to study the properties of "very old" activated sludge. Another
aim was to compare different selected membrane types and choose the best one for further pilot-scale testing.
Keywords: activated sludge activity - biomass growth - sludge retention time - membrane bioreactor - membrane fouling - sludge settling ability
