Membrane bioreactors (MBRs) are commonly understood as the combination of membrane filtration and biological treatment using activated sludge. Development of a biofilm-MBR has been investigated combining a moving-bed-biofilm reactor with a submerged membrane biomass separation reactor. Treatment eff

Operating the BF-MBR process with low organic loading rates appears to produce a retentate with more favorable characteristics with respect to dewatering, filterability and sludge production compared to high loading rates. Lower membrane fouling rates are also observed, i.e. less frequent cleaning r
