"The microbial community in fouling membrane bioreactors: Distribution and diversity of important bacteria"
Membrane bioreactors (MBRs) are promising in wastewater treatment as they meet the challenges of still stricter demands for effluent quality. However, membrane fouling has hampered a wider application of MBRs due to higher operational costs compared to conventional treatment processes.
The aim of this project was to identify and characterize the microbial community in MBRs and understand their effect on sludge characteristics and membrane fouling. Specific bacterial species could be linked to sludge properties influencing the membrane fouling. Filamentous Chloroflexi were associated with poorly flocculated sludge and they dominated the fouling layers in a pilot-scale MBR treating municipal wastewater. The results will provide new approaches for control of membrane fouling.
