- •
MBR fouling differences was due to the variation of gel layer characteristics.
- •
The gel layer resistance increase is the main cause of FRI rising.
- •
Sludge bulking leads to the increase of SVI and small PSD at a low stirring rate.
- •
Sequencing showed that Proteobacteria and Actinobacteria were the dominant phyla.
- •
CFD model can simulate the influence of fluid flow characteristics on MBR fouling.
