文摘
- •
EEM–PARAFAC was successfully applied to track fluorescent DOM in MBRs.
- •
Tryptophan-like component can be used as the surrogate of EPS production in sludge.
- •
Tyrosine-like component is closely related to the stability of sludge.
- •
Tryptophan-like component is transformed to microbial humic-like component.
- •
Protein-like components are mostly responsible for membrane fouling in MBRs.
