摘要

•A FEEM-PARAFAC model of 7 components was used to track the dynamics of DOM in the UF.•Correlations between water quality and operation were obtained by quantifying fouling.•Microbial by-products and humic-like components showed the highest correlations.•FEEM-PARAFAC did not capture the rejection of biopolymers identified using LC-OCD-OND.
