Understanding the fouling of UF/MF hollow fibres of biologically treated wastewaters using advanced EfOM characterization and statistical tools

► Coupling of EEM and LC-OCD predicts the fouling potential of secondary effluents. ► Identification of the OM characteristics responsible for a high fouling potential. ► Correlation between protein content indicators and a high fouling potential. ► Differentiation of HS from terrestrial origin and HS produced in biological reactors. ► Impact of biological treatment on the EfOM composition by OM characterization.
