%X This paper studied membrane organic fouling during the microfiltration with secondary effluent organic matter (EfOM). Effects of pre-ozonation on the characteristics of EfOM and on EfOM membrane fouling were also investigated. The results show that hydrophilic substances (HIS) have a higher fouling potential due to a higher content of macromolecular and carboxylic groups and also higher soluble microbial products (SMP) or SMP-like substances. Pre-ozonation of EfOM increased the amount of carboxylic and phenolic groups, which could have aggravated membrane fouling. However, the reduction of dissolved organic carbon (DOC) (including the mineralization of small organic molecules) and the breakage of large molecules were suggested to be the major criteria for fouling reduction.
