AbstractMolecular weight (MW) of organics was one of the important factors influencing membrane fouling propensity. This study identified critical foulants of reverse osmosis (RO) membranes in reclaimed water by MW fractionation. MW > 10 kDa component was identified as the critical fouling contributor (CFC) in secondary effluent (SE), which accounted for only 13 ± 5% of dissolved organic carbon (DOC) but contributed to 86 ± 11% of flux decline.

Water samplesReclaimed water was sampled from a large-scale water reclaimed plant in Beijing, China. A schematic of the advanced treatment process is shown in Supplementary Fig. 10. The effluent from the denitrification filter was chosen as the sample because subsequent treatment units had a bacterial removal effect46. The reclaimed water samples were transported to the laboratory within 1 h, then filtered by filter papers to remove particles, and kept at 4 °C before disinfection.
