Abstract


  • This study examined the relationship between molecular properties and the fate of trace organic contaminants

    (TrOCs) in the aqueous and solid phases during wastewater treatment by MBR. A set of 29 TrOCs

    was selected to represent pharmaceuticals, steroid hormones, phytoestrogens, UV-filters and pesticides

    that occur ubiquitously in municipal wastewater. Both adsorption and biodegradation/transformation

    were found responsible for the removal of TrOCs by MBR treatment. A connection between biodegradation

    and molecular structure could be observed while adsorption was the dominant removal mechanism

    for the hydrophobic (logD > 3.2) compounds. Highly hydrophobic (logD > 3.2) but readily biodegradable

    compounds did not accumulate in sludge. In contrast, recalcitrant compounds with a moderate hydrophobicity,

    such as carbamazepine, accumulated significantly in the solid phase. The results provide a

    framework to predict the removal and fate of TrOCs by MBR treatment.
