摘要

This study examined the rejection of twenty-two endocrine disrupting compoundsrn(EDCs) and pharmaceutically active compounds (PhAC) from membrane bioreactorrneffluent and laboratory-grade water (Milli-Q?) by ‘loose’ and ‘tight’ nanofiltration (NF)rnmembranes as well as a reverse osmosis (RO) membrane. Rejection by the ‘tight’ NFrnmembrane was found to be most strongly correlated with individual compound log Kowrnvalues and water solubility, with the more hydrophobic compounds showing higherrnrejection. The RO membrane provided efficient EDC and PhAC removal (>90%).rnConversely, in general, the ‘loose’ NF membrane offered poor and variable compoundrnremoval. Fouling and the presence of organic matter likely contributed to higherrnrejections of EDCs and PhACs by the membranes.
