High-pressure membrane separation processes including reverse osmosis (RO) and nanofiltration (NF) have been widely used for drinking water purification and water recycling as well as for the removal of trace organic contaminants (TrOCs). Rejection of TrOCs by NF/RO membranes is governed mainly by size exclusion, electrostatic repulsion and hydrophobic interaction. A detailed characterisation of the membrane and physicochemical properties of the TrOC is key to recognising the dominant mechanism. TrOC rejection by NF/RO membranes can also be influenced by fouling and subsequent chemical cleaning. It is, therefore, essential to understand the transport of TrOCs through NF/RO membranes in order to ensure adequate treatment and at the same time avoid over-engineering. In addition to NF/RO, TrOCs removal by several emerging membrane technologies, including forward osmosis, membrane distillation and membrane electrodialysis, is reviewed briefly.
