Abstract/Summary In countries with irregular and unreliable rainfall, such as Australia, recycling of secondary wastewater effluent using advanced water treatment processes is increasing. Many emerging contaminants are not properly removed by conventional wastewater treatment processes and are expected to be persistent in the effluent. The presence of dissolved organic matter (DOM) can influence the transport, degradation and removal of emerging contaminants. However, very little is known regarding the fate of micropollutants in the presence of DOM from wastewater treatment. Further, the quality and quantity of DOM is modified during the advanced water treatment train and this can also influence the interaction with contaminants. The aim of this study was to determine DOM-water partition coefficients (KDOM) for selected emerging contaminants with DOM isolated at various steps of the treatment train. The studied contaminants included nonylphenol, carbamazepine, diuron and triclosan. Using a novel methodology, KDOM was determined using preloaded polydimethylsiloxane (PDMS) disks to measure contaminant depletion to DOM. Further, the DOM was characterised throughout the treatment chain to understand how the changing properties influence KDOM. This study demonstrated the importance of DOM properties for micropollutant partitioning and has implications for improved micropollutant removal during advanced water treatment processes.
