This study examined the occurrence and removals of 14 micropollutants in the influents and the treated effluent of each process in a WTP. 12 out of the 14 micropollutants were detected in the influent source waters and 11 compounds survived in the final effluent at ppt level. MPT showed the highest level in both the influent and effluent. There was a seasonal variation in the micropollutant level. Most of the removals of micropollutants occurred at the coagulation stage in the WTP. Our results indicate that the removal of micropollutants during lab scale experiment and at the WTP can be somewhat different, and the physicochemical properties are important parameters in the removal of micropollutants during the WTP.
