Emerging micropollutants such as endocrine disrupting chemicals (EDCs) and perfluorinated compounds(PFCs) have added water quality observation item for the purpose of strengthening domestic qualitystandards for drinking water. In drinking water treatment system, the unit operations in advanced watertreatment (pre and post ozonization, chlorine oxidation) and changes of water quality parameters(temperature, pH and DOC) effect on the removal efficiency of the emerging micropollutants. Therefore,onsite removal prediction and immediate response have become challenges when micropollutants are foundfrom raw water. In this study, chemical and physical properties of 144 of micropollutants were analyzed todraw optimal removal efficiency of advanced water treatment process such as activated carbon, ozonization,and NF/RO membrane. The activated carbon system will be effective for removal endocrine disruptingchemicals and residual pharmaceutical compounds which are highly volatile and hydrophobic with overLogKow 4. In case of NF/RO membrane is concerned to one of the optimal removal process for the someof persistent organic pollutants which have higher molecular weight and low pKa under 2.5. In accordancewith these aspects, design improvement and research of advanced water treatment of will required forincrease the efficiency of micropollutants control.
