Pharmaceuticals and PFASs (perfluoroalkyl substances) presented in water environment have gained immersing attention due to their potential harmfulness to human and ecosystem. In this study, the removal efficiencies of several representative pharmaceuticals and PFASs by various advanced drinking water treatment processes (ozonation, GAC adsorption, and RO process) were investigated. It was found that chemically-robust PFASs were hardly removed by ozonation, whereas GAC and RO processes showed relatively higher removal efficiency. Among the pharmaceuticals, carbamazepine, crotamiton and sulfamethoxazole were effectively removed by all the above processes, however, metformin showed relatively low removal efficiency due to its chemical stability and high hydrophilicity. |
