To reduce the release of pharmaceuticals and endocrine disruptors into the aquatic environment or to remove them from wastewater intended for direct or indirect reuse, the application of advanced wastewater treatment may be required. In the present study, municipal wastewater effluents were treated with ozone (O3) in a pilot-scale plant consisting of two bubble columns. The investigated effluents, which varied in suspended solids concentrations, comprised an effluent of conventional activated sludge treatment (CAS), the same effluent dosed with 15 mg of TSS L(-1) of activated sludge (CAS + SS), and the effluent of a membrane bioreactor pilot plant (MBR). Selected classes of pharmaceuticals were spiked in the wastewater at realistic levels ranging from 0.5 to 5 microg L(-1). Samples taken at the inlet and the outlet of the pilot plant were analyzed with liquid chromatography (LC)-electrospray tandem mass spectrometry (MS). Macrolide and sulfonamide antibiotics, estrogens, and the acidic pharmaceuticals diclofenac, naproxen, and indomethacin were oxidized by more than 90-99% for O3 doses > or = 2 mg L(-1) in all effluents. X-ray contrast media and a few acidic pharmaceuticals were only partly oxidized, but no significant differences were observed among the three effluents. These results show that many pharmaceuticals present in wastewater can be efficiently oxidized with O3 and that suspended solids have only a minor influence on the oxidation efficiency of nonsorbing micropollutants.

- Urban wastewater treatment plants as hotspots for the release of antibiotics in the environment: a review. (2013, methodology): “Clindamycin was already removed by 95% with an ozone dose of 2 mg L 1 (0.40 g O3 g 1 DOC) (Hollender et al., 2009) and tetracycline by 100% with an ozone dose of 1.5 mg L 1 (Huber et al., 2005).”
- Removal of residual pharmaceuticals from aqueous systems by advanced oxidation processes. (2009, background): “Kulik et al. (2008) reported that effluents from ointment manufacturing that had partly been pre-treated by an adsorption/flocculation/filtration process could subsequently be subject to Fenton oxidation/lime coagulation, thus yielding a final effluent suitable for disposal.”
- Treatment of micropollutants in municipal wastewater: ozone or powdered activated carbon? (2013, background): “The lower ozone reactivity of the metabolites can be explained by the protective effect of the hydroxyl or acetyl group on the reactive moiety, which changes the electron density and thus slows down the reaction (Huber et al., 2005).”
