Removal of emerging contaminants in sewage water subjected to advanced oxidation with ozone

- Several pharmaceuticals remain in sewage waters after conventional STP treatment.
- Advanced oxidation with ozone is investigated for pharmaceuticals removal.
- The study is made with on pharmaceuticals present in real-world sewage waters.
- Ozone treatment at a dose 7-12 mg/L is proven to be highly efficient.
- The use of ultrasounds did not lead to improved removal efficiencies.
