Contaminants in wastewater treatment

Micropollutants from urban sources (e.g. pharmaceuticals, personal care products, industrial chemicals) enter the aquatic environment via municipal wastewater. We are investigating their mass fluxes from the usage, their behavior during wastewater treatment and their environmental fate in the water cycle. We are mainly interested in the wastewater treatment processes and in strategies, how to remove these organic micropollutants in conventional and advanced treatment with ozone and activated carbon.

Current projects

Treatment with powdered activated carbon (PAC) and ozonation are established methods for advanced wastewater treatment plants...
Ozonation is one of the treatments used in wastewater treatment plants (WWTPs) to remove MPs, reducing their discharge to the aquatic environment...

Terminated projects
