Wastewater treatment by non-thermal plasma
Lab-scale studies of several plasma configurations (gas-liquid DBD and corona, plasma bubbles) for the degradation of various organic pollutants (e.g. PFAS, antibiotics, dyes) in aqueous solutions. Inactivation of bacteria by cold plasma. Process optimization and exploration of plasma and pollutant degradation mechanisms.
