Appropriately configured plasma lab-scale reactors to produce discharges above and/or directly inside the pore space of soils. Process optimization and exploration of plasma and pollutant degradation mechanisms.

2. 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, etc.) in aqueous solutions, process optimization and exploration of plasma and pollutant degradation mechanisms. Inactivation of bacteria by cold plasma.

3. Plasma-catalysis: Catalysis-assisted plasma treatment for soil and wastewater remediation.
