Evridiki Barka is a PhD candidate and researcher at the School of Civil Engineering, National Technical University of Athens (NTUA). She holds a Diploma in Civil Engineering and an MSc in Water Resources Science and Technology, both from NTUA. Her research focuses on the removal of organic micropollutants from water and wastewater using physicochemical and biological treatment systems. Her doctoral work explores the application of eco-friendly and innovative materials—such as nano zero-valent iron and biochar—for enhancing organic micropollutants removal efficiency. She has (co)authored six peer-reviewed journal articles and twelve conference papers. She is an active member of the Technical Chamber of Greece and the Association of Civil Engineers of Greece.

Asimina Koukoura is a PhD candidate at the Department of Environment, University of the Aegean. She holds a BSc in Environmental Science from the University of the Aegean and an MSc in Water Resources Science and Technology from the School of Civil Engineering at the National Technical University of Athens. Her research focuses on wastewater treatment technologies, including constructed wetlands and microalgae-based technologies. She specializes in assessing their efficiency in removing conventional pollutants and organic micropollutants, particularly benzotriazoles and benzothiazoles. Additionally, she works on pilot and full-scale technologies aiming at wastewater reuse and the remediation of secondary sludge from persistent and mobile substances.
