The main objective of WP7-Technical Solutions is to advance next generation removal options for prioritized persistent and mobile substances in water and sludge.
This will be achieved by the following sub-objectives:
▼ To innovative analytical methods for monitoring persistent and mobile substances.
▼ To demonstrate and evaluate the removal of persistent and mobile pollution by new technical remediation solutions
▼ To characterize the fate of persistent and mobile substances during waste water sludge treatment
Technological advances are needed to be able to remove more persistent and mobile substances from water and sludge. However, the choice of method should also be based on an evaluation of technical and economic costs and benefits, as well as net environmental effect. Ideally, persistent and mobile substances will be removed sustainably before emissions are widespread or they reach drinking water. By considering the environmental, economic and social costs and benefits of next generation removal technologies for persistent and mobile substances, the limit of sustainable removal will be found. To prevent regrettable remediation, environmental and cost efficiency of removal options of persistent and mobile substances will be studied.
Case study areas for this work include the “Rastatt case” in Germany, the Upper Rhine area of German, as well as Mytilene on the island of Lesvos, Greece.
WP7 will be led by Dr. Marcel Riegel (TZW). Within this WP, members from NIVA including Dr. Ian Allen, Dr. Bart van Bavel, Dr. Laura Röhler and Dr. Thomas Rundberget will be leading the target and non-target PFAS + PMT/vPvM analysis methods for water and treatment byproducts. The success of water treatment using various technologies will be led by TZW, with members including Dr. Frank Thomas Lange, Heico Schell, Dr. Karsten Nödler, Michael Merklinger, Lukas Lesmeister. Dr. Marco Scheurer also contributed to this work early in the planning stages. The University of the Aegean will be looking at the fate and production of PFAS and PMT/vPvM substances by sludge treatment methods, with members including Dr. Nasos Stasinakis, Dr. Michalis Fountoulakis, Dr. Stergios Vakalis, Dr. Olga-Ioanna Kalantzi and Dr. Georgia Gatidou. Complimenting this work is the involvement of Chalmers University, members Dr. Greg Peters, Dr. Rikard Arvidsson, Dr. Magdalena Svanström and Dr. Sverker Molander, who will be assessing life cycle effects of this treatment, in addition to other aspects of the chemical life cycle, of prioritized PM substances.
