The historical contamination at the former paper mill in Willebroek involves high concentrations of PFAS. The site has been redeveloped into a residential area, and to ensure that both the new residents and the surrounding area are adequately protected from these harmful substances, we are deploying new techniques. Following successful laboratory tests and a pilot project, we are now rolling out this innovation on a large scale.
We are combining our soil-flush technique with on-site water treatment. By pumping water into the soil, the PFAS are dislodged. Using a recirculation system, we pump the water, together with the PFAS, back up to the surface. To purify the water, we skim the PFAS off the surface in the water treatment process, thereby separating them from the water. We then subject the water to an additional filtration stage before it is returned to the soil for the next cycle.
This way, we avoid having to excavate contaminated soil around buildings whilst simultaneously minimising the plant’s water consumption. Another advantage is the minimal disruption to local residents. And because the highest concentration of PFAS contamination is found at a depth of just a few metres, this combination of techniques is also the most suitable solution for this site.
On this project, we are collaborating with OVAM, the Flemish Environment Agency, the Institute for Nature and Forest Research, KU Leuven, the University of Antwerp, the Province of Antwerp, VITO, Bio2Clean, TAUW and Novobiom.
In addition to remediation techniques, LIFE PFASTER also focuses on how PFAS spread and behave in soil, water and the natural environment. We aim to use this knowledge to tackle PFAS contamination in a systematic and area-specific manner. The project receives financial support from the EU.
