To determine the most effective solution, we conducted a site visit and collected water samples from the existing sedimentation tanks in the area. In close collaboration with the customer, we then developed a treatment plant capable of handling both the water already in the tanks and the water that had accumulated on-site.

The delivered treatment solution

The treatment system combines advanced treatment technologies to effectively remove both zinc and PFAS. It includes a collection tank, a flocculation tank with pH adjustment, a sedimentation container, and a series of pressurized activated carbon filters designed specifically to eliminate PFAS11 from the water. The treated water is recirculated through particle filters and BioMedia® filters, further reducing zinc levels and residual floc, while also protecting downstream filtration units.

Flow-proportional sampling ensures efficient process control and minimizes the risk of mishandling treated water. It also enables continuous monitoring to ensure compliance with all environmental regulations. Additional sampling points between filter stages are used to track breakthrough times and optimize performance.

The delivered system is both flexible and robust, with the capacity to be quickly scaled up if required. Testing has confirmed that it effectively treats PFAS, and the setup allows for additional filter units to be added in the future, should new demands arise.

It has been in operation for a few weeks and is already showing promising results. The project will run for at least six months.
