Groundwater treatment plant in Hamme, PFAS removal in groundwater

Published May 22, 2025

The client for this project is Besix Unitec. Besix is currently carrying out work on utility lines in Hamme (Belgium), for which the groundwater level must be temporarily lowered over a distance of approximately 800 metres. The drainage area is located near a fire station, where there is PFAS contamination in the groundwater. In the preparation of the project, it was investigated how the drainage can best take place, and a groundwater purification plant is provided for the execution.

Removing PFAS from drainage water

Verhoeve Belgium takes care of removing the PFAS from the drainage water. To this end, a groundwater treatment plant has been built with a capacity of 50 m3/hour. This installation consists of several buffers, a sand filter, 2 activated carbon filters (connected in series) and a central control cabinet. The total installation can be read out remotely and adjusted if necessary.

Good results

The groundwater treatment plant has been running for some time now and the results are more than satisfactory. The entire plant is expected to be in operation at the site for about 8 months.
