Mellifiq Awarded Long-Term Contract for PFAS Removal from Leachate Water

Mellifiq has been awarded a long-term contract to treat PFAS residues in leachate water collected in a pond in central Sweden. The project is particularly challenging due to the high variability of contaminants and suspended solids, demanding environmental conditions, and the remote location of the site.

The delivery comprises a multi-stage treatment system with flocculation, filtration, and ion exchange, together with integrated automation and service. The system is designed to treat up to 10 m³/h and to reduce PFAS11 compounds by more than 90%.

To secure uptime throughout all four seasons, the systems will be delivered in insulated, air-conditioned containers. Mellifiq’s dedicated service organization will manage the operational aspects of the plant, including sludge management, performance monitoring, and laboratory analyses, ensuring that effluent limits are consistently met.
