Using Air Bubbles to Remove PFAS from Landfill Leachate

---

Landfill leachate is a major pathway for PFAS to reach municipal systems and the environment, but many conventional treatment approaches weren’t built to remove these persistent compounds effectively. In an article published by Innovation News Network, we break down where common treatment trains fall short in leachate applications and the science behind how the LEEF System addresses the problem using foam fractionation. 

The piece explains how foam fractionation turns PFAS’s own chemistry against it, using the way these compounds naturally concentrate at air-water interfaces to lift them out of leachate. It also highlights why this approach performs reliably in high-strength leachate, tolerating elevated TDS, resisting fouling, and producing a minimal concentrated waste stream for downstream handling. 

Proven at full scale, the LEEF System helps landfill operators meet evolving regulatory demands while protecting downstream infrastructure and the environment. Read the full article on Innovation News Network for deeper technical detail, performance context, and references.
