PFAS concentration and removal from landfill leachate is among the hardest challenges in modern water treatment. High organic loads, unpredictable chemistry, and extreme levels of short-chain PFAS often overwhelm conventional methods. But new full-scale data from Chromafora’s SELPAXT installations tells a different story: One of stable, long-term performance in the harshest conditions.
Real-world results, not lab experiments
The data comes from two commercial treatment plants handling active landfill leachate, which is one of the most complex water types in Europe. And these aren’t a pilot or short-term tests. These are full-scale, continuously operated systems that have been running for several months under real operational conditions in existing treatment trains.
One concentration step – scalable if needed
These results are achieved with just one SELPAXT concentration step. For even greater reduction, the system can be configured in two steps – providing flexibility to meet stricter discharge requirements or evolving regulations. While the installations are still relatively new, the SELPAXT process is being continuously optimized and fine-tuned, with the goal of achieving even better performance over time – especially for PFBA and other hard-to-capture short-chain PFAS. The results are already highly promising.
What makes SELPAXT different?
SELPAXT concentration technology combines chemical-enhanced ultrafiltration with a proprietary selective chemistry that targets PFAS molecules, including the ultra-short ones. Unlike many conventional systems, it maintains high performance even in the presence of TOC and other organics, making it ideal for real-world industrial flows like landfill leachate, firefighting training ground runoff and industrial wastewater.
