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.

- Water stream 1 contains around 60,000 ng/l of PFAS in the influent. Short-chain PFAS make up more than 90% of the total PFAS load.
- Water stream 2, with PFAS levels between 20,000 and 25,000 ng/l with almost 70% short-chain PFAS.

**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.
