Background
The waste management plant suffered from very high levels (90-95%) of short-chain PFAS in the landfill leachate. The customer spent two years searching for a solution to remove PFAS without any real success, screening 30+ suppliers and testing 10 methods – before evaluating SELPAXT.
Process
After evaluation and discussions with the customer, these are the steps we took together to reach full scale operation:
- Lab scale verification Dec 2021
- On-site verification September 2022
- Full-scale installation September 2023
- Installation scope: Pre-treatment, SELPAXT treatment, post-treatment, including full service operational commitment
- Treatment volume: 30,000 cubic meters per year
Results
- Successful full-scale installation operating since September 14, 2023
- Site analyses confirm treatment results from on-site verification – reducing more than 90% of short PFAS chains
