Per- and poly-fluoroalkyl substances (PFAS) are a group of manmade chemicals used in various applications, including cookware, firefighting foams, food packaging, and cosmetics. Due to their stability and persistence in the environment, PFAS have been linked to serious health risks such as immune system interference, developmental issues, and certain types of cancer.
As awareness about PFAS grows, regulatory bodies are taking action. In the EU and UK, three toxic PFAS compounds have been banned since 2008, 2020, and 2023. However, end-use restrictions can have long transition periods, and no suitable replacements may be identified in some applications.
To address this issue, Puragen, a leading global supplier of activated carbon filtration systems, has developed a technology that removes and destroys PFAS group chemicals using advanced thermal reactivation. The company’s ‘Search, Capture & Destroy’ approach involves:
1. Advanced analysis techniques to identify specific PFAS compounds
2. Specialised surface-modified GAC to remove PFAS from water
3. Thermal reactivation to completely destroy the PFAS
Puragen’s technology has been shown to increase removal efficiency by up to 200% compared to traditional reagglomerated carbons. The company’s advanced thermal reactivation process, REACT-Sys+, ensures that PFAS levels in air emissions and wastewater streams are at background levels.
Puragen’s solution is circular, recycling spent carbon and destroying PFAS molecules in a three-step treatment process. This approach has been recognised with the prestigious Green Apple Award for Environmental Best Practice, solidifying Puragen’s position as a leader in environmental solutions.
