Description
This study evaluated the feasibility of using cationic polymers to remove PFAS from landfill leachate through sequestration to suspended solids. Bench-scale testing with three leachate samples revealed that polymers alone were ineffective in raw leachate conditions, primarily due to interference from organic carbon. However, when paired with powdered activated carbon to reduce organic content, modest improvements in PFAS removal were observed. While not viable as a standalone treatment, the research provides critical guidance for future technology development and highlights the importance of upstream organic carbon removal in PFAS pre-treatment strategies.
