Removing of per- and polyfluoroalkyl substances (PFAS)
Persistent “forever chemicals” such as PFAS are an urgent global concern - affecting drinking water, industrial effluents, and the environment at large. LANXESS offers a broad portfolio of Lewatit® ion exchange resins to tackle PFAS contamination under diverse conditions.
What are PFAS and why are they a problem?
Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals found in firefighting foams, textile treatments, paper coatings, and lubricants. Their extremely stable carbon-fluorine bonds make them resistant to breakdown - which helps when used in products, but causes major environmental risks once released into water systems.
Key challenges:
PFAS do not degrade in the environment (“forever chemicals”)
They accumulate in living organisms, including humans
Even trace levels must be removed to meet strict global regulatory standards - often in the parts per trillion (ppt) range
How can Lewatit® ion exchange resins help?
LANXESS provides a broad range of Lewatit® ion exchange resins designed to efficiently remove PFAS from both potable water and industrial wastewater. Our solutions have proven effective in meeting the most stringent international requirements.
