AmphoRes™ for PFAS removal
Why choose charge-switching technology for PFAS removal?
Among all available techniques, ion exchange resins are widely regarded as the most efficient solution for PFAS removal, offering excellent performance at a manageable cost. However, traditional ion exchange resins face significant challenges that limit their sustainability and practicality:
- Single-Use Limitation: Conventional resins are typically discarded after saturation with PFAS, requiring frequent replacement with fresh media.
- Environmental Impact of Regeneration: Regeneration often involves washing with organic solvents, leading to environmental concerns and secondary waste streams.
- Disposal Challenges: Disposed media, saturated with PFAS, creates leachate issues in landfills, raising long-term environmental risks.
- Incineration Risks: While incineration is used to reduce landfill waste, it comes with severe drawbacks, including:
- High Greenhouse Gas (GHG) Emissions: Contributing to climate change.
- Formation of Hazardous Byproducts: Producing hydrofluoric acid (HF) due to PFAS contamination in the media.
Ecofilter Tek’s Charge-Switching Technology addresses these challenges with an innovative, regenerable solution that eliminates the need for single-use resins and organic solvents, offering a more sustainable and efficient approach to PFAS removal.
