Demystifying PFAS
What are PFAS?
Per- and poly-fluoroalkyl substances (PFAS) are remarkable yet concerning synthetic chemicals. Prized for their ability to repel stains, water, and oil, these "forever chemicals" boast incredibly strong carbon-fluorine bonds. This durability, while useful in many products, poses significant environmental challenges.
Tasked with remediating PFAS from landfill leachate?
We understand you have questions. Consult with our experts about our PFAS treatment systems today.
Major PFAS Contributors to MSW Landfills
Biodegradable Waste
- Paper products (food-contact materials)
- Food waste (from packaging, processing equipment, water, feed or soil)
- Wood and yard trimmings (coated in PFAS chemicals)
Non-Biodegradable Waste
- Carpets and textiles (stain and water-resistant)
- Non-stick cookware
- Insulation
Biosolids
- Wastewater treatment plant biosolids
- MSW incineration ash (energy recovery)
Industrial Waste
- Metal plating
- Tanneries
- Textile production
PFAS Dynamics in Landfill Environments
PFAS Distribution in Landfills
PFAS concentrations in leachate fluctuate constantly, influenced by diverse waste profiles, decomposition stages, and environmental factors like rainfall. This complex interplay shapes both PFAS levels and overall leachate quality, creating a dynamic chemical landscape within landfills.
The Journey of PFAS in Landfills
In landfills, PFAS undergo continuous transformation and redistribution. They move between liquid (leachate), gaseous (landfill gas), and solid (waste material) phases. Recent research challenges the notion of PFAS immobility, revealing these "forever chemicals" to be more dynamic than previously thought.
Factors Impacting PFAS
Concentrations
Landfill Type —
MSW landfills with liners and leachate collection systems have different PFAS profiles compared to C&D landfills.
Waste Age —
Older waste (10+ years) generally has lower PFAS concentrations.
Leachate pH —
Lower pH levels increase PFAS concentrations.
What is the LEEF System®?
It's a continuous-flow, multi-stage system that removes PFAS from landfill leachate using patented foam fractionation technology.
Why Foam
Fractionation?
Foam fractionation leads the pack in PFAS treatment, outperforming alternatives with its unique blend of efficiency and cost-effectiveness. This innovative method not only excels in removing persistent chemicals but also offers an environmentally friendly solution adaptable to various scenarios.
| Method | Advantages | Disadvantages |
|---|---|---|
| Granular Activated Carbon | Proven, widely used | Not PFAS selective, high costs, high maintenance |
| Ion Exchange | Proven, widely used | Not PFAS selective, high costs, high maintenance |
| Reverse Osmosis | Proven, removes most contaminants | High energy use, large reject stream |
| Foam Fractionation | No pre-treatment, no consumables, low energy, low maintenance |
