PFAS is a man-made chemical that helps make pans non-stick, firefighter’s foam extinguish, and textiles waterproof. PFAS’ carbon-fluorine bond is one of the strongest chemical bonds known, which can become a problem, resisting breakdown such that they accumulate in the environment as dangerous “forever chemicals” and leach into our communities – from landfills for example. PFAS is found in up to 45% of US drinking water and is toxic and harmful to humans and the environment.
Allonnia is on a mission to remove PFAS from contaminated water across a wide range of site conditions. We deploy a naturally elegant solution called SAFF®, Surface Active Foam Fractionation. Manufactured by EPOC Enviro, SAFF is a precisely engineered, patent-pending system that separates PFAS molecules from contaminated water sources, transforming them into a destruction-ready, hyper-concentrate using just air.
Versus alternative removal techniques that employ mechanical or chemical means, SAFF capitalizes on a natural physicochemical trait to separate and concentrate PFAS. The molecules are simultaneously hydrophilic and hydrophobic, naturally adhering to a gas/liquid interface, and so they are especially attracted to the surface of air bubbles. SAFF generates millions of rising air bubbles that attract the PFAS compounds and separate them from the contaminated water that is pumped through a network of highly specialized fractionation tanks inside a purpose-built transportable container.
SAFF’s completely natural process provides numerous operating advantages:
To date, Allonnia has successfully deployed and helps operate SAFF units across more than a dozen sites from California to Massachusetts.
