PFAS Annihilator™ Destruction Technology
Don’t Move PFAS. Destroy It.
How It Works
A supercritical fluid is a substance held at a temperature and pressure above its critical point. In this state, the fluid is neither a liquid nor a gas and has properties of both. Substances begin to act differently above the critical point. Supercritical water is highly expandable and compressible. Without distinct liquid and gas phases, mass transfer is unrestricted, facilitating chemical reactions. Supercritical oxidation processes can rapidly break down compounds, such as PFAS, that do not oxidize readily at standard temperatures and pressures, destroying chemicals that would otherwise persist for decades or centuries in the environment.
Significant Success in Breaking Down the Unbreakable
In bench-scale trials of more than 30 PFAS-contaminated sample types, PFAS Annihilator consistently demonstrated more than 99.99% destruction of total PFAS.
Unique Benefits of PFAS Annihilator
- Achieves near complete destruction of PFAS, regardless of carbon chain length or structure
- Generates few or no unwanted byproducts
- Equally effective on common organic co-contaminants (petroleum, hydrocarbons, chlorinated solvents)
- Mobile systems that can be deployed at or near the contamination source
- Uses inexpensive oxidation and neutralization chemicals
- Can operate on house or generator power and is not energy intensive
