Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) in Germany are testing two technologies designed to destroy per- and polyfluoroalkyl substances (PFAS) in water, according to a report.
The methods – hydrodynamic cavitation and cold atmospheric plasma – aim to break down the persistent chemicals rather than simply relocate them, officials said. Preliminary results showed that hydrodynamic cavitation degraded about 37% of perfluorooctane sulfonate (PFOS) in tap water, while the cold plasma method achieved near-complete breakdown of both long-chain and short-chain PFAS, the report stated.
