374Water to Present New Supercritical Water Oxidation Destruction Data at WEFTEC 2026
374Water (NASDAQ: SCWO) will present new destruction-efficiency data for its AirSCWO supercritical water oxidation platform at WEFTEC 2026, the Water Environment Federation's annual technical conference, on September 30, 2026 in New Orleans.
The headline datasets show greater than 99.4% destruction and removal efficiency for every PFAS compound detected in a commercial-scale biosolids demonstration, 6PPD-Q reduced from an inlet concentration of 18 µg/L to non-detect (DRE greater than 99.99%), and greater than 99% COD removal across mixed pharmaceutical waste blends.
The presentation builds on an earlier Department of Defense-backed project in which AirSCWO destroyed more than 99.9% of PFAS in AFFF firefighting foam, supporting a federal procurement pathway the company is pursuing with partner Arcadis for sludge, biosolids, and emerging-contaminant destruction.
