374Water Prepares Mobile AirSCWO System for April PFAS Pilot in Minnesota

SCWOSCWO

374Water will deliver its mobile AirSCWO supercritical oxidation system to St. Cloud, Minnesota, in April 2026 for pilot PFAS destruction on biosolids and spent granular activated carbon, running through mid-September. The unit leverages proven >99.95% PFAS destruction technology and processes both liquid and slurry waste streams on-site.

1. Mobile AirSCWO Deployment to St. Cloud

374Water is completing final preparations on its mobile AirSCWO supercritical water oxidation system for deployment to the City of St. Cloud’s Nutrient, Energy, and Water Recovery Facility in April 2026. The unit will undergo pilot operations through mid-September, processing PFAS-contaminated biosolids and spent granular activated carbon supplied by the facility. This marks the first on-site deployment of the company’s mobile waste destruction platform.

2. System Capabilities and Technology

The mobile AirSCWO system is engineered for rapid transport and on-site setup with minimal lead time, capable of processing both liquid and slurry waste streams including PFAS-contaminated biosolids, AFFF residues, and other organic wastes. It leverages the company’s proven supercritical water oxidation technology, which has demonstrated over 99.95% PFAS destruction in previous fixed installations. On-site remediation eliminates hazardous waste transport, reducing cost, liability, and logistical complexity for customers.

3. Strategic Waste Destruction Services Expansion

Introduced in 2025 as part of its Waste Destruction Services platform, the mobile offering complements existing fixed-site licenses, such as the five-year agreement in Orlando. This deployment model targets remediation projects, pilot programs, and industrial cleanups where permanent installations are impractical or transportation poses additional risks. The company anticipates significant demand from PFAS remediation, AFFF takeback initiatives, and industrial sites seeking on-site destruction solutions.
