AirSCWO™ is a physical-thermal process powered by water above its critical point (374°C and 221 bar) and air that yields a highly effective oxidation reaction that completely eliminates organic compounds. The reaction generates energy and safe products that can be recovered and reused.
Supercritical Water Oxidation (SCWO)
What is Supercritical Water Oxidation?
how it works
AirSCWO™ harnesses an efficient decentralized solution for treating a broad range of waste feedstocks rapidly, continuously, cost-effectively and with unprecedented reliability.
374Water’s AirSCWO™ Systems are compact, modular, and prefabricated units that are energy efficient and cost effective.

our customers say
We saw early on that supercritical water oxidation (SCWO) may change how waste is managed. Our commitment, investment, and execution are part of our corporate culture to make the world itself a better place.
Clean water is not a luxury – it’s fundamental to the health and safety of our communities. I am glad I was able to visit 374Water and see the hard work they are doing to eliminate PFAS contamination from our water supply.
We took notice of 374Water and their supercritical water oxidation (SCWO) process early on, identifying this technology’s potential. Stantec has long been at the forefront in sustainable resource recovery.
OC San is an environmental agency whose mission is to protect public health and the environment, and a leader in the industry. The AirSCWOTM project is just another example of our long history of researching new and innovative technologies to improve wastewater treatment and resource recovery.
