How PFAS Can Be Eliminated with AirSCWO™ Technology

374Water’s AirSCWO™ system is a scalable and commercial solution that can be used to treat PFAS contamination at scale. The system is also highly energy efficient, which reduce the cost of treatment substantially.

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been used in a variety of products for decades, including firefighting foams, non-stick coatings, and food packaging. PFAS are known to be persistent in the environment and can bioaccumulate in humans and animals. They have been linked to a number of health problems, including cancer, liver damage, and reproductive problems.

In recent years, there has been growing concern about the presence of PFAS in the environment. PFAS have been detected in water supplies, soil, and air. In the United States, PFAS have been found in the drinking water of over 2,000 communities.

The U.S. Environmental Protection Agency (EPA) has taken steps to address the growing problem of PFAS contamination. In 2016, the EPA issued a health advisory for PFOA and PFOS, two of the most common PFAS. The health advisory recommends that people limit their exposure to PFOA and PFOS to 70 parts per trillion (ppt). In early 2023 the EPA announced plans for new regulation on wastewater and PFAS limitations.

While the EPA works to develop regulations, municipalities in the United States are looking for ways to address PFAS contamination including new technologies and solutions such as 374Water’s AirSCWO™ system. AirSCWO™ is a type of supercritical water oxidation(SCWO) process that can destroy PFAS at high temperature and pressure. The AirSCWO™ system has been shown to be effective in destroying a wide range of PFAS, including PFOA and PFOS.

374Water’s AirSCWO™ system is a scalable and commercial solution that can be used to treat PFAS contamination at scale. The system is also highly energy efficient, which reduce the cost of treatment substantially.

The system has been found successful to treat PFAS contamination for municipal wastewater, industrial and military waste.

The AirSCWO™ system is a safe and effective technology that can be used to treat PFAS and other ‘forever chemicals’. The system is scalable, modular, and energy efficient, making it ideal for municipalities in the US.

How the AirSCWO™ System Works:

The AirSCWO™ system uses supercritical water oxidation (SCWO) to destroy PFAS. SCWO is a process that occurs when water is heated to a temperature of over 374 degrees Celsius and a pressure of over 221 atmospheres. Under these conditions, water changes from a liquid to a supercritical fluid. Supercritical water has properties that make it an effective solvent for PFAS.

The AirSCWO system is highly efficient at destroying PFAS. Studies have shown that the system can destroy over 99% of PFAS.

AirSCWO is a completely safe technology. The system is enclosed in a chamber that prevents the release of any hazardous materials into the environment.

The AirSCWO™ system is scalable, modular, energy efficient, and highly effective. The AirSCWO system is a valuable tool for municipalities that are looking to address the growing problem of PFAS contamination.
