AI Technical Summary
Technical Problem
Conventional methods for removing PFAS from water and soil are resource-intensive and require significant amounts of energy and complex equipment.
Method used
Exposing a stream containing PFAS to pressurized carbon dioxide, such as supercritical carbon dioxide, to transfer at least a fraction of PFAS to the carbon dioxide, followed by separation, utilizing a carbon dioxide circulation loop for continuous extraction without releasing carbon dioxide into the environment.
Benefits of technology
Achieves efficient PFAS removal with reduced resource consumption and environmental impact, allowing for cost-effective and continuous operation.

Abstract
Method of extracting per- and polyfluoroalkyl (PFAS) from a stream, comprising the steps of: - providing pressurized carbon dioxide in a container; - providing the stream into the container, wherein the stream comprises PFAS and a liquid; - exposing the stream comprising PFAS to the pressurized carbon dioxide in the container such that at least a fraction of the PFAS in the stream is transferred from the stream to the pressurized carbon dioxide; and - separating the stream and the pressurized carbon dioxide comprising at least a fraction of the PFAS.
