The University of British Columbia has developed a new technology that can filter out and destroy PFAS, known as “forever chemicals,” ubiquitous in contaminated water and linked to various health problems.
PFAS are in foams and sprays used by firefighters to combat blazes, which can leech into groundwater and contaminate drinking water, particularly in areas without proper filtration equipment.
The adsorbing media in the technology captures up to 99% of PFAS particles, which can be regenerated and potentially reused, preventing the creation of more toxic solid waste. The captured particles are then destroyed through electrical and photochemical processes.
The researchers are now preparing to conduct a real-world test of the technology in several locations in British Columbia, aiming to optimize it further and make a product for municipalities, industry, and individuals to use to eliminate PFAS in their water. This technology could provide a cheap and effective solution to remove PFAS from contaminated water sources.
