PFAS challenge continues to drive R&D

摘要

The increasing number of patent applications promising to tackle the problem of PFAS in water sources neatly reflects the issue's ever-growing profile. While recent applications have detailed alternatives to the current leading technologies of ion exchange and activated carbon, the latter's performance on PFAS removal is receiving welcome attention. The giant of the industry, Calgon Carbon, has been trialling both activated and reactivated carbon impregnated with magnesium oxide or containing a higher calcium content, supposedly attaining higher removal rates of certain kinds of PFAS.
