Granular activated carbon and ion exchange are two technologies proven effective in treating waters that contain PFAS.One issue with both is that, as in other applications, the carbon or ion exchange resin accumulates the pollutants and then must be either regenerated or disposed of responsibly. De Nora now offers GAC and ion exchange treatments that reduce PFAS to nondetectable levels.The company’s preconfigured SORB systems include a regenerable multi-use ion exchange technology now being pilot tested. It can be paired with electrochemical advanced oxidation processes, significantly prolonging resin use and reducing the need for media disposal.The GAC and ion exchange systems
