To remove these contaminants, advanced technologies based on <strong>adsorption using activated carbon and selective resins <\/strong>are employed, in configurations optimised to achieve treatment levels down to the <strong>ppt<\/strong> (<strong>parts per trillion<\/strong>) range.<\/p>\n<p><strong>PFAS Removal Technologies<\/strong><\/p>\n<p><strong>1. Activated carbon + single stage of selective resins (removal down to ppb levels)<\/strong><\/p>\n<ul>\n<li><strong>Granular activated carbon (GAC):<\/strong> adsorbs most long-chain PFAS (such as PFOS and PFOA), thereby reducing their concentration.<\/li>\n<li><strong>Single-stage selective resin filtration<\/strong>: removes residual PFAS, including short-chain PFAS, reducing concentrations to parts-per-billion (ppb) levels.<\/li>\n<li><strong>Typical application<\/strong>: wastewater treatment to ensure compliance with legal limits.<\/li>\n<\/ul>\n<p><strong>2.
