A new press release from Sunresin compares certified high-capacity PFAS resin against granular activated carbon (GAC) for removing per- and polyfluoroalkyl substances from water. The article highlights that GAC relies on physical adsorption and struggles with short-chain PFAS and background organics, while ion exchange resin uses chemical functional groups to bind both long- and short-chain compounds more effectively, with at least 30% higher operating capacity and faster flow rates. The release also covers certification standards like NSF/ANSI 61, media durability, and system design considerations, such as vessel footprint and empty bed contact time. Sunresin claims its resin handles high sulfate and nitrate levels without losing selectivity, making it a candidate for utilities needing to meet strict parts-per-trillion discharge limits. The piece is essentially a technical pitch for their product, but it offers a useful side-by-side for engineers evaluating PFAS treatment options.
