Engineered For Impact: The Carbon That Stands Out In PFAS Treatment

Tightening PFAS regulations have raised the stakes for granular activated carbon (GAC) performance, pushing utilities to prioritize materials with high adsorption capacity, long bed life, and consistent removal of both long- and short-chain PFAS. Filtrasorb 400 meets these challenges through a unique agglomerated manufacturing process that blends rigorously selected metallurgical-grade bituminous coals, forming a dense, highly structured carbon granule with a wide distribution of micropores and mesopores. This engineered pore architecture—reflected in exceptionally high volumetric iodine and molasses values—provides superior adsorption of large, persistent molecules like PFOA and PFOS as well as TOC, taste and odor compounds, and other organics. Independent studies consistently show Filtrasorb 400 achieving dramatically longer bed life than enhanced coconut, lignite, or direct-activated carbons, maintaining concentrations below the 2-ppt MCL for tens of thousands more bed volumes. Its ability to be thermally reactivated with >99.9% PFAS destruction further reduces lifecycle costs and minimizes waste. With proven field and lab performance, Filtrasorb 400 gives water treatment plants a resilient, future-ready solution for meeting evolving drinking water standards.
