Hydrosil’s HS-PF is designed to remove per- and polyfluoroalkyl substances (PFAS). The media is selective for removing PFAS (PFOA, PFOS, FTCA, FTSA, FTOH). Based on the application, flow, concentration of the pollutants, granular activated carbon (GAC) or resin may be used to remove contaminates to non-detectable limits. Hydrosil’s HS-PF is an economical and efficient remediation process which removes both long and short chain perfluoroalkyl carbolic acids (PFCAs).
These emerging pollutants are commonly found in ground water from manufacturing facilities such as chemical, textiles, metal coating, automotive, as well as airports and air force bases.
Testing has shown that PFAS can be adsorbed into the inter-layer structure of the material for complete PFAS removal including PFOS and PFOA.
Per- and poly-fluorinate alkyl substances are both known as “PFAS” or the “Forever Chemicals”. PFAS is grouped into polymers and non-polymers. Both of these are man-made chemicals have been manufactured for centuries in food packaging, stain repellents, textiles, fire-fighting foam, cleaning products, and military training equipment. PFAS chemicals are beginning to be phased out in the United States in order to eliminate the use of PFOA contamination. PFOA and PFOS is still be manufactured internationally and used in consumer products. The unregulated PFAS compound is also known as “GenX” to the large American chemical company that use it in manufacturing process. Due to the unique molecular structure of PFAS—it is extremely difficult to break it down. Several water treatment processes are resistant to removing PFAS; Hydrosil’s HS-PF works to remove PFAS by means of ion exchange. Ion exchange is used to remove both short and long chain PFAS.
