GAC in Removing PFAS
Granular activated carbon (GAC), made up of high carbon content such as wood, lignite, and coal, is considered one of the most effective solutions for removing PFAS (Per- and polyfluoroalkyl substances). GAC filter beds are used to remove it. The water is passed through the GAC filters, where the pollutants get adsorbed into the pores and the large surface area of carbon. The PFAS adhere to the GAC particles via chemical and physical interactions. It is more efficient in capturing long-chain PFA substances. Always choose Western Adsorbents & Catalysts, the largest activated carbon manufacturer in India. We supply the best quality of industrial-grade activated carbon to our customers. Our product range consists of activated carbon, garnet, aluminum balls, ceramic balls, and many more. Call us for more information on our products.
Key Factors Affecting GAC Performance
- Type of PFAS: GAC is more efficient in capturing long-chain PFAS than the short-chain variants.
- Time: There must be a long contact between GAC and PFAS-containing water for effective removal.
- Water Quality: The Presence of other pollutants, like organic compounds, may alter GAC performance.
- Carbon Type: Carbon from coconut shell and coal both will differ in performance. Also, lower quality of carbon is proven ineffective for performing any purification.
Application of Granular Activated Carbon
- Municipal Water Treatment Plant: GAC filters are used in ETPs and STPs to remove PFAS from the drinking water units. Here, large filters are employed where the water flows, and the PFAS gets adsorbed.
- Industrial Wastewater Treatment Plant: Industries often use or produce PFAS, and are not allowed to release this wastewater into rivers. Hence, they first treat the water with GAC systems. They help reduce environmental impact and regulatory liabilities by capturing PFAS.
