Description: Granular activated carbon (GAC) adsorption is the most widely employed technology to remove per- and polyfluoroalkyl substances (PFAS) from water. The collage submitted herewith highlights “the beauty of GAC texture.” One gram of activated carbon has an internal surface area that can be as large as a football field. Can you believe it just looking at this texture? These photos were taken in the Environmental Engineering Research Laboratory located in the new Fitts Woolard Hall while I was crushing and sieving GAC to obtain a range of particle size fractions. The different size fractions will be used to determine the intraparticle distribution of adsorbed PFAS, and results will help us understand mechanisms of PFAS adsorption. Photos show progressively smaller GAC size fractions, and the large photo depicts a pulverized slurry form of activated carbon.
