Removal of Perfluoroalkyl Substances by PAC Adsorption and Anion Exchange [ Project # 4344 ]
@inproceedings{Dudley2015RemovalOP, title={Removal of Perfluoroalkyl Substances by PAC Adsorption and Anion Exchange [ Project \# 4344 ]}, author={Leigh-Ann Dudley and Elisa Arevalo and Detlef R. U. Knappe}, year={2015} }
1. Assess the effectiveness of commercially available PACs with a wide range of physicalchemical characteristics for PFAS removal 2. Determine whether enhanced PFAS removal can be accomplished with superfine PAC (SPAC) as a result of faster PFAS adsorption kinetics and/or a larger PFAS adsorption capacity 3. Evaluate the effects of resin type and dose as well as background water quality on PFAS removal by anion exchange 4. Identify regeneration conditions that restore the PFAS removal capacity…
