Non Technical Summary
Perflourinated alkyl substances (PFAS) have been implicated as carcinogens and have emerged as contaminants of serious health and safety concerns. New cost-effective technolo-gies that reduce their contamination in industrial and other wastewaters and groundwater are key solutions to improving the quality of life, reducing environmental pollution and safe-guarding the health of people around the globe.Inexpensive and efficient mitigation technologies such as the ones proposed fill a market need. We will obtain partnerships with companies in the area of environmental technologies and bioremediation, especially with those experienced at commercializing new technologies and solutions. We have developed strong interest and partnership with two environmental engineering companies based in NY State. Ramboll US Consulting, Inc. and Environmental Engineering Solutions, PC, have provided support letters.Problem Statement: Per-fluoroalkyl substances (PFAS) can be removed by adsorption using granu-lar activated carbon (GAC) or Ion Exchange resins.1-3 However, interference of other organic matter present in the water presents a challenge for efficient removal. Also, short-chain (e.g., C4-C7) PFAS compounds are less likely to be removed.4-5 Documented PFAS adsorption to most media that have been tested to date is chain-length dependent, with sorption significantly lower and with break-through significantly faster for shorter-chain compounds.1, 6 Furthermore, concern over mobility and potential health effects of these shorter-chain compounds is increasing.7-9 Sustainable solutions to address a broader range of PFAS compounds under a wide range of contaminated water quality con-ditions are needed. We propose the investigation and comparison of two novel, regenerable media for improved sorption of PFAS compounds, with a particular focus on short-chain compounds.Objectives: The goal of this project is to advance the application of novel high-capacity sorbents for sustainable treatment of PFAS from diverse contaminated waters. Specific objectives include: (1) adapt and design novel sorbents to enable flow-through treatment of contaminated water; (2) evalu-ate their sorption capacity and kinetics in single compound and complex contaminated water matri-ces; and (3) develop sustainable sorbent regeneration approaches. This work will be focused on novel advanced adsorbates, namely metal-organic frameworks (MOFs) and zeolites. The performance of each new material class will be compared to state-of-the-art standard granular activated carbon (GAC).Awarded Project Start Date: 4/1/21Sponsor: Clarkson University
