Clarkson-GSI Team Conducts First Field Demonstration of Plasma Technology for PFAS Treatment


Clarkson University and GSI Environmental recently completed the first field demonstration of an innovative plasma-based technology for the treatment of water containing per and polyfluoroalkyl substances (PFAS). The field demonstration was successfully conducted at Wright-Patterson Air Force Base and is part of ongoing Air Force efforts to identify potential cost-effective and sustainable environmental solutions for treating groundwater containing PFAS.

This technology, called the Enhanced Contact Plasma Reactor, destroys PFAS by concentrating these compounds at the gas-liquid interface. Plasma is generated at that interface, which then destroys PFAS, requiring no additional chemicals or waste. During the field demonstration, hundreds of gallons of PFAS-impacted groundwater were treated, and various operating conditions were tested to optimize efficiency of mobile plasma treatment unit.

GSI collaborated with Clarkson researchers and plasma reactor developers, Drs. Selma Mededovic and Tom Holsen, to transition the technology from the laboratory to field-scale implementation. Key GSI team members include:

·         Dr. Stephen Richardson (Co-Principal Investigator);
·         Poonam Kulkarni (Lead Design Engineer); and
·         Taylor Borgfeldt (Field Technical Lead).
