An Innovative Plasma Technology for Treatment of AFFF Rinsate from Firefighting Delivery Systems

The DoD has nearly 4000 aqueous film forming foam (AFFF) delivery systems in aircraft hangars and on firefighting vehicles. To minimize future impacts, current AFFF formulations will be replaced with PFAS-free alternatives. During this switch over, significant amounts of PFAS containing rinsate will be generated as existing systems are cleaned. Therefore, it is critically important to develop a method to treat AFFF-containing rinsate.
The overall objective of this project is to demonstrate operation of a mobile plasma treatment system for the treatment of AFFF rinsate from firefighting delivery systems such as aircraft hangars or aircraft rescue and firefighting (ARFF) vehicles at DoD facilities.
