Title:Industrial and aviation contamination – Looking upstream to prevent PFAS from impacting municipal wastewater
Author(s):McKeown, Patrick
Subject(s):per- and polyfluoroalkyl substances
Abstract:Presented by: Patrick McKeown, PE – Business Development at ECT2, Abstract: PFAS in municipal wastewater has become a concern for many municipalities in the US. As local residents naturally contribute PFAS to the system, focus should be placed on removing the higher PFAS concentration industrial sources from entering the waste stream. This can be accomplished by treatment on site, prior to discharging to the sanitary sewer. This abstract focuses on two applications of PFAS treatment prior to sanitary sewer discharge. A industrial manufacturer uses PFAS in their production of industrial goods. Their combined PFAS concentrations leaving the manufacturing plant are in the mg/l level. A pilot system is installed to study on site treatment options in preparation for a facilities upgrade. The pilot study looked at a variety of GAC and ion exchange resins to handle the heavy loading provided by the manufacturing facility. Not only were the extremely high levels of PFAS a complicating factor here, but the high background concentrations of heavy metals, TOC, oils and grease made for particularly challenging conditions. The pilot study at the manufacturing facility is still ongoing, but early results indicate a regenerable ion exchange system may be the best path forward for improving their industrial discharge water quality. Biography: After graduating from the University of Maine with a degree in Civil and Environmental Engineering, Mr. McKeown began his career in the environmental engineering field, focusing on wastewater and stormwater design. Mr. McKeown then joined ECT2 as an engineer on the design and fabrication team, building and operating systems treating PFAS contaminated water on project sites around the globe. After earning his Professional Engineering license in Maine, he transitioned to the business development team.
