Todd DeJournett (Minnesota), and James Wang (Maryland) co-authored a poster, entitled "Removal of Per and Polyfluorinated Alkyl Substances (PFAS) with RO and NF Membranes – Implications for Concentrate Management," which Todd will present at the American Membrane Technology Association's (AMTA's) Membrane Technology Conference & Exposition at the Palm Beach Convention Center in West Palm Beach, Florida at 5:00 p.m. on March 14, 2018.

Todd DeJournett is a Senior Engineer based in Minnesota with more than 15 years of professional experience focused in the areas of industrial water/wastewater treatment, drinking water treatment, aquatic chemistry, and remedial system design.

James (Yu-Sheng) Wang is a Principal Environmental Engineer based in Maryland with more than 18 years of experience focused on developing and applying innovative assessment and remediation technologies. James has built his practice by providing clients with cost-effective solutions specifically tailored to solving their most challenging problems.

For 2018, the American Water Works Association (AWWA) and AMTA have partnered with the Water Environment Federation and WateReuse Association to create the technical program. The program explores how the latest developments in membrane technology can enhance water reliability and quality. Each year the conference addresses new directions in water and wastewater treatment technologies, desalting, and membrane bioreactor applications.

The American Water Works Association is an international, nonprofit, scientific and educational society dedicated to providing total water solutions for the effective management of water. Founded in 1881, the Association is the largest organization of water supply professionals in the world. Their membership includes over 3,900 utilities that supply roughly 80 percent of the nation's drinking water and treat almost half of the nation's wastewater. Their nearly 50,000 total memberships represent the full spectrum of the water community: public water and wastewater systems, environmental advocates, scientists, academicians, and others who hold a genuine interest in water.

Abstract

The poster discusses per and polyfluorinated alkyl substances (PFAS), a class of compounds widely used in aqueous firefighting foam (AFFF) and consumer items. These compounds have been widely detected in surface water and groundwater sources. While initial human health and regulatory attention has been focused on perfluorinated compounds (PFCs) such as perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), a growing body of knowledge about the occurrence and persistence of PFAS in the environment continues to expand the list of PFAS receiving regulatory attention throughout the U.S. While RO membranes are capable of removing PFAS from drinking water, the resulting concentration of PFAS In the RO concentrate may present both a challenge for managing the concentrate and an opportunity to remove PFAS from the environment. Significant progress can be achieved through a transfer of technology, knowledge, and skills among professionals working in remediation, water utilities, and other areas to address this emerging and widespread environmental issue.
