Increasing scarcity and decreasing quality of freshwater sources for production of drinking water are common challenges faced by communities across the world. These challenges have incentivized the development of water treatment technologies that can: (1) effectively remove a broad range of contaminants from traditional (e.g., rivers and aquifers) and non-traditional (e.g., seawater and wastewater effluent) water sources; or (2) selectively remove specific contaminants of concern (e.g., per- and polyfluoroalkyl substances, PFAS). In this talk, we will discuss current work in our laboratory on treatment technologies of both types. Specifically, we will cover our research on electrically conductive membranes (ECMs; https://doi.org/10.1021/acs.estlett.3c00631), and sorbents for PFAS removal (https://ncpure.collaboratory.unc.edu/). The talk will include the practical motivation for the development of these technologies, the scientific gap our research addresses, and an overview of our progress on advancing these technologies and results to date.
