Background Adsorption is the main water treatment technology that is commercially used to remove per- and polyfluoroalkyl substances (PFAS) from water. These substances are in thousands of everyday products due to their high stability and chemical resistance, but are non-biodegradable and can pose risks to human health. Current adsorption techniques...

­Bacteria, viruses, and other harmful microorganisms pose a significant pathogenic health-related risk to safe drinking water. Disinfection by chlorination is commonly practiced, however, chlorine is a toxic chemical that typically requires careful storage and proper handling. While ultraviolet (UV) disinfection can be effective, UV-based processes...

Background Silver is a broad-spectrum biocide with high antimicrobial efficiency that is currently used on the International Space Station for disinfection of the water supplies. However, silver is known to react with some metallic components of water storage systems, which results in a gradual loss of biocidal silver ions over time in the water. This...

Silver Impregnated Graphene Oxide for Bromide Removal from Surface Water SI Case #M17-105P Background Bromide is widely present in natural waters, as well as in drinking water. Due to a wide variety of factors, bromide levels are increasing in both surface and ground waters. Because bromide itself is not known to pose any direct human or ecosystem...
