Enviro Wiki aims to be the go-to website for environmental information. US environmental programs such as the Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) fund cutting-edge environmental research projects. Here, articles written by invited experts (see Contributors) and edited by leaders in this field (see Editors) aim to introduce and summarize current knowledge for environmental project professionals on an array of topics, with cross-linked references to reports and technical literature. |
Featured article / Biodegradation - HydrocarbonsPhotoactivated Reductive Defluorination (PRD) is a PFAS destruction technology predicated on ultraviolet (UV) light-activated photochemical reactions. The destruction efficiency of this process is enhanced by the use of a surfactant to confine PFAS molecules in self-assembled micelles. The photochemical reaction produces hydrated electrons from an electron donor that associates with the micelle. These highly reactive hydrated electrons have the energy required to cleave fluorine-carbon and other molecular bonds resulting in the final products of fluoride, water, and simple carbon molecules. Since the reaction is performed at ambient temperature and pressure, there are limited concerns regarding environmental health and safety or volatilization of PFAS compared to heated and pressurized systems. Due to the reductive nature of the reaction, there is no formation of unwanted byproducts resulting from oxidative processes. The PRD reaction rate decreases in water matrices with high levels of total dissolved solids (TDS). The PRD reaction rate decreases in water matrices with very low UV transmissivity. Low UV transmissivity (i.e., < 1 %) prevents the penetration of UV light into the solution, such that the utilization efficiency of UV light decreases. Due to the first-order kinetics of PRD, destruction of PFAS is generally most energy efficient when paired with pre-concentration technologies, such as foam fractionation (FF), nanofiltration, reverse osmosis, or resin/carbon adsorption, that remove PFAS from water.
