Title: Electrochemical technologies for per‐ and polyfluoroalkyl substances mitigation in drinking water and water treatment residuals
Abstract Water treatment technologies are needed that can convert per‐ and polyfluoroalkyl substances (PFAS) into inorganic products (e.g., CO2, F−) that are less toxic than parent PFAS compounds. Research on electrochemical treatment processes such as electrocoagulation and electrooxidation has demonstrated proof‐of‐concept PFAS removal and destruction. However, research has primarily been conducted in laboratory matrices that are electrochemically favorable (e.g., high initial PFAS concentration [μg/L–mg/L], high conductivity, and absence of oxidant scavengers). Electrochemical treatment is also a promising technology for treating PFAS in water treatment residuals from nondestructive technologies (e.g., ion exchange, nanofiltration, and reverse osmosis). Future electrochemical PFAS treatment research should focus on environmentally relevant PFAS concentrations (i.e., ng/L), matrix conductivity, natural organic matter impacts, short‐chain PFAS removal, transformation products analysis, and systems‐level analysis for cost evaluation. Article Impact StatementElectrochemical treatment is capable of destroying per‐ and polyfluoroalkyl substances, but future research should reflect more realistic drinking water sources.  more » « less

    Per- and Polyfluoroalkyl Substances (PFAS) are an emerging class of persistent organic pollutants. Although their thermal/chemical stability and water/stain repellence enable their widespread use in various products, such as personal care products, food packaging and firefighting foams, these properties also make them particularly resistant to degradation. This unwelcome persistence, with their trace concentrations, environmental prevalence, bioaccumulation and probable toxicities, poses a potential threat to environmental and human health. As such, much work is directed to finding ways to efficiently abate PFAS in the environment. Per- and Polyfluoroalkyl Substance Treatment Technologies provides a thorough review of the current state of research in treatment technologies for removing PFAS from the environment, particularly water. Beginning with a brief introduction to PFAS challenges and research needs, it covers established and promising technologies for PFAS removal from drinking water, wastewater, and groundwater. This is a great book for environmental engineers, environmental chemists, and industrialists interested in pollution remediation.

    Abstract Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are now widely found in aquatic ecosystems, including sources of drinking water and portable water, due to their increasing prevalence. Among different PFAS treatment or separation technologies, nanofiltration (NF) and reverse osmosis (RO) both yield high rejection efficiencies (>95%) of diverse PFAS in water; however, both technologies are affected by many intrinsic and extrinsic factors. This study evaluated the rejection of PFAS of different carbon chain length (e.g., PFOA and PFBA) by two commercial RO and NF membranes under different operational conditions (e.g., applied pressure and initial PFAS concentration) and feed solution matrixes, such as pH (4–10), salinity (0‐ to 1000‐mM NaCl), and organic matters (0–10 mM). We further performed principal component analysis (PCA) to demonstrate the interrelationships of molecular weight (213–499 g·mol−1), membrane characteristics (RO or NF), feed water matrices, and operational conditions on PFAS rejection. Our results confirmed that size exclusion is a primary mechanism of PFAS rejection by RO and NF, as well as the fact that electrostatic interactions are important when PFAS molecules have sizes less than the NF membrane pores. Practitioner PointsTwo commercial RO and NF membranes were both evaluated to remove 10 different PFAS.High transmembrane pressures facilitated permeate recovery and PFAS rejection by RO.Electrostatic repulsion and pore size exclusion are dominant rejection mechanisms for PFAS removal.pH, ionic strength, and organic matters affected PFAS rejection.Mechanisms of PFAS rejection with RO/NF membranes were explained by PCA analysis.

    Per- and polyfluoroalkyl substances (PFAS) are pollutants that have demonstrated a high level of environmental persistence and are very difficult to remediate. As the body of literature on their environmental effects has increased, so has regulatory and research scrutiny. The widespread usage of PFAS in industrial applications and consumer products, complicated by their environmental release, mobility, fate, and transport, have resulted in multiple exposure routes for humans. Furthermore, low screening levels and stringent regulatory standards that vary by state introduce considerable uncertainty and potential costs in the environmental management of PFAS. The recalcitrant nature of PFAS render their removal difficult, but existing and emerging technologies can be leveraged to destroy or sequester PFAS in a variety of environmental matrices. Additionally, new research on PFAS remediation technologies has emerged to address the efficiency, costs, and other shortcomings of existing remediation methods. Further research on the impact of field parameters such as secondary water quality effects, the presence of co-contaminants and emerging PFAS, reaction mechanisms, defluorination yields, and the decomposition products of treatment technologies is needed to fully evaluate these emerging technologies, and industry attention should focus on treatment train approaches to improve efficiency and reduce the cost of treatment.

    Per- and polyfluoroalkyl substances (PFAS) are notable health concerns, leading to global drinking-water regulations for primary PFAS. However, conventional drinking-water treatment methods are ineffective in eliminating PFAS due to their resistance to such processes. Moreover, certain disinfection procedures may inadvertently generate perfluorinated compounds from polyfluorinated precursor compounds. With evolving regulations, there exists an immediate demand for both technical and non-technical solutions that water treatment facilities can adopt. Here, to address this critical gap, we examine the primary challenges tied to PFAS removal and introduce a detailed four-stage protocol. We advocate for non-technical strategies to improve PFAS removal practices. The treatment trains and management recommendations presented in this Perspective are also geared towards helping utilities comply with regulations concerning other chemical contaminants, including disinfection by-products. We emphasize the necessity for practical PFAS monitoring and treatment guidelines and encourage utilities to leverage all available resources, to positively impact public health through improved water quality.

    Because of their ubiquitous presence in the environment and their potential toxicity to human health, per- and polyfluoroalkyl substances (PFAS) have drawn great attention over the past few years. Current conventional drinking and wastewater treatment approaches fail to effectively remove these substances from aqueous media, motivating researchers to focus on using sorption, a simple and cost-effective method, to remove PFAS from contaminated water. This work aims to summarize and critically evaluate the sorption capacities of PFAS by a variety of natural and engineered sorbents, including carbonaceous materials, ion exchange resins, polymers, different natural materials and other engineered sorbent materials. The specific focus of this review is on the performance of these different materials in removing short-chain PFAS due to their high solubility and mobility in aqueous media. A treatment train optimizing the removal of these short-chain substances from water is proposed, and challenges and future recommendations are discussed.
