ABSTRACT: Electrified membranes (EMs) possess the capacity to handle the intrinsic restrictions of traditional membrane techniques. EMs show improved functions beyond separation. Electrification can increase the efficacy and sustainability of membrane techniques and encourage novel utilizations in water and wastewater treatment. As a process in which chemical oxidants are produced in situ via redox reactions on the surface of an electrode, electrochemical disinfection (ED) has recently magnetized increased interest as an option to conventional chemical dosing disinfection techniques. In this review, we focus on fresh improvements in EMs, especially on water and wastewater disinfection. A brief description is accorded to materials categories, synthesis procedures, and electrified filtration operating modes. A discussion is dedicated to applications of EMs, especially water disinfection via bacterial and viral inactivation. Future challenges and promising applications for EMs are underlined. On the other hand, a brief description of ED concepts and perspectives is given. ED does not demand the transport and storage of hazardous materials and could be scaled across centralized and distributed treatment contexts; it shows promise for use both in resource-limited settings and as a supplement for aging centralized systems. This discussion suggests that EMs would be merged with ED as an intensified process.
