Abstract
Water purification is of great significance to alleviate water shortage and pollution problems throughout the world. In this work, we develop an electric field (EF)-assisted multifunctional one-step dynamic water filtration and disinfection system based on a vertical graphene-modified glass fibre filter (EF-VG-GFF). Benefiting from the dense and sharp nanowall structures of VG and the localized enhanced EF, the EF-VG-GFF purification system innovatively functions as a filter and an electroporation-disinfection system to simultaneously realize the physical interception and irreversible physiological inactivation of bacteria. As a result, >3.7 log removal efficiency (nearly 99.99% disinfection) is achieved for various examined bacteria under a voltage of several orders of magnitude lower than that in traditional electroporation-disinfection systems, and at a fast treatment speed of 2000 L h m equivalent to only 0.36 s retention time. The excellent purification performances, along with time and energy efficiency, byproduct-free and safety advantages, make the EF-VG-GFF system a competitive choice for the development of high-efficiency, low-cost, and eco-friendly water purification.
