* Title: In-situ Inactivation of Pathogens on Membrane Surfaces using Freestanding and Electrically Active Carbon Nanotube Films
* Abstract:
Inactivation of microbial pathogens is the critical risk management step during water and wastewater treatment. Despite municipal chlorination and secondary disinfection, opportunistic waterborne pathogens (e.g., Legionella spp.) persist in public and private water distribution systems. As a potential source of healthcare-acquired infections, this warrants the development of novel pathogen removal and inactivation systems. Although membrane technology has been widely applied to separate various constituents and recover valuable resources from water and wastewater, conventional membranes are not typically designed to inactivate microorganisms during water and wastewater treatment.
Carbon nanomaterials have been proposed to develop new technologies for the disinfection of pathogens and biofilm-resistant surfaces. In this study, free-standing and electrically conductive carbon nanotube (CNT) films are synthesized to create new strategies for in-situ microbial disinfection and the mitigation of biofilm development on membrane surfaces
