Emerging membrane technologies and disinfection methods for efficient removal of waterborne pathogens during the COVID-19 pandemic and post-pandemic

Abstract

Viruses and other microorganisms can enter water sources from different routes and cause pollution and irreparable damage. So, cost-effective and efficient systems for providing safe water are necessary. Efficient filtration systems based on antimicrobial materials have received a lot of attention in this regard. A wide range of materials play an important role in the production of efficient water filtration systems. Metal and metal oxide particles with anti-viral and antimicrobial properties comprising Cu, Cu₂O, Ag, TiO₂, and ZnO play a valuable role in the preparation of water filtration systems. Biopolymers such as cellulose or carbon nanomaterials like graphene or its derivatives have been reported to provide safe water. In this review, we summarize the use of diverse materials in the preparation of efficient filtration-based systems like membranes and paper filters for water treatment. Pathogen-containing water samples were effectively disinfected using the prepared water disinfection systems.
