New insights towards disinfecting viruses – short notes
Abstract
Water treatment specialists need more and more to understand how viruses behave in potable water pipes and wastewater setups. This work discusses the late advances in dealing with viruses present in water treatment processes. Activated carbon adsorption (ACA) remains one of the most efficient and credible physicochemical methods. Nanoparticles have been utilized to turn activated carbon into a more efficient sorbent. Membrane filtration could lead to total elimination of viruses and ensure the safety of drinking water plants. As a feasible utilization for disinfecting potable water, solar disinfection (SODIS) remains a green and cost-efficient technology with its optical and thermal pathways and deserves more interest in its large and industrial implementation. Identically, solar distillation remains a viable solution for disinfecting and treating water. The water treatment techniques that are currently utilized for surface water treatment are appropriate for eliminating viruses like influenza A viruses, as proved by the literature. More strict precautions have to be taken to secure viruses' total elimination from water and wastewater as for influenza A and H5N1 in terms of advanced oxidation processes, ACA, and membrane processes application. Before reaching surface water, pathogens have to be removed efficiently from hospital and municipal wastewaters. HIGHLIGHTS Waterborne pathogenic viruses constitute a grave menace to human health and life.; Coronaviruses’ behavior in water and wastewater processes has to be well examined.; Nanoparticles have been utilized to adjust activated carbon into more efficient sorbent.; Water treatment plants combining UV irradiation and membrane UF would allow excellent coronaviruses removal to be attained.; Advanced oxidation processes, solar disinfection, activated carbon adsorption, and membrane processes are promising towards viruses’ removal.;
