“…Chemical disinfection, e.g., with chlorine, is the most common way of disinfection. However, higher doses are normally required to destroy virus as compared to bacteria, and chlorination may also lead to toxic by‐products (e.g., trihalomethanes and haloacetic acids) as well as residual infectivity depending on the water quality . An increased reliance on UV light for water disinfection has raised the concerns for viral resistance, especially related to adenovirus infection, which is especially problematic for immunocompromised population, e.g., in cancer and bone marrow transplant patients .…”

Access to drinking water is one of the greatest global challenges today. In this study, the virus removal properties of mille‐feuille nanocellulose‐based filter papers of varying thicknesses from simulated waste water (SWW) matrix are evaluated for drinking water purification applications. Filtrations of standard SWW dispersions at various total suspended solid (TSS) content are performed, including spiking tests with 30 nm surrogate latex particles and 28 nm ΦX174 bacteriophages. Filter papers of thicknesses 9 and 29 µm are used, and the filtrations are performed at two different operational pressures, i.e., 1 and 3 bar. The presented data using SWW matrix show, for the first time, that a filter paper made from 100% nanocellulose has the capacity to efficiently remove even the smallest viruses, i.e., up to 99.9980–99.9995% efficiency, at industrially relevant flow rates, i.e., 60–500 L m −2 h −1 , and low fouling, i.e., V max > 10 3 –10 4 L m −2 . The filter paper presented in this work shows great promise for the development of robust, affordable, and sustainable water purification systems.

“…This relatively long survival may reflect either the greater stability of the virus or the fact that the virus was added in the form of a fecal suspension, which imparted a high degree of "pollution" to the stored sample. Gilcreas and Kelly (16) recently investigated the survival of Coxsackie and Theiler's virus in both water and sewage. Their results and those reported here are hardly comparable because of differences in initial virus concentrations and other technical details, but in general, there is agreement with respect to temperature effects on survival times.…”
