Abstract:
... Stormwater reuse is one of the most important ways to mitigate water resource shortage. However, urban stormwater contains many bacteria species, which threaten the reuse safety. Therefore, stormwater disinfection is highly needed. Although disinfection has been widely conducted in the drinking water and reclaimed water, it is rarely carried out for stormwater. This study collected the roof stormw ...

Abstract:
... Two-dimensional Ag/WS₂ hybrid membranes were developed to improve separation performance of WS₂ membrane by in situ self-reduction of AgNO₃ on WS₂ nanoflakes. With the increase of Ag content in Ag/WS₂ hybrid membrane, water flux increased as well because of increased interlayer spacing and more irregular stacking of WS₂ nanoflakes, while the rejection rates for dye molecules decreased. The hybrid ...
