ABSTRACT
The article reports on a robust free standing titanium dioxide (TiO2) nanofibre membrane developed by a team of researchers in Singapore which, they believe, could be a cost and energy efficient way of cleaning wastewater. It cites the advantages of the TiO2 nanofibre membrane such as concurrent membrane filtration for separation purposes and a higher acid/basic and temperature resistance. It discloses the potential of the TiO2 nanofibre membrane to be applied in a large amount of water and wastewater treatment uses.
