Emerging opportunities for nanotechnology to enhance water security
TLDR
New opportunities and approaches for the application of nanotechnology to enhance the efficiency and affordability of water treatment and wastewater reuse and enhance water security are considered.Abstract:
No other resource is as necessary for life as water, and providing it universally in a safe, reliable and affordable manner is one of the greatest challenges of the twenty-first century. Here, we consider new opportunities and approaches for the application of nanotechnology to enhance the efficiency and affordability of water treatment and wastewater reuse. Potential development and implementation barriers are discussed along with research needs to overcome them and enhance water security. This Perspective provides an overview of the potential aspects of water treatment and cleaning in which nanotechnology could play an important role.read more
