Nanotechnology in Water Treatment

Nanotechnology refers to a wide range of tools, expertise and applications that simply involve particles on the approximate size scale of a few to hundreds of nanometers in diameter. Particles of this size have some distinct physicochemical and surface properties that lend themselves to novel uses. Indeed, advocates of nanotechnology suggest that this field of research could contribute to solutions for some of the major problems we face on the global scale such as ensuring a supply of safe drinking water for an emerging population, as well as addressing issues in medicine, energy, and agriculture.
