Nanotechnology in Water and Waste Water Treatment

The third world war will be for water is said by researchers.

The long-term development of the global water situation is closely connected to the growth of the world population and global climate change.A group of leading climate impact researchers have shown that climate change possibly exacerbates the regional and global water scarcity.

They predict that global warming of 2(deg)C above present temperatures will confront an additional approximately 15% of the global population with a severe decrease in water resources and will increase the number of people living under absolute water scarcity (<500 m3 per capita per year) by at least another 40% compared with the effect of population growth alone.

An overview of recent advances in nanotechnologies for water and wastewater processes is provided, including nano based materials, processes, and their applications.

Besides the promising technological enhancements, the limitations of nanotechnology for water applications, such as laws and regulations as well as potential health risks, are reported in this book.
