Innovations in Nanotechnology for Water Treatment

The long-term development of the global water situation is closely connected to the growth of the world population and global climate change. The constant growth of the world’s population, which is forecasted to nearly double from 3.4 billion in 2009 to 6.3 billion people in 2050, is attended by a predicted needed growth of agriculture production of 70%, by 2050. Thus, the demand for freshwater is growing dramatically, in particular for food production, since 70% of the world’s freshwater withdrawals are already accounted for by agricultural irrigation. Currently, 64 billion cubic meters of fresh water are progressively consumed each year.
