How nanotechnology can help solving water shortage problems
Supplying water to cities and towns has become an increasingly serious problem in many parts of the world. In many cases, long-term solutions must necessarily include wastewater reuse, but establishing a closed-loop water supply system is an extremely challenging problem, which involves a lot of political, economical and technological challenges. One of the major problems is the cost of the processes needed to remove tenacious organic contaminants from water – and this is where nanotechnology can help.
