That's a misperception, asserted Jeff Green, CEO of NanoH2O, a desalination company that grew out of research at UCLA; 70 percent of the water that gets used goes to agriculture while 20 percent goes to businesses. Many of these companies have their own private purification systems.
"We are trying to make desalination competitive," Green said. In urban centers, water sells for around 25 to 50 cents a cubic meter. Water run through standard desalination processes sells for 50 cents to $1 per cubic meter. Nanotechnology and new membranes will bring the price down, he said.
