Refreshing news about drinking water

Abstract:
Accelerating Technology has reported that researchers at Lawrence Livermore National Laboratory have developed a new membrane material which could revolutionize water purification technology for the long term and reduce the cost of desalination by as much as 75%, when compared with reverse osmosis systems. Reverse osmosis is the current standard water purification technology, which involves forcing water molecules through a restrictive membrane. The lab's new carbon nanotube membranes sort molecules by size and using electrostatic forces. Although the new membranes have reduced pore size, they allow the same flow-through volume as the current, less restrictive membranes. The development could mean energy savings, as less force is required to accomplish standard flow rates. Researchers say the carbon nanotube membrane also holds promise for applications in capturing and reducing carbon dioxide emissions from power plants and similar operations.
