Carbon nanotubes as membrane

A second type of filter that has also been proven in principle, would utilize carbon nanotubes as membrane. Water molecules passing through the carbon nanotubes, with nanotubes of about 7 nanometers in diameter, as nanotubes have long slip-planes, enables flow rates that were found to be four to five orders of magnitude faster than those for conventional fluid flow predictions.

It was further demonstrated that the flow of water through carbon nanotube membranes can be controlled through the application of electrical current which gives the nanotube membranes an extremely high probability that they might one day be implemented for the desalination of water with a ten-thousand times greater efficiency than the current processes.
