Desalinating process of water, although a necessity, is also an expensive process. Another concern is the huge amount of energy the process consumes, as it is requird to produce large amounts of pressure. Here is a relief for the water desalination industry — carbon-nanotube membrane. Yes, the Lawrence Livermore National Laboratory researchers have developed a carbon-nanotube membrane that is capable of desalinating water in an inexpensive process.
This new process using more-permeable nanotube membranes could also reduce energy costs by atleast 75 percent of the general desalination process.
According to the lab, the materials of the improved membrane are made of carbon atoms, arranged to form hollow nanotubes. These nanotubes are about 50,000 times thinner, compared to a human hair! A combination of billions of those nanotubes is used to act like pores on a silicon chip — the size of a quarter.
