Nanotubte Technology: News for Filtering Contaminated Water Supplies

Lydon B. Johnson Space Center, Houston, Texa has developed Nanotube technology that can be used as a filtration device to eliminate contaminants from water supplies.

      Innovators have originally developed this to purify waste-water for reuse aboard the International Space Station.  It is considered to be applicable to many numerous situations on Earth where there is  need for potable, medical-grade water from a contaminated water supply.

"First, the water enters a device and contacts  the filter matrix, which can be made of polymer, ceramic, or metallic compounds.  Carbon nanotubes within the matrix allows only water molecules to pass through, leaving behind any larger molecules and contaminants.  Ah oscillator circuit attached to the filter matrix propagates acoustic vibration, further causing water molecules to de-bond and move through the filter  This use of acoustics eliminates dependence on gravity and thus filter orientation.  In effect, water moves through the device!
