Water desalination nanotechnology.

Imidized graphene oxide composite cation exchange membrane with improved conductivity and stability for electrodialytic water desalination. Nanotechnology makes portable seawater desalination device possible nanowerk spotlight freshwater could become the oil of the 21st century scarce expensive and fought over while over 70 per cent of the earth s surface is covered by water most of it is unusable for human consumption. In the last three decades many researchers and engineers have focused on water management and desalination which has been of great interest to decision makers. Bring desalination technology to meet these requirements in the near future.

Nanofiltration is also becoming more widely used in food. Engineering natural systems for water purification next generation systems. Nanofiltration nf is a relatively recent membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater with the purpose of softening polyvalent cation removal and removal of disinfection by product precursors such as natural organic matter and synthetic organic matter. Molecular dynamics modeling of nano porous centrifuge for reverse osmosis desalination.

Recently new methodologies have been developed recently based on using nanotechnology for water desalination such as reverse osmosis ultra and nano filtration. Carbon nanotubes membranes nanofiber membranes nanoporous ceramics clays and micro nanofluidics. Nanotechnology is the process of manipulating atoms on a nanoscale. There are many water purifiers available in the market which use different techniques like boiling filtration distillation chlorination sedimentation and oxidation currently nanotechnology plays a vital role in water purification techniques.

Nanotechnology is concerned with structures or processes that can deliver benefits developed from substances at the nanoscale i e 10 9 m almutairi et al. In nanotechnology nano membranes are used with the purpose of softening the water. While there is lots of water around only a small portion of it is drinkable. Researchers are investigating nanomaterials for use in making salt water drinkable.

Today the desalination of salt water is a very expensive process but nanotechnology could change that. Also new technologies based on using solar concentrators for solar desalination have been developed. With the significantly improved water productivity and separation performance the desalination plant operators can take the full advantages featured by these nano enabled membranes to significantly reduce the capital and.
