Water Desalination Nanotechnology

While there is lots of water around only a small portion of it is drinkable.

Water desalination nanotechnology.

Molecular dynamics modeling of nano porous centrifuge for reverse osmosis 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. 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. Engineering natural systems for water purification next generation systems.

In nanotechnology nano membranes are used with the purpose of softening the water. 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. Today the desalination of salt water is a very expensive process but nanotechnology could change that. A convergence between nanotechnology and membrane technology has led to revolutionary advances in water desalination.

Nanofiltration is also becoming more widely used in food. Nanotechnology is the process of manipulating atoms on a nanoscale. Tiange li qingsong tu shaofan li. 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.

Recently new methodologies have been developed recently based on using nanotechnology for water desalination such as reverse osmosis ultra and nano filtration. Low environmental impact low energy intensive and high efficiency omicro nanotechnology in water purification. Carbon nanotubes membranes nanofiber membranes nanoporous ceramics clays and micro nanofluidics. According to the usgs united states geological survey our oceans contain about 96 5.

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. Imidized graphene oxide composite cation exchange membrane with improved conductivity and stability for electrodialytic water desalination. Researchers are investigating nanomaterials for use in making salt water drinkable.
