Currently nanotechnology plays a vital role in water purification techniques. Nanotechnology is the process of manipulating atoms on a nanoscale. [ 1 ] In nanotechnology, nanomembranes are used with the purpose of softening the water and removal of contaminants such as physical, biological and chemical contaminants.
Applications of nanotechnology – Uses for technology on very small scales; Nanomaterials – Materials whose granular size lies between 1 and 100 nm; Nanotechnology – Technology with features near one nanometer; Ultrafiltration – Filtration by force through a semipermeable membrane; Reverse osmosis – Water purification process
A product called AMRIT, meaning elixir in Indian languages, developed by the Indian Institute of Technology Madras, is an affordable water purification technology based on advanced materials, which has been validated through research articles [52] [53] and patents [54] and has been approved for national implementation in India. The technology ...
Nanotechnology offers the potential of novel nanomaterials for the treatment of surface water, groundwater, wastewater, and other environmental materials contaminated by toxic metal ions, organic and inorganic solutes, and microorganisms. Due to their unique activity toward recalcitrant contaminants, many nanomaterials are under active research ...
These chelating groups hold tightly onto Hg (II) ions, removing it from the water. When purifying mercury from sea water, a decrease in the volume to surface area ratio leads to a decline in the efficiency of the elimination.7 Cost efficiency of the nanotrap process is indicated in the fact that the materials can be reused to recycle more water.
Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.
Nanoremediation has been most widely used for groundwater treatment, with additional extensive research in wastewater treatment. [5] [8] [9] [10] Nanoremediation has also been tested for soil and sediment cleanup. [11] Even more preliminary research is exploring the use of nanoparticles to remove toxic materials from gases.

The water can also flow down the outer surface of the tubes, but flow through the inside of the tubes is the fastest. This system is thought to be useful in water purification and desalination because of the accelerated water flow, as well as the nanotubes' ion-exclusion properties.
