Nanotechnology for water purification

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 the process of manipulating atoms on a nanoscale.[1] In nanotechnology, nanomembranes are used for the purpose of softening water and removal of contaminants such as physical, biological, and chemical contaminants. There is a variety of techniques in nanotechnology that uses nanoparticles for providing safe drinking water with a high level of effectiveness. Some techniques have become commercialized.

For better water purification or treatment processes nanotechnology is preferred. Many different types of nanomaterials or nanoparticles are used in water treatment processes. Nanotechnology is useful in regard to remediation, desalination, filtration, purification, and water treatment.
