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. There are a variety of ...
Nanotechnology is expected to deal more efficiently with contaminants which convectional water treatment systems struggle to treat, including bacteria, viruses and heavy metals. This efficiency generally stems from the very high specific surface area of nanomaterials, which increases dissolution, reactivity and sorption of contaminants. [13] [14]
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

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.

Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
As nanotechnology advances, many studies have been conducted to determine the effects nanoengineered materials can have on the environment. [22] Most textiles can lose up to 20% of their mass during their lifetime, so nanoparticles used in production of nanofabrics are at risk of being released into the air and waterways.
