Water purification with nanotechnology uses carbon nanotubes for water filtration. It also uses nanosensors, such as those based on titanium oxide nanowires or palladium nanoparticles are used for analytical detection of contaminants in water samples.
The impurities that nanotechnology can tackle depend on the stage of purification of water to which the technique is applied. It can be used for removal of sediments, chemical effluents, charged particles, bacteria and other pathogens. Toxic trace elements such as arsenic, and viscous liquid impurities such as oil can also be removed using nanotechnology.
