Abstract- Adequate supply of clean, safe and potable water on a
regular basis, are the main issues faced by the people nowadays. To
achieve this objective wastewater should be treated so that it can be
reused as well as environment should be saved by the negative effect
of the untreated wastewater. This paper has focused on the different
types of nanomaterials used by nanotechnology that can help in
wastewater remediation. It is evident from the literature that this
technology is having lots of advantages over conventional methods
but still needs lots of research before the successful industrial
application.
