The increase in water consumption and the resulting shortage, aggravated by the pollution of water sources, has caused the supply of sanitary water to become one of the basic concerns of the world community. Considering the many capabilities of nanotechnology in removing and controlling environmental pollution and purifying and preventing its spread, it can be considered a green technology and an effective tool to achieve sustainable development. Entering this technology into the field of environmental protection and its practical use, especially in the field of water and wastewater treatment, and creating suitable conditions for the reuse of treated wastewater, is necessary considering the problems caused by the lack of sufficient and healthy water. Therefore, in this article, the applications of nanoscale particles in water purification to remove color, arsenic, nitrates, organic substances, and heavy metals, as well as the removal of specific pollutants from wastewater with the help of nanoceramics and the removal of pollutants from industrial wastewater by titanium oxide nanoparticles and the use Nanotubes have been investigated to trace the pollution of wastewater.
