Efficient waste water treatment is a key prerequisite for a growing economy during a time of water constraints. It is necessary to develop and execute novel waste treatment technologies with high efficiency and minimal cost. Recent advanced processes in the sciences of nano-materials drew several remedies from scientists. However, limited community information is available in this setting. The present essay analyses potential advances in nanotechnology in wastewater treatment. The research assessed and analysed the application of many kinds of nano-materials for wastewater treatment. This includes four main categories. Nano adsorbents such as carbon, carbon nanotubes, grapheme, manganese oxide, zinc oxide, titanium oxide, magnesium oxide and ferric oxides are first and foremost extensively used for heavy metal extraction. This includes four fundamental categories. Secondly, nano-catalysts including photocatalyst, electric catalyst, Fenton-based catalyst and chemical oxidizer have showed promise for the elimination of organic and inorganic contaminants. Thirdly, nano-membrane was employed for effective dyes, heavy metals and foulant removal, which included carbon nanotube membrane, electrospun nano-fibers and hybrid nanomembrane. In conclusion, nanotechnology integration is explored with respect to wastewater potential, using bioreactive algal membrane, anaerobic digestion and microbial fuel cell.
