Abstract
In the present era of water resource scarcity, ever-increasing human demand for safe and clean water is a major prerequisite for a growing economy. It is now believed that present and future water challenges and their solutions will center upon future nanomaterial science developments. In this regard, the maturation and advancement of wastewater treatment technologies will require full competence and price effectiveness. Recent advancements in nanomaterial sciences have attracted great attention from scientists for the purposes of wastewater treatment. Within this context, this chapter summarizes these recent developments, centering on the potential advancements in nanotechnology for wastewater treatment. This chapter focuses on the utilization of different nanoadsorbents for wastewater treatment, including various nano-based adsorbents, for instance, activated carbon, carbon nanotubes, graphene, manganese oxide, magnesium oxide, zinc oxide, titanium oxide, and ferric oxides. These nanomaterials are frequently utilized for treatment of groundwater, surface water, and industrial wastewater which are contaminated due to toxic metals, organic and inorganic compounds, bacteria and viruses. Finally, the impact of toxic engineered nanomaterials on public health and the environment is briefly discussed.
