Application of Nanomaterials in Treatment of Waste Water

  • Ajay Kumar Upadhyay

Abstract

To support life, clean water is one of the most essential things for all living species. Pollution in water from multiple harmful pollutants has been one of the world's most severe issues. For living organisms, marine toxins are also very harmful, and often affect the environment. Various processes, involving chemical precipitation, ion-exchange, adsorption, membrane filtration, coagulation-flocculation, flotation and electrochemical approaches, have been used to process water and waste water.With its uses in almost all areas of science and technology, nanotechnology has evolved dramatically over the past few decades and numerous nanomaterials have been designed for water remediation. Due to improved adsorption and/or photocatalytic activity, several nanomaterials ultimately offer a promising alternative to traditional methods of treatment. Different nanomaterials that have been used for water decontamination have been investigated in the current review article. Particular focus has been on the adsorption, photocatalytic and antibacterial function of nanomaterials in the thisstudy.
