POTENTIAL APPLICATIONS OF NANOMATERIALS IN WASTEWATER TREATMENT

Water scarcity is one of many alarming threats to its existence. The good quality water is among the chief challenges faced around the world. Acute actions are needed to access potable water globally. The generation of urban garbage due to tremendously populated and densely industrialized zones contributes to an excessive amount of contaminated waste products.   The accidental loss and mismanaged landfills are the leading reasons for the contamination of water. The release of all these contaminants in the water bodies surges an urgent need for the treatment of wastewater. The wastewater majorly comprises both inorganic pollutants (heavy metals, fluoride etc.) and organic pollutants (microbes, synthetic dyes, pharmaceuticals etc.). The reuse and recycling of wastewater can provide a salient contribution to retaining the water fresh. The traditional methods used for the remediation of contaminants didn’t generate satisfactory results, influencing the need for advanced technology and novel research which is sustainable, efficient, and environmentally friendly. Nanomaterials and technologies have been the prime subject of recent research for drafting better strategies for the treatment of wastewater. The nanotechnologies like filtration, adsorption, and catalysis are frequently employed for the systematic removal of contaminants.
