Abstract
In the current scenario, the conservation of environment is an urge. Among various environmental hazards, the knocking area is waste water treatment. Scientists are constantly engaged in finding the advanced technology with high proficiency and low investment. One such technique called as nanotechnology has interesting application in the field of waste water treatment. However, information accessible is restricted. The present text reviews the application of various nano-materials for wastewater treatment techniques. The five main classes includes: First, Nano adsorbents like metal oxides, applied usually for removal of heavy metals. Second, nanomaterials of carbon used for effective adsorption and conduction process. Third, graphene-based nanoparticles for environmental remediation. Fourth, nanotubes have been used for effective removal of pollutants by means of, hybrid Nano membranes, Nano fibers and carbon nanotube membranes. Fifth is recyclable nano composites, mats, beads in water decontamination. Finally, some zero valent Nano sized metals showing strong adsorption capability and operational simplicity.This paper discusses the application of nanomaterials in wastewater treatment. Such nanomaterial’s which affordable, eco-friendly are, and efficiently work at large scale is the need of hour.
