Advanced Application of Nanotechnology to Industrial Wastewater

Abstract

Domestic and industrial wastewaters have many pollutants, including organic and inorganic compounds. Many of the contaminants present in wastewater are harmful with negative impacts if they exceed permissible limits. To avoid the adverse effect of such pollutants on the environment and human beings, it is essential to treat wastewater to a permissible level before discharging it into water bodies. Several methods are available for wastewater treatment. The commonly used methods are solvent extraction, chemical precipitation, lime coagulation, reverse osmosis, ion exchange, adsorption, cementation, electrodeposition, etc. Adsorption is one of the most convenient and proven techniques for removing and treating many pollutants, including toxic metals from water and wastewater. Nanoparticles represent a promising new wastewater remediation technology because of their high treatment efficiency and cost-effectiveness, as they have the flexibility for in situ and ex-situ applications. The present chapter focused on nanotechnology and nanoparticles, various types of adsorbents for wastewater treatment, and aspects of adsorption using nanoadsorbents.
