Applications of Emerging Nanomaterials for Oily Wastewater Treatment

Abstract

The huge volume of oily wastewater produced from the industries has resulted in alarming environmental pollution and resource usage problems. A wide range of conventional and emerging approaches have been established to effectively reduce all these pollutants to an acceptable level to discharge the treated wastewater for reuse. Lately, nanomaterials have shown great potential to address this issue based on their unique and exceptionally properties such as high surface area, superhydrophilicity/hydrophobicity and surface functionalities. This chapter discusses the application of emerging nanomaterials for oily wastewater treatment. The characteristics of these nanomaterials and their hybrid or nanocomposites for oily water treatment are discussed. Finally, a brief future outlook and concluding remarks are presented.
