Chapter 15 - Application of emerging nanomaterials in water and wastewater treatment

Abstract

Water resources contamination has an overall impact and is a cause of worldwide concern; thus the requirement for clean water is increasing. Nanotechnology may offer effective techniques for the treatment, utilization, and reuse of water and improve the next-generation water supply frameworks. With progress in nanotechnology, various nanoparticles are emerging for water filtration and wastewater treatment technologies due to their viability against synthetic and natural toxins. The excellent characteristics and viability of nanoparticles make them especially appropriate for water purification and wastewater treatment. This chapter discusses the utilization and applications of nanoscale particles being assessed or created as efficient materials for the purification and treatment of water. Nanoparticles are inherently preferable due to their effective performance over different materials utilized in the purification of water, as they have a higher surface area. Owing to such attributes, these might be utilized on a larger scale for water treatment in the future. The current outlook of nanoparticles in water treatment includes membrane fabrication, adsorption, photocatalysis, and disinfection. There are a couple of difficulties with utilizing nanoparticles; however, these difficulties are surmountable. In any case, nanoparticles are promising new-age solutions with excellent and eminent possibilities for water treatment.
