Wastewater Treatment Through Nanotechnology: Role and Prospects

Abstract

Water is a most crucial and limited resource on the Earth, which has contaminated due to the addition of heavy metals, pathogens, pesticides, and many organic and inorganic substances. Currently, the research has been focused on the sustainable remediation approach for waste reclamation. Therefore, an affordable technology of wastewater treatment could tackle the problem of water. Nanotechnology is an efficient, affordable, effective, and durable method for water treatment. Nanomaterials have several properties such as specific surface area, high reactivity, high degree of functionalization, size-dependent properties, etc., which make them appropriate materials in wastewater treatment. The present chapter comprehensively describes the characteristics of different nanomaterials and their role in the restoration of aquatic ecosystem.
