Contemporary Developments in Waste Water Treatment Technologies

Abstract

Water is the sole reason for the existence of life and prime nutrient to sustain it. So, it becomes extremely important to preserve wastewater to utilize it efficiently for various purposes. The methods and techniques that have the least investment capital, qualitative output, and environment-friendly content are desired. Such unaccustomed methods are our hope for a cleaner, safer, and brighter future. This chapter revolves around the methods employed to brawl the threats posed to the viability of water at earth from emerging contaminants and the efforts made by mankind to prevent it. Nanotechnology has potent attributes for water decontamination. Several nanotech-based devices, methods, and treatments have been used in recent times for wastewater treatment such as nanomembranes, nano photocatalysts, nano-cellulose, nano-absorbent, and nanocomposite materials. The chapter discusses these contemporary developments in nano-based technologies and the various advancements, which have been recently made in conventional techniques used for wastewater treatment technologies.
