Author : Rohit Patel

Abstract : Nanotechnology has emerged as a powerful tool in environmental engineering, particularly in the purification and treatment of water. This paper explores the application of nanomaterials such as nanoscale zero-valent iron (nZVI), carbon nanotubes, and nano-silver in water treatment processes. These materials exhibit unique properties, including high reactivity, large surface area, and strong antimicrobial capabilities, making them effective in removing contaminants such as heavy metals, organic pollutants, and pathogens. The paper reviews the mechanisms by which these nanomaterials interact with various pollutants and assesses their effectiveness in different water treatment scenarios. It also discusses the environmental implications of nanomaterial use, including potential toxicity and disposal challenges. Case studies highlight successful implementations of nanotechnology in water treatment facilities around the world. Finally, the paper identifies areas for future research and development to optimize nanomaterial performance and ensure their safe application in water purification.
