Nanotechnology has emerged as a promising technology for water treatment in recent years. This review paper provides an overview of the different types of nanoparticles and nanomaterials used for water treatment, including metal nanoparticles, metal oxides, carbon-based materials, and Nano composites. It also discusses various water treatment methods that use nanoparticles or nanomaterials, such as filtration, adsorption, Photocatalysis, and disinfection.

The applications of nanotechnology in different areas of water treatment, such as industrial wastewater treatment, drinking water purification, and seawater desalination, are also discussed. Furthermore, the review evaluates the performance of nanotechnology-based water treatment methods in terms of effectiveness, efficiency, and cost-effectiveness.

The potential environmental and health impacts associated with the use of nanoparticles or nanomaterials in water treatment are also reviewed, including the release of nanoparticles into the environment and their potential toxicity. Finally, the current challenges and opportunities for further research and development in the field of nanotechnology for water treatment are discussed, including the development of sustainable nanomaterials, optimization of treatment processes, integration with existing water treatment methods, understanding environmental and health impacts, and commercialization and scaling up of nanotechnology-based water treatment methods.
