Water is the most important asset of human civilization, and clean water supply is a basic human necessity. Due to the population growth and climate change, challenges in meeting global water needs require novel water treatment technologies in order to ensure the drinking water supply and reduce global water pollution. To overcome this situation, highly advanced nanotechnology can be adapted to develop new opportunities in technological developments for advanced water and wastewater technology processes. This chapter is an overview of recent advances in nanotechnologies for water and wastewater treatment processes, including nanobased materials, such as nanoadsorbents, nanometals, nanomembranes, and photocatalysts. These materials have favorable properties when compared with conventional processes reported. This chapter overviews advances in nanotechnologies for water and wastewater treatment processes, including nanobased materials, such as nanoadsorbents, nanometals, nanomembranes, and photocatalysts. Nanoparticles are expected to play a crucial role in water purification. In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and germs. Conventional desalination methods are energy-consuming and technically demanding, whereas adsorption-based techniques are simple and easy to use for water purification devices, yet their capacity to remove salts is limited. Next-generation drinking water purification devices equipped with these novel carbon nanotubes are expected to have superior desalination, disinfection, and filtration properties. The embedded nanoparticles are released from the zeolite matrix by exchange with other cations in solution. Nanoparticles have two significant properties that make them particularly attractive as sorbents. Magnetic nanoparticles are a class of nanoparticle that can be manipulated using magnetic fields.
