APPLICATION OF NANOPARTICLES IN WASTEWATER TREATMENTT. ESAKKIMUTHU, D. SIVAKUMAR AND S. AKILAAbstract Nanotechnology is a branch of study, which deals with the molecular level re-arrangement of atoms. This is becoming the active and advanced topic nowadays. Particles whose size lower than 100 nanometer are involved. Although the particles which have size lesser than 100 nm are considered as nanoparticles, nowadays, people use the word nano for tiny particles. The word nano is used in more areas in modern world, e.g., Tata nano car. Nanotechnology has its own applications in many branches of science and engineering such as medicine, biotechnology, food and beverages, aerospace, chemical, construction, environmental, consumer goods such as fabrics, textiles, sports, cosmetics, military, fire protection etc. In particular, the application of nanotechnology in the field of environmental engineering such as water treatment is wider. Various environmental problems can be addressed and future problems can be averted by using the various concepts in nanotechnology. Many researches are going on in the field of nanotechnology for solving different environmental problems such as water, and wastewater pollution. This paper mainly focuses on the various types of nanomaterials in the field of waste water treatment and along with the future prospective.
