Currently industries find it difficult to go on with the existing technology due to higher costs and increasing environmental concerns. As a result, various industries and other interest groups have hugely invested in nanotechnology researches as this technology is predicted to be a better alternative to the existing chemical treatments. One of the major issues is that the world has been facing severe water pollution and paucity issues over the last two decades. The existing chemical treatments for water purification have been outdated due to their complexity and higher cost. This paper identifies that nanotechnology is a better alternative to the existing chemical treatments as this technology is more cost efficient and eco-friendly. Contents Abstract Introduction 1 1.
