Abstract

Loading of water with multifarious pollutants has dwindled the availability of quality fresh water and put questions on reliability and efficacy of conventional water treatment technologies. Also the quest for developing robust and cost-effective methods with minimum impact on environment had driven the focus of researchers and technologists on new technological developments. Nanotechnology – better referred as Aqua-nanotechnology in this regard provides scientists a new dimension to deal this big problem with small particles having application in 1) water treatment, 2) remediation, and 3) pollution prevention. This chapter will focus on fabrication and use of advance nanomaterials categorized as nanoadsorbents and nanoatalysts for these three main areas. A range of materials exploited in this regard are single and mixed metal oxides and their composites with polymer, clay, carbon based materials etc. while keeping focus on technological developments taken place over the period in regard with treating water and waste water.

Aqua-Nanotechnology

“Aqua-nanotechnology” has now been recognized as a branch of nanotechnology that deals with the application of nanomaterials for 1) water treatment, 2) remediation and 3) pollution prevention (Tratnyek et al., 2006). Nanotechnology-enabled treatment of water and wastewater provides the much needed technological revolution desired to facilitate the removal of a large range of contaminants in an easy, timely and affordable manner with much-improved treatment efficiency (Qu et al., 2013). This chapter addresses the development and implication of nanomaterials like metal and mixed metal oxides, polymer composites, clay composites, carbon-based composites etc. that ameliorated the water quality by promoting sustainable water management.
