Bio Nanotechnological Intervention: A Sustainable Alternative to Treat Dye Bearing Waste Waters

Abstract

Waste water treatment issues have been a growing problems these days. It has become stringently important to treat waste water prior its release into adjoining surface water bodies. In recent past, bio nanotechnological solutions have proved to be of paramount importance in circumventing the issues associated with dye bearing waste waters. Nanoparticles have a great potential to be used in waste water treatment. Its unique characteristic of having high surface area can be used efficiently for removing toxic metal ions, disease causing microbes, organic and inorganic solutes from water. Various classes of nanomaterials have been efficiently utilized for above cited facts including treatment of dye bearing waste water released from textile industries like metal-containing nanoparticles, carbonaceous nanomaterials, zeolites and dendrimers. The paper presents a comprehensive review of recent advances on different nanomaterial based mitigation strategies. Special emphasis has been given to green synthesis of nanoparticles aimed to address problems associated with textile effluents through nano bioremediation.
