Nano Technology and Waste Water Treatment- Opportunities and Challenges

Abstract

Water is most important need of human life. Water contamination is among one of the major issues faced by the whole world today. Water contamination not only effect environment and human health, but it also has greater effects on economic and social costs. There are numerous ways that are used commercially as well as non- commercially to solve this problem which is advancing day by day due to unprecedented technological growth. Nanotechnology has great prospective in advancement of waste water purification to get better treatment efficiency by which humans can be provided the quality water supply. The high surface areas of nanomaterials, upgraded membrane technologies and the catalytic properties of some nanomaterials have potential for removing toxic metal ions, disease causing microbes, inorganic and organic solutes from waste water. This study aims to include modern development in nanotechnology for wastewater treatment. It covers details about various nanotechniques like Nanosensors, Nanosorbents, Nanofilteration and Reverse Osmosis etc. The Positive and negative effects of Nanotechnology have also been discussed. Nanotechnology has led to various efficient ways for treatment of waste water in a more precise and accurate way on both small and large scale. Nanotechnology is able to treat water for daily use and industrial purposes which is the high-priority of eco-friendly system.
