Removal of Pollutants from the Wastewater by Composite Nanofibers

Wastewater may be defined as a combination of liquid or water-carried waste removed from residences institutions and commercial and industrial establishments together with ground water surface water and storms. Water is essential for human survival and well-being so ensuring adequate water resources is critical. However it has been recorded that more than 80 countries around the world are experiencing extreme water shortages with approximately 25% of the population lacking adequate access to fresh water in sufficient quantity and quality. Owing to population growth rapid industrialization and long-term droughts the spread of a wide variety of pollutants in surface water and groundwater has become a critical problem worldwide. Controlling the harmful effects of pollution and improving human living conditions are thus important. Heavy metals inorganic chemicals organic contaminants and a variety of other complex compounds persist in wastewater.
