摘要

Water has been the most valuable and plentiful natural resource on earth. This abundant resource is under an alarming threat of water scarcity due to the continuously growing undesirable human activities (such as industrial, agricultural and urban domestic practices, dumping, atmospheric deposition, etc.). Water scarcity is increasingly becoming the primary risk to food security, natural ecosystems and human health. The world population is increasing at a brisk pace and expected to reach 9.5 billion by 2050. Therefore, to meet the livelihood demands of the increasing population, industrialization and agriculture growth is inevitable. As a consequence, more industrial, agricultural and domestic sewage will be produced. Sewage released from industrial and agricultural practices contains dangerous chemical contaminants. While domestic sewage contains pathogens. All these toxic pollutants would lead to a catastrophic situation, if proper water management measures are not taken both adminstravtively and scientifically. Scientifically various materials (fly ash, natural phosphate, bentonite, activated carbon, cyclodextrine, few novel polymeric materials, etc.,) have been used to control water contamination; however, their contaminant removal efficiencies were not enough to be considered for large scale applications. With the emergence and progress of electrospinning, which is a nanofiber producing technique; researchers are now more focused on studying electrospinning technique for producing nanofibers membranes. Due to the potential uses of nanofibers in almost all areas of science, engineering and technology, they are gaining the reputation of one of the greatest investigative subjects for academia and principal business elements for industries. This chapter will take an overview of the progress made by electrospinning technique, nanofibers surface modification and the potential of these modified nanofibers in the treatment of wastewaters from industries, agricultural and domestic waste.
