Hydrogels for Wastewater Treatment: A Review

Amar Nath

Abstract: The requirement of fresh drinking water increases day by day rapidly, because of industrialization the rising the industrial discharge which passed directly into the river which caused enhanced the contaminated water in water reservoir. The deficiency of pure water can be maintained by the purification of river and other reservoir. There are going to search effective, sustainable and economical technologies that applicable for the treatment of water. The hydrogel polymeric materials that have three-dimensional hydrophilic structure and also amazing swelling capacity that developed as capable substance shows waste water treatment. Due to the availability of flexibility structural behavior, wide surface area and versatility in functional group enhanced adsorption and elimination of toxic metals, organic dyes, pharmaceuticals and other evolving contaminants. For this purpose, various natural and artificial polymeric hydrogels, hydrogels with nanocomposite have been industrialized to facilitate adsorption capacity, selectivity towards pollutants and revival capacities. This review illustrates the ethics of polymeric hydrogel for wastewater treatment, pollutant removal process, current developments, limitations, forthcoming perceptions, developing hydrogel with modern treatment technologies.

Keywords: Waste water, Polymeric hydrogel, nanocomposite, pollutants, swelling capacity
