Adsorptive Remediation of Pollutants from Wastewater

Abstract

An exponential increase in demand of water, commonly known as green and universal solvent is known to have multiple applications in different sectors including domestic, agricultural, and industries. Industrialization, the “pillar of economic development” has greatly affected our water resources since last decade attributed to an increase in the percentage of grossly polluting industries (GPIs) from 1162 to 2743 units. Water being a necessity of livelihood, it becomes necessary to treat it before discharging. This study incorporates the different techniques available to wastewater treatment and primarily focuses on the adsorption remediation as this is an easy/simple and cost-effective technique for wastewater treatment. Emphasis will also be given on the different types of adsorptive material available and the parameters affecting adsorption technique such amount of adsorptive material, time, pH, etc. to improve the water quality and study of different mathematical models to get the better understanding of the technique. Lastly, the chapter will be concluded by highlighting the major research gap and future scope of adopting the present technique and modification needed to improve its performance without compromising much with the production cost. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
