A Review on Various Bio-Resources as a Tool to Reduce Water Pollution Via Eco-Friendly Adsorption Technology

Pollution of water bodies is a raising concern in today’s world. Water pollution occurs when harmful compounds enter water bodies and lowers the water quality. It is necessary to treat wastewater before its final disposal into aquatic bodies and environment. Among all the conventional water treatment techniques, adsorption technology attracted much attention owing to its simplicity and eco-friendly nature. Several studies were reported with the application of different kinds of adsorbents in the treatment of both organic and inorganic pollutants in wastewater. However, demand for the development of more suitable adsorbent with selective pollutant removal capacity and good economic feasibility is still rising. Therefore, this review aims to provide a detailed review about the adsorption technology and its mechanisms in pollutant removal process. The adsorption ability of certain important adsorbents were discussed along with future perspectives. Effective, economical, and environmentally friendly wastewater management should be the ultimate objective of any wastewater treatment process. Keeping that in view, this review article highlighted the importance of wastewater management and treatment via adsorption technology.
