ABSTRACT

This chapter addresses harmful effects due to the excessive presence of phosphorus and discusses the available treatment technologies for its removal along with its recovery and recycling. It aims to revolve around the green and eco-friendly methods adopted for removal of phosphorus from wastewater. Substances and elements such as ammonia, nitrogen, phosphorus, and so on are widely found in effluents from domestic sewage and municipal wastes. Most importantly, excessive availability of phosphorus disturbs the ecological balance by triggering the eutrophication of water bodies, thereby resulting in the uncontrolled growth of aquatic plants and algae. Adsorbents such as bentonite, zeolite, red mud, lanthanum hydroxide, and iron-related adsorbents have been successfully employed for the removal of phosphorus by the adsorption technique. Chemisorption was found to be the dominating driving force while eliminating phosphorus from waste water. The eradication and recycling of phosphorus can be increased by the adoption of green and environmental friendly materials.
