Application of Biochar for Wastewater Treatment and Recovery of Value Added Products

Abstract

Over the previous decades, limitations in water resources has changed the human perspectives of waste water i.e., conversion of waste to value-added resource. Utilization of waste-water will not only mitigate scarcity of water, but can also help in recovering nutrients and energy. Furthermore, scientists have investigated biochar-application for the removal ofvarious contaminants from aqueous wastes. Biochar has numerous advantages in relation to: cost, pollutant adsorption efficiency and nutrient retention endow possibility for valuable resource recovery from biochar, plus being an a new sorbent with a lot of promise, it has shown much more applications such as a variety of sources for the feedstocks, easy to prepare, and a very favorable surface and structural properties. Therefore, studying and considering relationship between resource recoveries from biochar is important to develop the properties of biochar in remediation of environment and the sustainable utilization of waste water. This following reviews provide a schematic overview of the recent advancements in biochar application for recovery of value added products from wastewater treatment, along with different mechanisms of sorption involved Contaminants from wastewater are removed with this method
