THE INFLUENCE OF WETLAND MEDIA IN IMPROVING THE PERFORMANCE OF POLLUTANT REMOVAL DURING WATER TREATMENT: A REVIEW

Biochar is used for water treatment as a low-cost adsorbent with high efficiency. It has a large pore volume and is environmentally friendly. Recently, biochar has been a popular topic in the field of environmental management and wastewater treatment. There has been a rising interest in biochar due to its low-cost production, environmental stability and potential effects on several ecosystem functions. A high number of studies have shed light on the potential use of biochar as a sorbent as well as the application of biochar to adsorb pollutants in wastewater and enhance the efficiency of constructed wetlands. The removal of heavy metals from aqueous solutions was examined and biochar was found to efficiently remove more heavy metal ions from these solutions than activated carbon. This study has shed light on the role of biochar in water treatments and provided an updated review to produce biochar from different biomass feedstock around the world.
