ADSORPTION TREATMENT OF LANDFILL USING LOW COST ADSORBENT- REVIEW

The most cost-effective, popular, and favored form of solid waste management is landfilling. Despite the many benefits of landfilling, the production of highly contaminated leachate is a significant disadvantage. Mismanagement of leachate can result in a variety of health risks, beginning with contamination of groundwater and surface water. Landfill leachate has been treated in a variety of ways, ranging from biological to chemical to a combination of both. However, new research has discovered that activated carbon adsorption has special features that can remove contaminants from landfill leachate. Recognized as the most acceptable method for removing refractory compounds in aqueous and actual effluent due to its ability in terms of physical and chemical sorption, as the most anticipated treatment method that has been studied using a wide range of precursors derived from natural resources, synthesized materials, and agricultural wastes, as the most anticipated treatment method that has been studied using a wide range of precursors derived from natural resources, synthesized materials, and agricultural wastes. The purpose of this research is to examine the various agricultural wastes that are utilized as precursors in the production of activated carbon for the treatment of landfill leachate. In addition, the main breakthrough of activated carbons adsorption with an emphasis on low-cost precursors, implementation obstacles, and future expectations will be highlighted.
