Article Synopsis
- The paper reviews various physico-chemical techniques for treating landfill leachate, focusing on methods like coagulation-flocculation, chemical precipitation, ammonium stripping, membrane filtration, and adsorption.
- It evaluates the advantages and limitations of these techniques by comparing operating conditions, treatment efficiencies, and characteristics of the leachate, revealing that no single method is universally effective for removing persistent compounds.
- Combined treatments, particularly using membrane filtration with biological methods, have shown high effectiveness in removing chemical oxygen demand (COD) and ammonium nitrogen (NH3-N), emphasizing the need to select methods based on leachate characteristics, technical feasibility, costs, and regulatory requirements.
