Leachate is created while water penetrates through the waste in a landfill, carrying some forms of pollutants. The goal of this chapter is the introduction to leachate treatment. Biological, physical, and chemical treatments of leachate are the most common methods. The biological techniques in leachate treatment are studied. The physical-chemical ways for landfill leachate treatment like chemical precipitation, chemical oxidation, coagulation–flocculation, membrane filtration, ion exchange, adsorption and electrochemical treatment are studied. The landfill leachate properties, technical applicability and constraints, effluent discharge alternatives, cost-effectiveness, regulatory requirements and environmental impact are important factors for selection of the most suitable treatment technique for landfill leachate treatment.
