Description
Summary:Electrocoagulation has been emerging as a promising future and offers various advantages in dealing with highly recalcitrant organic wastewater. For the past years, electrocoagulation managed to deal with different types of water and wastewater pollutant removal efficiently. Compared to previous conventional method of coagulation/flocculation, electrocoagulation is highly rated and improves the removal efficiency, especially for a multitude of recalcitrant pollutants. Landfill leachate is considered as one of the highly recalcitrant organic wastewater that results from the degradation of complex organic and inorganic material, which requires serious attention for treatment before being released back to the environment. In this review, a comprehensive discussion was carried out on the theory, operating parameters, intensification, and modelling of electro-coagulation, especially in treating landfill leachate. The recent development of landfill leachate studies is explored in this paper, including the theory and fundamentals of solid waste management. This review provides an extensive cover to the theory, factors, modelling, intensification, and advanced electrocoagulation treatment for landfill leachate treatment.
