This study employed an innovative electrocoagulation method to treat landfill leachate, utilizing uniquely designed aluminum electrodes. The investigation focused on the effects of various parameters on treatment efficiency, including initial pH, current density, NaCl concentration, and stirring rate. Results demonstrated that the initial COD concentration of 9600 mg/L was reduced to 282 mg/L at a pH of 5, 40 mA/cm2, 0.1 M NaCl concentration, and stirring rate of 60 rpm with the removal efficiency of 97%, meeting direct discharge limits. Additionally, successful removal of phosphorus and nitrogen was achieved, underscoring the comprehensive treatment capabilities of electrocoagulation. Furthermore, electrocoagulation sludge was repurposed for geopolymer production, highlighting the potential for sustainable waste management practices. These findings offer valuable insights for optimizing landfill leachate treatment strategies while promoting environmental sustainability and presenting an excellent opportunity for industrial symbiosis.HighlightsAn innovative electrocoagulation method was employed for the treatment of landfill leachate, utilizing uniquely designed aluminum electrodes.Successful removal of COD, phosphorus, and nitrogen was a noteworthy achievement that meets the criteria for direct discharge into water bodies.Treatment efficiency was optimized by examining the effects of parameters such as initial pH, current density, NaCl concentration, and stirring rate.The utilization of electrocoagulation sludge as raw material for geopolymer production represents a sustainable approach to waste management and resource utilization.
