Magnetic treatment is an alternative simple approach by which landfill leachate treatment could be improved. The purpose of landfill leachate treatment is to remove the Suspended Solids, Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD). Based on experiment by using circulation flowing system with a magnetic strength of 0.55 T, it was shown that the leachate quality could be improved. The results showed that the removal percentages of above 60% for SS, COD and BOD. This study concluded that magnetic technology has the potential to be used for improving the removal of SS and organic concentration from landfill leachate.
