Background and Aims: One of the main issue facing cities nowadays is the management and control of landfill leachate. In order to reduce the releasing of contaminants from landfills into environments, the removal of contaminants is necessary. The aim of this study was to determine the efficiency of Aluminum Sulfate(alum) in the removal of COD, TSS, turbidity and color from leachate produced from Sanandaj’s landfill.
Materials and Methods: In this study, the leachate were guided into a pond. Samples were obtained from this pond in two-week intervals for six. Experimental samples were transported to the laboratory and stored at 4 °C until testing.
Results: The results showed that the highest efficiency of alum for removing COD(64% removal) was achieved at pH=8.5 and 9000(mg/l) concentration. Also results showed that the highest efficiency of alum for removing TSS was achieved at pH=7 and 9500(mg/l) concentration and Turbidity and Color was achieved at pH=8.5 and 8500(mg/l) concentration.
Conclusion:With regards to the short time, low materials, and less skill for adaptation, the use of alum system is recommended to treat the landfill leachate..
