Abstract—Sufficient treatment of leachate is vital before it is
discharged into receiving water bodies. MLS leachate is
characterized as partially stabilized leachate. Therefore,
coagulation is a fair treatment to degrade pollutants in MLS
leachate. The aim of this study was to evaluate the optimum
coagulation conditions of dose and pH of iron chloride for MLS
leachate by using jar test. The influence of iron chloride dose,
resulted in percentage removal of SS (97% at 1500 mg/L), color
(95% at 1500 mg/L), COD (66% at 2000 mg/L) and NH3-N(13%
at 3500 mg/L). While theaffect of pH, SS (94% at pH6),
color(95% at pH6), COD(66% at pH 6) and NH3-N(56% at
pH 6) were observed. Optimum dose and pH at 1500 mg/L and
6 were selected for SS, color and COD.Meanwhile,dose 3500
mg/L and pH 12 were selected for the optimum coagulation
condition for NH3-N removal. Overall, treatment of the MLS
leachate by the coagulation process with addition of IC was
effective for SS, color and COD but weak in reducing NH3-N.
