摘要：

Commercial/ conventional coagulant was used for the removal of COD and turbidity from landfill leachate containing COD 2451 mg/L. Coagulation studies were performed with lime and alum by varying parameters such as pH and coagulant dose. The experimental study shows that coagulation with calcium hydroxide and alum can remove up to 69% and 54% COD from the leachate. The optimum process variables of this coagulation study were found for calcium hydroxide and alum as pH 8 and 6; and coagulant dosage 25 g/L and 15 g/L, respectively.
