| Abstract | This research aimed to study the performance evaluation of synthetic and commercialcoagulants for landfill leachate treatment using the coagulation process. The factors studiedincluded the type of coagulant. The effects of different coagulant concentrations and pH onthe efficiency of landfill leachate treatment using Alum, FeCl3, and a synthetic coagulant werestudied. Coagulant concentrations of 1, 3, 5, and 10 g/L were investigated at pH 4, 5, 6, 7, 8,and 9, respectively, using a Jar Test stirring method with a rapid stirring speed of 150 rpm for3 minutes and a slow stirring speed of 60 rpm for 30 minutes, with a sedimentation time of 150minutes. The results demonstrate that Alum was most effective at turbidity removal at pH 7and 10 g/L, achieving 96.17 ± 0.17 NTU (78.53%). The synthetic coagulant was most effectivefor COD removal at pH 7 and 10 g/L, achieving 7,686.76 ± 11.55 mg/L (79.30%). FeCl3 wasmost effective at color removal at pH 6 at a concentration of 10 g/L achieving 875.73 ± 0.01ADMI (77.72%). The synthetic coagulant; at pH 7 (10 g/L) removed turbidity, color, and CODby 78.83 ± 1.44 NTU (42.52%), 641.69 ± 0.03 ADMI (62.98%), and 7,686.76 ± 11.55 mg/L(79.30%), respectively. Compared with commercial coagulants, the synthetic coagulant derivedfrom fly ash, a waste from the power generation industry, demonstrated potential as a substitute.This approach reduces waste and provides beneficial application in landfill leachate treatment,contributing to sustainable waste management. |
