Fouling is something that caused the limits toward the performance of ultrafiltration membranes (UF). The presence of organic matter in leachate water becomes the main cause of membrane fouling. Pre-treated of coagulation-adsorption becomes a solution in reducing fouling and improving UF membrane performances. The objective of this study was to investigate the effect of coagulation-adsorption pre-treatment on the removal of organic matter on leachate and to analyze the most appropriate fouling model to illustrate the hybrid coagulation-adsorption and UF membrane process. The coagulation process was carried out in the optimum condition with pH: 9 and 6g/L with Al2(SO4)3.18H2O, then in coagulation-adsorption process using equilibrium contact time for 60 min with variation of adsorbent dose (0,4;0,5; 0,6;0,7;0,8 and 0,9g/L) and then it was filtered using UF membrane for 60 min with pressure of 1 bar. The Modified Fouling Index (MFI) is an appropriate model to illustrate the formation of fouling in the hybrid coagulation-adsorption and UF membrane processes in the leaching of organic matter in leachate.
