Effect of coagulation-adsorption pretreatment on ultrafiltration membrane fouling to remove organic matter on leachate
Abstract
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.
