Abstract

The existence of humic substances is the key factor for antagonistic coloration of stabilized landfill leachate, which is a remarkable pollutant parameter. To examine the performance of natural starch from oil palm trunk (OPTS) like a coagulant is the focus of the current study, for the removal of color through coagulation-flocculation followed by membrane filtration. A series of jar tests were conducted for two different landfill sites through optimizing the dosage and pH followed by membrane filtration. The separation technique of starch from palm oil biomass, its morphology by scanning electron microscopy (SEM) as well as membrane filtration were discussed. Experimental results showed that the combination of coagulation-flocculation with OPTS as a novel natural coagulant and membrane filtration (CMF) yielded 81% and 82% of color removal for Pulau Burung and Alor Pongsu leachate respectively at optimum pH 6.0, a dosage of coagulant 1500 mg/L and 29 °C temperature within a green approach than other conventional methods. FTIR spectrum peaks of leachate after CMF indicates the absence of certain groups of different wavelengths (wavelength 3100 cm-1-3500 cm-1, 1535 cm-1, and 1900 cm-1 to 2100 cm-1). The findings revealed that this CMF method can be a novel and sustainable alternative of harmful chemical coagulants for the removal of color from stabilized leachate.
