Abstract
Stabilized landfill leachate often contains higher organic fractions than the young one. The organics require several sequential treatments to render the leachate parameters concentrations to permissible discharge limits before being discharged to receiving water. This study focused on the application of Zinc Sulphate (ZnSO4) as coagulant agent followed with microfiltration of 0.45 ?m pore size under different condition of landfill leachates. The results indicated that the sludge volume index (SVI), soluble COD and turbidity concentrations were inter-related to each other when compared under different ZnSO4 dosages. However, that was not the case when correlation between stabilized and young leachate were compared side by side. To conform the finding, one-way analysis of variance (ANOVA) was conducted and the results were further explained by the adequacy and significant of confidence interval. Finally, it was proven that, soluble and particulate COD had significant CI of 95% applicable for stabilized leachate alone. � Published under licence by IOP Publishing Ltd.
