| Abstract: | A laboratory study using a bench scale model of two units operation involving coagulation process with Moringa oleifera seeds extract as a coagulant and filtration process using hollow fibre microfiltration membrane, was adopted to treat Air
Hitam Sanitary Landfill leachate in Puchong, Malaysia. The performance of the microfiltration membrane in pretreated sanitary
landfill leachate treatment was investigated through a continuous process. The leachate sample was passed through conventional
coagulation process before being filtered through a hollow fibre microfiltration membrane of 0.1 μm surface pores. The hollow
fibre microfiltration membrane decreased the turbidity, colour, total suspended solids, total dissolved solids and volatile
suspended solids in the leachate by 98.30, 90.30, 99.63, 14.71 and 20%, respectively. The results showed that microfiltration
is capable of removing high percentage of solids from leachate and might be considered as a polishing stage after on-site
biological treatment for sanitary landfill leachate. |
