Waste management issues have always been a challenging task to most developing countries. Introducing COLUFNAS geotextile as a new adsorbent material in the waste landfill was an alternative way to reduce the amount of chemicals used for leachate treatment. The laboratory work was carried out using geotextile fabric consisted of cylindrical luffa sponge fiber, granular activated charcoal and coconut husk that were fitted into PVC pipes. The filtration was regulated at contact time of 30 minutes and 1 hour treatment. The experimental results showed that the geotextile efficiency exhibited low total suspended solids (TSS) removal, valued 18.74%, 32.27% for turbidity, 49.71% for biological oxygen demand (BOD5), 10% for chemical oxygen demand (COD), 23.61% for ammoniacal nitrogen and 16% for Total Kjeldahl Nitrogen (TKN) in 30 minutes treatment. Alkalinity was increased as the pH value changes from 5.1 to 5.4 after treatment. This study demonstrated that COLUFNAS is applicable for improving the leachate quality.
