Abstract
Introduction: Dragon fruit is the tropical fruit belongs to the Cactaceae family (cactus species), known as pitaya or pitahaya. The peel of dragon fruit iis often regarded as a waste that has the potential to be a coagulant for physical-chemical of wastewater. Landfill leachate is a complicated wstewater with high concentration of pollutants and has been identified as potential sources of ground and surface waters contamination. Two most common type of dragon fruit are Hylocereus polyrhizus-purple pinWred fleshed (DFPP) and Hylocereus undarus-white fleshed (DFPW). Objectives: The main aims of this study is to determine the potential of both DFPP and DFPW in the removal of turbidity, total dissolved solids (TDS) and total suspended solids (TSS) from landfill leachate. Methodology: DFPP and DFPW were prepared in the lab and were applied to the leachate at several dosages using standard jar test method and sedimentation times were recorded. Physicochemical parameters i.e. turbidity, TDS and TSS were measured in lab using HACH Turbidimeter 2100N, portable TDS meter (Model HACH) and vacuum filter apparatus respectively. Results and Discussion: DFPP was able to remove 60% of turbidity and 23% of TSS at an optimum dosage of 50 mg/L. In terms of TDS removal efficiency, 65% was able to be removed h m raw leachate by using 90 mg/L of DFPP. Results showed that when using DFPW at an optimum dosage of 90 mg/L, removal percentage of 67%, 69% and 36% for turbidity, TDS and TSS respectively, can be reached. As the sedimentation time increases, the removal percentage also increased for all three parameters. Conclusion: Results indicated that both DFP have coagulant capabilities but DFPP were bener in removing turbidity and TDS compared to DFPW. Yet, in terms of TSS removal, DFPW was a better coagulant than DFPP. For DFPP, between turbidity and TDS, DFPP was better in removing turbidity than TDS. Thus, it can be concluded that dragon fruit has the potential to be used as a natural coagulant for leachate treatment. Keywords: Dragon fruit peel, leachate, turbidity, TDS, TSS, coagulationflocculation
