| Summary: | This research's main goal is to decrease the concentration of fats and oils, phosphorus, and organic material in the wastewater. This study, therefore, explored the use of activated Moringa oleifera as an alternative adsorbent for decreasing the phosphate concentration and organic material as BOD5 via the adsorption process. A grease trap was used to catch fats and oils, separated into three compartments. The use of these three compartments aimed to improve the efficiency of grease traps. In the meantime, adsorption was used to decrease the concentration of BOD5 and phosphate. moringa oleifera and commercial activated carbon (Powdered Activated Carbon, that produced from carbonaceous raw materials, coconut shell, and wood) were the adsorption media used in this analysis. The findings of this study showed the grease trap capability in which it could remove 89.83% of fats and oils by using three compartments. When considering the optimum condition achieved by using moringa oleifera as the adsorbent, it was found that more than 85% of both BOD5 and phosphate can be removed with an adsorbent height of 15 cm and an adsorption tube diameter of 15 cm. Additionally, Thomas Model was fitted by moringa oleifera and commercial adsorbents to explain the pattern of adsorption of BOD5 and phosphate in wastewater. The results of the model showed a maximum reduction in BOD5 690 mg/g and phosphate 0.215 mg/g by moringa oleivera adsorbents. This research investigated the effectiveness of Moringa oleifera as an adsorbent, cnsidering the basic surface area characteristics, pore diameter, and pore volume of Moringa oleifera as an adsorbent.
