Use of Aloe Vera and Moringa Oleifera as Biocoagulant in Palm Oil Industry

Abstract

Production activities in the palm oil industry generate waste, which is commonly called as Palm Oil Mill Effluent (POME). POME is a thick brownish viscous liquid waste, slurry, high in colloidal suspension and has an unpleasant odor. One of the processing units on its waste water treatment plant is coagulation-flocculation using synthetic coagulant. The improperly dosage causes fluctuative effluent quality of the waste water treatment plant. Therefore, the researcher had analyze the use of Aloe vera and Moringa seeds as biocoagulant on oil industry’s waste water treatment plant. Based on the results of the test, the optimum concentration of Aloe vera 60 mL/L proved the removal efficiency of COD was 77,51%; TSS was 45,29%; and turbidity was 79,51%. Moreover, the optimum concentration of moringa seeds 12 mL/L proved the removal efficiency of COD was 70,67%; TSS was 40,52%; and turbidity was 75,8%. Whereas, the optimum concentration of mixed Aloe vera and moringa seeds is 32 mL/L proved the removal efficiency of COD was 76,83%; TSS was 40,3%; and turbidity was 74,57%.
