This study attempts to determine the effectivity of Moringa oleifera (MO) leaves as a natural coagulant. Specifically, the study aims to determine the turbidity level of the water that is treated by Moringa oleifera leaves and determine the quantity of MO leaves that will be used to remove turbidity. The researchers predicted that MO leaves are effective coagulant in reducing the turbidity level of the water. In addition, MO leaves can completely absorb turbidity in water. Sythetic turbid water was prepared from solid Kaolin powder. MO leaves were oven-dried until excess water was removed afterwards; it was activated by soaking in NaCl solution. Coagulation efficiency test was performed in two batches: (1) using activated MO leaves; and (2) using non-activated MO leaves. The Nephelometric Turbidity Unit (NTU) was identified using Merck SQ Method 113.Based on the result of the testing of Turbidity levels of the samples sent to SGS, the MO leaves were not able to absorb the turbidity of the sample water hence it worsen the water turbidity as the chlorophyll combines with the solutions. Further test must be employed to determine the complete absorptive capacity of the Moringa oleifera leaves.
