In order to ensure safe and adequate water availability, many communities have engaged in water and wastewater treatment. Some of chemicals used for water treatment are less effective due to high costs and side effects making use of natural coagulants an ideal option. This study was conducted to compare effectiveness of Moringa Oleifera (MO) seeds powder as a natural coagulant with Aluminium sulfate (Alum) as a chemical coagulant. The effectiveness and efficiency of MO against Alum was established by using jar test method before and after groundwater treatment. By using concentrations of MO and Alum ranging between 50 to 200 mg/L, a significant reduction of pH, EC, TDS, turbidity, total hardness, chloride content, total alkalinity and total coliforms was observed while beyond it efficiency was impaired. MO treated samples showed promising quality than Alum solution that significantly lowered the pH of water. The established optimal MO seed powder dose for turbidity treatment was 200 mg/L.
