The efficiency of Moringa oleifera seed powder as a coagulant for the removal/reduction of turbidity from surface water was studied. Batch experiments were carried out to study the effect of various process parameters such as pH, coagulant dose, and settling time on turbidity percentage removal efficiency and the optimum condition for maximum turbidity removal was identified. The kinetics study was carried out to determine parameters such as rate constant and rate order. The results revealed that treating highly turbid and contaminated raw water with Moringa oleifera seed powder is viable for household/community use. The optimum dosage, pH and time recorded were 400g/ml, 10 and 25minutes, respectively with percentage removal efficiency of 92.97%. The kinetics study showed that the coagulation was second order.
