A research carried out to examine the effectiveness of powder extracted from mature dried Moringa oleifera seeds as a coagulant, which is commonly available in most rural communities of Africa. The results obtained showed that powder from seed kernels of Moringa Oleifera contains coagulating properties at loading doses of 10 g/L and above that have similar effect as the conventional coagulant, alum.
