Surface water is one of the major source for domestic water in many developing countries and due to the great exposure of such water to contamination, treatment is necessary before use. Physical as well as chemical treatment can be used depending on the type of pollutant to be removed .Aluminum sulfate (Alum) is commonly used worldwide as a coagulant. However, it has many side effects to human health and environment for example it is known to cause Alzheimer’s disease, it produce large sludge volume which stays in the environment for long time,M.oleifera seed extra is a biocoagulant,non toxic, locally producible and friendly to the environment. The use of M.Oleifera seed extraction including Lindi salt extraction. Water extraction, consecutive extraction and phytofloc extraction. Indi salt extraction performed better compared to the rest and is easily obtained. The study revealed that M.Oleifera seed extract can be stored for eight weeks in ambient temperature(25C) and at refrigeration temperature(8C) without affecting the water flocculation efficiency and optimum dosage and flocculation efficiency.M.Oleifera seed extract can be processed at family level and at large scale therefore it can be used to supplement Aluminum sulfate if not to substitute it. The adoption of M.Oleifera seed extract as water coagulation may enable many people in rural and urban dwelling to access clean drinking water.
