Abstract: The use of alum dose in drinking water treatment plant has harmful effects on human health, on the one hand and on the other hand, a process that alum coagulant dose used in drinking water treatment plant with a high processing cost. In this study, the use of Aleskan Compact Drinking Water Treatment Plant in Ad Diwaniyah city in Iraq for the purpose of conducting experiments adding Moringa Oleifera seed and leaves (as a natural coagulant) instead of alum dose to treat drinking water to remove turbidity and heavy metals from surface water. The study samples were taken from the Ad Diwaniyah River, as well as water samples were taken from the all basins of Aleskan Compact Drinking Water Treatment Plant in Ad Diwaniyah city. Experimental runs were carried out for three hours per run over an eight month period with turbidities ranging from 20 to 1000 NTU. Proven results of the study that by using natural coagulant Moringa oleifera seed and leaves ( which is a natural trees available in the province of Ad Diwaniyah In Iraq) instead of alum does not carry any impact on human health , and has a high efficiency up to 99% in the removal of turbidity from surface water and up to 98% in the removal of heavy metals from surface water. The turbidities and heavy metal during most of the test runs satisfied the WHO for Potable Water Supplies.
