Sustainable sewage water treatment is becoming increasingly important in the current global scenario of water scarcity and environmental degradation. One promising technique in natural plant coagulation that has gained attention in recent years is the use of Moringa oleifera for wastewater treatment. The statement of my study was to investigate the effectiveness of Moringa oleifera in reducing turbidity and impurities in sewage water using a jar test as a qualitative technique in coagulant and flocculation, analyze physical and chemical parameters for raw water and treated water, the optimum dose shown to treat water was 0.4g/1000ml. The obtained result indicated that Moringa oleifera is effective in reducing turbidity respectively by 92%, COD by 88%, Total solids by 96%, Chloride by 75%, Total hardness by 74%, Inorganic phosphorous by 68%, and BOD found. This study concludes that the use of Moringa oleifera for sustainable sewage water treatment is a promising green technique that has the potential to contribute more benefit to people, moringa oleifera as NPC for water treatment can lead to significant improvements in the quality of water and the health of societies while also promoting sustainability and environmental harmony.
