Abstract

Moringa oleifera, a versatile plant utilized across various domains, shows significant promise as a natural coagulant for water and wastewater treatment. This study reviews the advancements in employing M. oleifera to address the pressing global water contamination crisis, particularly in developing countries where access to clean water is critical. We analyze the effectiveness of M. oleifera in removing turbidity, harmful microorganisms, and contaminants such as heavy metals from diverse water sources. Characterization studies highlight its superior coagulation properties compared to traditional chemical coagulants, revealing a reduction in turbidity by up to 87% and substantial antibacterial activity. Additionally, the plant’s components can be enhanced with materials like sand for improved efficacy. Surveys conducted in rural communities show a gap in awareness regarding M. oleifera’s water purification potential, suggesting the need for educational outreach to promote its use. This review underscores the importance of integrating M. oleifera into water treatment strategies, advocating for its scalability and sourcing sustainability to combat waterborne diseases and improve public health outcomes globally. Continued research and innovation could further enhance its application, positioning M. oleifera as a costeffective and eco-friendly solution in the ongoing battle for safe drinking water.
