Abstract
The unprecedented incidence of rising industrialization, population concentration, and mismanagement of water resources has contributed to water scarcity and pollution in many countries. Water pollution poses a great health threat to humans and animals, as well as the ecosystem. Researchers around the globe have brought to light different methods of using natural Moringa oleifera seed in water and wastewater treatment through coagulation, flocculation, sedimentation, biosorption, photocatalysis, and adsorption, among others. These trends toward using natural products for water purification can help avoid the side effects of synthetic chemicals such as alum employed in wastewater decontamination and minimize the cost of treatment. This chapter seeks to comb through the literature and identify the available trends in using Moringa seed to treat water and wastewater, as well as highlight their prospects and challenges for developing countries.
