Water is a resource that is essential for life and is required by almost every living organism. This resource is, however, becoming very limited in its pure state due to the many anthropogenic means of contamination which arise from the different industrial advancements made over the years. Water pollution is a serious problem for the entire world and contributed to negative environmental and human health impacts. Drinking water needs to be treated in order to remove impurities and bacteria to meet the quality guidelines which satisfy 5 nephelometric turbidity units (NTU) for drinking water requirement according to the World Health Organization. Plants are rich in secondary metabolites and are being used for the treatment of various ailments. Moringa oleifera (MO) is a multipurpose tree with considerable potential and its cultivation is currently being actively promoted in many developing countries. Seeds of this tropical tree contain water-soluble, positively charged proteins that act as an effective coagulant for water and wastewater treatment. The coagulant particles and properties which have been confirmed in laboratory studies due to this coagulating properties that have been used for various aspects of water treatment such as turbidity, alkalinity, total dissolved solids and hardness. However, its bio-sorption behavior for the removal of toxic metals from water bodies has not been given adequate attention. The seeds are neither harmful to humans nor animals. It is quite efficient in reducing microorganisms’ presence in raw water. Thus, water treated using such natural coagulant is more recommendable to use compared to one treated with alum. Treating water at different dosage is recommended and yielded a positive outcome. This is one of the merits of Moringa seeds over alum. The seeds are environmentally friendly because they do not further deteriorate the environment. Also, due to its availability and maximum effluent removal from both domestic and synthetic wastewater, the application of the seeds in wastewater treatment is undeniable intrinsically
