Effectiveness of Using Milled Moringa Oleifera Seeds as a Natural Coagulant in Waste Water Treatment

Abstract

This research was conducted with the aim of investigating the performance of milled moringa oleifera seeds as a natural coagulant in waste water treatment. Operating parameters such as pH, temperature and total suspended solids were tested at different water turbidities. Elemental analysis of raw Moringa Oleifera seeds showed that iron was the predominant element. The percentage turbidity removal for Moringa Oleifera seeds on low, medium and high turbidities were 84.6%, 94.8%, and 72% respectively. Generally, the turbidity removal increased with an increase in Moringa Oleifera dosage. Lower speeds promote the floc formation rate on low turbid water and the results also revealed that the dosage of Moringa Oleifera does not affect the pH of water as the final pH for all the experiments was within the required standard of 6.5-9.5. Moringa oleifera seeds showed a greater potential to be applied as a natural coagulant.
