ABSTRACT
Provision of clean water is a major challenge in developing countries due to increasing cost of chemicals used in water treatment. The search for sustainable and affordable natural plant material has been a subject of research for decades. This study aims to investigate the efficiency of Moringa oleifera as natural coagulant in domestic water treatment. Raw water sample was collected and analysed before and after treatment with the seeds powder at varying coagulant dosages. Maximum removal of turbidity and colour was observed at an optimum coagulant dose of 750 mg/l corresponding to removal efficiencies of 93% and 98% respectively. The quality of water improved as coagulant dose increased. The addition of Moringa oleifera to water did not cause any undesirable change in the water quality. This research recommends that Moringa oleifera should be grown locally and adopted as a natural coagulant for domestic water treatment in developing countries.
