Surface water clarification using M. oleifera seeds.


Abdullah, Abdul Ghani Liew and Megat Mohd Noor, Megat Johari and Muyubi, Suleyman Aremu and Fugara, A.M.S. and Muhammed, T.A. and Iyuke, S.E. (2006) Surface water clarification using M. oleifera seeds. International Journal of Environmental Studies, 63 (2). pp. 211-219. ISSN 0020-7233


Turbid surface water was treated using a pilot scale water treatment plant comprising coagulation, flocculation, sedimentation and rapid gravity filtration, using Moringa oleifera seeds/alum as coagulants. Turbidity removal of M. oleifera, alum, and the mixture of both M. oleifera/alum were compared, and results obtained were 7.2, 4.2 and 3.2 NTU, respectively. The turbidity achieved using M. oleifera/alum mixture and alum were less than the required standard of 5 NTU, while M. oleifera/alum mixture recorded the least turbidity value (3.2 NTU) with removal efficiency of 99%. The natural alkalinity of the water did not vary during the treatment processes. Therefore M. oleifera/alum mixture could be considered as a suitable alternative for partial replacement of alum as coagulant in surface water treatment, which is an added advantage since M. oleifera is a natural product with less or no side effects as compared to alum as a chemical agent.
