Waste Water Reclamation and Reuse in Yenegoa Using Activated Carbon and Zero B M. J. Ayotamuno, O. M. Olatunji and A.J. Akor Department of Agricultural and Environmental Engineering, Rivers State University of Science And Technology, P.M.B 5080, Port Harcourt Abstract In this study, waste water reclamation and reuse was carried out in Yenegoa Metropolis using activated carbon and Zero B methods. Polluted waste water was obtained from Yenagoa waterside, and characterized and treated using activated carbon by column adsorption and Zero-B method separately to ascertain its potentials for reclamation and reuse. The pH, turbidity, total suspended solid (TSS) and Biochemical Oxygen Demand (BOD) test was carried out on untreated and treated waste water. From the results obtained, the untreated waste water has pH 6.4, turbidity = 38.0mg/6, TSS=66.0mg/L and BOD = 14.2mg/L while the values of lead, zinc, copper and chromium present were 0.03mg/L, 0.04mg/L, 0.04mg/L and 0.03mg/L respectively. Similarly the values of treated waste water using activated carbon were 7.2, 1.9mg/L, 9.01mg/L and 4.6mg/L for pH, turbidity, TSS and BOD. While 6.99mg/L, 1.69mg/L, 8.7mg/L and 4.2mg/L were obtained for pH, turbidity, TSS and BOD using Zero-B. The treated waste water values of lead, zinc, copper and chromium have no significant change with the untreated waste water. It was recommended that the treated waste water is adequate for good water quality even though the TSS were 9.01mg/L and 8.7mg/L in both methods used. Introduction Inadequate water supply and water quality deterioration represent serious contemporary concerns for many Municipalities, Industries, and Agriculture in various parts of the world. (Asano, 2002). Several factors have contributed to these problems, which includes, population growth especially in the Urban areas, surface and groundwater contamination, uneven distribution of water resources and frequent droughts. Presently, a recurring research in environmental and water resources engineering has been that waste water can be treated to high quality which could be put to beneficial use rather than wasted. Therefore by applying this conviction to responsible engineering, coupled with the vexing problems of increasing water shortages and environmental pollution, a realistic framework has emerged for considering multiple uses of water through reclamation and re-use in many parts of the world (Adike, 2008). Water pollution control efforts in many countries have made treated municipal and industrial waste water suitable for economical augmentation to the existing water supply, when compared to increasingly expensive and environmentally destructive new water resources development. Water reclamation and re-use however accomplishes two fundamental functions. The functions is that, the treated effluent is used as a water resource for beneficial purposes and the effluent is kept out of the stream, and lakes thus reducing pollution of surface and ground water. Yenagoa is the capital city of Bayelsa State in Nigeria. The water from this city from the research conducted shows that it contains much iron and other contaminants of petroleum products (Wenibo,
