Abstract :The establishment of piggery farms in residential areas is becoming an issue of public health concern owing to the discharge of its contaminated wastewater into the surrounding environment. Due to potential pollutants in these effluents, this study also attempted treating and recycling wastewater from selected piggery in FUTA community. The available piggery farms insert ignore into journalissuearticles values(medium and small-scale); cannot afford the cost of most existing municipal wastewater treatment plant. In furtherance, designing an effluent treatment plant made from locally available plastic materials which consist of bio-filters such as coarse, fine sand and activated carbon was considered. The water quality characteristics was carried out before the treatment of the wastewater in order to know the present contaminants. Moreover, the microbial-treated water was channeled into the filtration tank, where the larger particles of dirt insert ignore into journalissuearticles values(gravel and coarse sand); were removed. Also, grease and oil were removed by the activated carbon. The performance of the treatment plant was evaluated on the effluents and the results showed a decrease in Biological Oxygen Demand, Dissolved Oxygen, Phosphorus, Total Nitrogen, Total Dissolved Solids, Total Suspended Solid, Total Solids and Heavy metals insert ignore into journalissuearticles values(Cadmium, Lead and Zinc);. Surprisingly, there was an increase in pH value of the microbial-treated water due to the detention time. The values obtained after treatment were compared to the Food and Agricultural Organization insert ignore into journalissuearticles values(FAO); water quality standard. This showed that the water is safe for discharge into the environment insert ignore into journalissuearticles values(waterways); and it can be used for irrigation purposes.
