Effects of Cassava Wastewater on Opa Stream in Ile-Ife, Nigeria (Published)
This study is aimed at determining the impacts of indiscriminate disposal of cassava wastewater into the nearby stream. The cassava wastewater quality was tested in accordance with the standard methods for the examination of water and wastewater for both physical and chemical parameters such as temperature, conductivity, hardness, pH and turbidity. The physicochemical properties of both water and cassava wastewater was conducted before and after the disposal of the cassava wastewater and the result of the experiments showed that the effluent is acidic with pH of 3.8 and of high conductivity of 40 µs/cm2. The cyanide content is also very high with 11.88 mg/kg as compared to 1.5-3.5 mg/kg recommended by WHO. The total solids, and total suspended solids are also in high range of 2000 mg/kg and 3000 mg/l respectively. Its hardness is 800 mg/l, chloride 2000 mg/l. The dissolved oxygen was not detected. The physicochemical properties of the after experienced significant difference (p<0.05).
