Physicochemical Characterization and the Effect of Flow-Distance on Correlation between Chemical and Biochemical Oxygen Demands of Industrial Wastewaters | Chapter 05 | Advances in Applied Science and Technology Vol. 3
This work was carried out to establish the effects of the activities of a cluster of industries in Jos-South Local Government Area of Plateau State, Nigeria, on the environmental quality of the industrial area. Some physicochemical parameters –temperature, pH, turbidity, suspended solids (SS), total solids (TS), total hardness, alkalinity, biological oxygen demand (BOD), chemical oxygen demand (COD), heavy metals (Cu²⁺, Co²⁺, Fe²⁺& Zn²⁺), phosphates, nitrates, sulphates and chlorides –of the wastewaters from the various industries were investigated using standard protocols. Also, the influence of flow-distance on the empirical correlation between biochemical oxygen demand (BOD) and chemical oxygen demand (COD) of the wastewaters was investigated. Wastewater samples were collected at point-sources and at 25, 50, 75 and 100m di...
