PHYSICO-CHEMICAL CHARACTERIZATION AND TREATMENT OF SELECTED FOOD INDUSTRIAL EFFLUENT BY COAGULATION TECHNIQUE
Publication Date : 01/03/2018
Food processing industries consume large quantities of water. The food industrial effluents in general are characterized by high Biological Oxygen Demand along with fats, oil–grease and many other recoverable nutrients like Nitrate and Phosphorous. In the present investigation thorough treatment studies were carried out on alkwa abattoir effluents in Anambra state, Nigeria using alum, as coagulant. Physicochemical characterization of the effluent was also carried out to check the pollution potential of this wastewater. More emphasis was given on the representative water parameters mainly pH, Electrical Conductivity, Total Dissolved Solids, Biological Oxygen Demand, Turbidity etc. The coagulation was performed with alum at different dosage intervals in order to check the variations in effluent parameters. Present studies revealed that coagulation has better ability to reduce the abattoir wastewater parameters.
