Abstract:

This work is concerned with the finding of the optimum conditions for biochemical aqueous wastewater effluents treatment for a local textile mill. The water samples were taken from the Sunflag Textile Mill, Lagos, Nigeria (the aqueous wastewater effluents of the fabrics, leathers, dyes and other solid waste) in equal volumes and subjected to incubation, sedimentation, biological treatment, chemical treatment, and chemical and natural sedimentation treatment. The Box-Wilson method of experimental design was adopted to analyze the physio-chemical and biochemical effects on the wastewater effluents. The physio-chemical and biochemical analyses carried out on the sample revealed that the most favourable optimum operating conditions for the treatment variables are: Temperature 34.5oC, Contact period 40 hours, PH 7.3, Biological Oxygen Demand 28.77 mg/l, Chemical Oxygen Demand 11.71 mg/l and Total Suspended Solid 26.51 mg/l. The analyzed study showed a result that meets the Federal Environmental Protection Agency and Lagos State Environmental Protection Agency effluents treatment standard.


Keywords: Aqueous wastewater effluents, Biological Oxygen Demand , Chemical Oxygen Demand, Total Suspended Solid, Temperature, PH.
