Abstract

The study assessed the microbiological and physicochemical parameters of wastewater collected between September 2008 and August 2009 from the sedimentation tank inlet and the discharge point of the oxidation ponds of a brewery with a view to determine the efficiency of the wastewater treatment system. The influent wastewater had mean values of total bacterial, coliform and fungal densities of 9.8 × 105 cfu/mL, 4.7×102 cfu/l00mL, and 2.8 × 104 cfu/mL respectively while the discharged effluent had mean values of 2.9×106 cfu/mL, 9.0 × 103 cfu/l00mL and l.5 x 105 cfu/mL respectively. The DOM, BOD and TS of effluent had mean values of 26.0 mg/L, 210.0 mg/L and 406.6 mg/L, respectively, while the mean of the DO concentration was 0.9 mg/L. The mean of the pH and temperature of the influent wastewater were 10.0 ± 0.02 and 38°C ± 0.5, respectively, while those of the discharged effluent were 7.3 and 35°C respectively. The concentrations of mercury and lead in the discharged effluent were higher than acceptable limits.The findings showed that the efficiency of the oxidation ponds was low and hence poses a potential danger to the receiving environment.
