Self-cycling fermentation (SCF) control was applied to a semi-continuous, aerobic, fixed-film reactor for the treatment of simulated and real brewery wastewater. The simulated wastewater was treated at 25°C. After approximately 3 hrs, 86% to 96% of the soluble BOD (SBOD) was removed, producing an effluent with a SBOD between 169 mg/L and 412 mg/L. The treatment of real brewery wastewater was undertaken at 25°C and 35°C, and was operated under ammonia-nitrogen deficient condition. 83% to 92% of the total BOD (TBOD) was removed after 3 hrs at 25°C, and after 1.5 to 2 hrs at 35°C. The treated effluent produced had a TBOD between 120 and 438 mg/L. The suspended solids in the treated effluent contributed between 63% and 71% of the TBOD. Hence, better treatment efficiency would have been possible if an efficient clarifier was installed, or the suspended solids were removed from the brewery wastewater prior to treatment.
