Treatment of agro-industry wastewater using the RBC system and the combined Upflow Anaerobic Sludge Blanket - Rotating Biological Contactor (UASB - RBC) system was investigated. The raw wastewater was highly contaminated with organic matter as indicated by COD (3500 - 4000 mgl −1 ), BOD 5 (1620 - 1800 mgl −1 ), and TSS (375 - 402 mgl −1 ). RBC system led to an effluent that does not comply with the Egyptian Standards for discharging effluents to canals or drains. The combined system (UASB-RBC) achieved remarkable pollutants elimination. The treated effluent has BOD 5 < 15 and COD < 40 mgO 2 l −1 . TSS, and oil and grease, are below the recommended limits for discharging industrial effluents into the surface water.
