Three bench scale sequencing batch reactor (SBRs) were set up with a manual control mechanism for the treatment stages to evaluate the effects volumetric exchange rate oneffectiveness of SBR in treating effluent from the slaughterhouses. The average raw slaughterhouse wastewater concentrations for COD, MLSS, NH4-N, NO3-N and TP were 11947 ± 2; 8233 ± 2025; 1,400 ±787; 70.3 ± 49.0; 65.2 ± 9.2 and 261 ± 39 mg/L respectively. Volumetric exchange rate (VER) in the 30 - 50 % range did not show significant difference in the SBR treatment. Therefore, the higher VER of 50% was recommended because it gives higher of volumetric turnover compared to the lower VERs. The SBR treatment process achieved average reductions of 59, 61, 54 and 35% for chemical oxygen demand (COD), ammonia nitrogen (NH4-N) and total phosphorus (TP) respectively.
