Abstract: Upflow Anaerobic Sludge Blanket (UASB) reactors have been widely used for treatment of industrial wastewater. In this study, performance of a lab-scale up-flow anaerobic sludge blanket (UASB) reactor, treating a chemical synthesis-based pharmaceutical wastewater, was evaluated under different operating conditions. Tubular section is a 240 cm long column with 14 cm internal diameter (ID) and a volume of 9.2 liters. The length of the gas-liquid-solid separator is 80 cm and volume is 20.4 litres The GLSS section is further separated into two parts, bottom half is tapered with a slope angle of 60 and top half is a 20 cm long column with an internal diameter of 22 cm. The COD concentrations used in the present investigation 9900mg/L. At steady state conditions, the reactor resulted in 65 % of COD and 70.2 % of Metoprolol removal efficiency accounting for Substrate Degradation Rate (SDR) of 2.72 kg COD/ m3. d During this study, which lasted for 60 days actual organic loading rate (OLR actual) of 4.25 kg COD/ m -d, the temperature of the wastewater entering the reactor ranged from 30 to 350C, Oxidation Reduction potential was between no heat exchanger was used.
