A laboratory scale Hybrid Aerobic Bio-Reactor was designed and fabricated for the treatment of Industrial wastewater. The Hybrid Aerobic Bio-Reactor (HABR) was accomplished with both suspended as well as attached growth process. Oxygen was supplied in the entire process of operation. The reactor has been continuously operated at mesosphilic range with an Influent Chemical Oxygen Demand (COD) of 848 mg/l, 824 mg/l, 864 mg/l, 856 mg/l, 872 mg/l, and 888 mg/l. The result showed that the HBR attained a steady state from 15th day to 18th day. During the start up period the pH and Dissolved Oxygen plays an important role. The COD reduction was attained 7% in the initial stage and it was incremental up to 12th day and decline from 12th to 14th day and then attains a steady state from 15th day to 18th day. The maximum COD removal efficiency was achieved at 96.45%.
