Abstract: The Performance of an Aerobic Bio-Reactor (ABR) for the behavior of synthetic sago processing wastewater was investigated. The system with 13.3 liters of working volume was accomplished by attached as well as suspended growth process. The experimental analysis was carried out with the influent Chemical Oxygen Demand of 3920 mg/l, 4360 mg/l and 4640 mg/l at Hydraulic Retention Times (HRT) of 11, 14, 17, 21, 28, 42, 84 and 141 hours. During the experiment, pH plays an important role and the Dissolved Oxygen was maintained within the permissible limit continuously. In an ABR, the maximum COD removal efficiency was attained 91.20% with an Organic Loading Rate (OLR) of 1.518 kg COD/m3. To achieve the goal of reusing the wastewater, again the treated effluent was analyzed by the technology of adsorption process using zinc oxide nano powder as a Chemisorbing and the maximum COD removal efficiency of 100% was observed with 0.75 g of dosage content at the pH of 6 at the contact time of 180 minutes.
