The lucrative treatment of sugar industry wastewater is a tricky mission. In the current study, an effort was made for the management of sugar industry wastewater. The synthetic sugar wastewater is primed in the laboratory and used for the experimentation. A laboratory scale Aerobic Bio-Reactor was planned and fabricated for the treatment of Industrial wastewater to observe the intensity changes of Chemical Oxygen Demand. The Aerobic Bio-Reactor was accomplished with both suspended as well as an attached growth process. The effect of OLR on the recital of an ABR reactor depends on a integer factors which sometimes have a disparate outcome, mostly conflicting, on the performance of ABR reactor. Researchers have accounted an increase in the effectiveness of high rate aerobic reactors with mounting OLR. The COD reduction was conquered at less in the early stage and increased and achieved a steady state. The utmost COD deduction effectiveness was attained at 91.42% with an organic loading rate of 1.591 Kg COD/m³.day. Apart from the different technologies the Aerobic Bio-reactor proves the healthier one for treating industrial wastewater which can be considered as a trustworthy, secure and cost efficient method in favor of the treatment of sugar industry wastewater. To achieve the goal of reusing the wastewater, again the treated effluent was analyzed by the technology of adsorption process using Silver nanopowder as a chemisorbent and the maximum COD removal efficiency was 100% with the dosage of 0.25 g at a pH of 6 with a at the contact time of 120 minutes were obtained.
