Annex IV of International Convention for the Prevention of Pollution from Ships (MARPOL 73/78), adopted by the United Nations specialized agency ‘International Maritime Organization’, provides a set of guidelines for shipboard sewage and manure waste treatment. This study was performed to customize and optimize the previously developed, Marine Equipment Directive-certified, large-scale marine sewage treatment system at a Bench-scale to evaluate the chemical oxygen demand (COD) of shipboard sewage. This sewage treatment system uses a combined process of a continuous batch reactor (SBR) and a membrane bioreactor (MBR) to suit the ship environment. This study aimed to derive the optimum operating conditions for the treatment of organic matter at the Bench-scale. The Submerged Membrane-Sequencing Batch Reactor (SM-SBR) method applied during this experiment excluded the precipitation process from the existing SBR method and treated sewage through a membrane using MBR process. The existing SBR method is performed through react (mixing and aeration) → sedimentation → draw, however, the sedimentation time in combined SM-SBR process is reduced, this study was performed in a repetitive operations of mixing and aeration processes. The developed device consisted of a down flow anaerobic reactor, screen, bioreactor, and membrane reactor, and in the case of raw-water, considering the water runoff; a constant water level was maintained through a pump. In this study, the experimental conditions 1~4 for stirring : aeration states were set at 70 : 50 min, 80 : 40 min, 90 : 60 min, and 100 : 50 min, respectively. The COD removal efficiencies for conditions 1~4 during each operating condition were 96.69%, 95.93%, 96.86%, and 96.29%, respectively. Further more, findings of this study suggest that the highest organic matter removal efficiency was achieved at condition 3 (stirring : aeration = 90 : 60 min).
