Lab scale experiment was carried out to study applicability of BM (Beneficial Microorganisms) to the conventional SBR system for the shipboard sewage treatment. BM has been successfully applied to the wastewater treatment by the SBR process and hence this system maintained a stable effluent quality together with an increased treatment efficiency, meeting the requirements of IMO regulations. The SBR system facilitated by BM would be a suitable process for cruise ships in terms of the malodor control, treatment efficiency and operation conveniences.

There have been several problems in treating shipbard sewage due to special environmental conditions of ship, such as limited space, rolling and pitching, change of temperature and so on It was suggested that Sequence Batch Reactor (SBR) might be suitable process for overcome these problems in terms of small size, high capacity of treating wastewater and full automation. In this study a SBR process was employed for biological treatment of organic wastes in the shipboard sewage. This process was able to remove nitrogen and phosphorus as well as organic matter efficiently. Afore than 95％ of chemical oxygen demand(COD) were removed. In addition, about 97％ of total nitrogen (T-N) was reduced. The total phosphorus(T-P) reduction averaged 93％. A disturbance operation caused by the treatment of Methylene Blue Active Substances(MBAS) was not observed.
