The authors aimed to develop a system for treating emulsified oil discharged from ship engine rooms. The efficiency of the system targeted was to reduce the oil content of the drain to 15 ppm or less so that the drain might be discharged into the sea. A biological treatment system was developed using the fluidized bed in which the drain and sludge are efficiently mixed by aeration and stirring. The specific sludge with enhanced oil decomposing ability is used in the system. The authors performed on-shipboard tests using a pilot test system, whose capacity of the reaction chamber is 0,5 m 3 and oil volume load, 0,4 kg-oil/m3/d, and have confirmed future possible applications to the treatment system for ship. This would bring great reduction in loads on the existing oil separator, reducing its maintenance cost in general.
