Abstract: Abstract:The international convention MARPOL 73/78, as enacted by IMO, has entered into force, regulating ships to install equipments for treating sewage water containing oil. The bilge water discharged directly into ocean is regulated to contain oil of 15 mg/L or less. A dynamic hydrocyclone oily water separator is practically designed and constructed. A motored rotor generates a highly swirling flow inside the cyclone chamber. Utilizing the nature of different specific gravities, oil and water is separated by the oily water separator. Handling with bilge water sampled from fishing boats, the 15 mg/L discharge regulation of IMO is fulfilled. Treating 3000 ppm mixture of lubricant oil and water, experimental results show that 85 to 93% separation efficiency is attained for an underflow rate less than 1.2 L/min. Optimum separation effect is achieved at 2000 rpm rotor speed, and at an overflow to underflow rate ratio around 5.
