Abstract
A process and apparatus for treating oily wastewater, such as bilge water or ballast water, generated on a ship. The process uses a combination of a centrifugal separation step and a membrane separation step, such as an ultrafiltration step. The membrane separation step uses a dense, non-porous filtration membrane. The process is able to remove both emulsified oil and dissolved oil from the wastewater to low levels.
