Over the last decade, membrane filtration has appeared as a rentable and a powerful process for purifying large volumes of wastewater (mostly in the form of bilge water and ballast water) generated by naval and commercial vessels. Ceramic membranes with high resistance to extreme conditions can treat more and more effluents. The aim of this paper is to develop an industrial process that can separate hydrocarbon (HC) from oily wastewater using a membrane process.
