Discharging accumulated bilge water from the ship is very important in order to maintain its stability and safety. However, the bilge water that contains contaminants, including waste oils and oily wastes, must be treated prior discharging to the sea. The International Convention for the Prevention of Pollution from Ships (MARPOL) has set strict oil discharge limit in order to minimize sea pollution. Thus, an efficient oil–water separator must be installed to separate the oil from the bilge water. This chapter introduces and discusses the working mechanisms, as well as advantages and disadvantages of the available oil–water separation techniques for bilge water treatment, which include gravitational, centrifugation, flotation, coagulation and flocculation, biological processes as well as absorption and adsorption.

Water contamination is one of the major environmental and natural resource concerns in the twenty-first century. Oil contamination can occur during operation of machinery, oil exploration and transportation, and due to operating environment. Oil spills occasionally occur during oil exploration and transportation. Water contamination with various chemicals is a major concern with growing population and unsafe industrial practices of waste disposal. Commonly used oil–water separation techniques are either time consuming, energy intensive and/or environmentally unfriendly. Bioinspired superhydrophobic/superoleophobic and superoleophobic/superhydrophilic surfaces have been developed which are sustainable and environmentally friendly. Bioinspired oil–water separation techniques can be used to remove oil contaminants from both immiscible oil–water mixtures and oil–water emulsions. Coated porous surfaces with an affinity to water and repellency to oil and vice versa are commonly used. The former combination of affinity to water and repellency to oil is preferred to avoid oil contamination of the porous substrate. Oil–water emulsions require porous materials with a fine pore size. Recommended porous materials include steel mesh and cotton fabric for immiscible oil–water mixtures and cotton for oil–water emulsions. A review of various approaches is presented in this paper. This article is part of the theme issue ‘Bioinspired materials and surfaces for green science and technology (part 2)’.
