Femtosecond (FS) laser-induced surface structuring is a robust, maskless, non-contact, and single-step process for producing micro- and nanoscale structures on a material’s surface, which remarkably alters the optical, chemical, wetting, and tribological properties of that material. Wettability control, in particular, is of high significance in various applications, including self-cleaning, anti-fouling, anti-icing, anti-corrosion, and, recently, oil–water separation. Due to growing energy demands and rapid industrialization, oil spill accidents and organic industrial discharges frequently take place. This poses an imminent threat to the environment and has adverse effects on the economy and the ecosystem. Oil–water separation and oil waste management require mechanically robust, durable, low-cost, and highly efficient oil–water manipulation systems. To address this challenge superhydrophobic–superoleophilic and superhydrophilic–underwater superoleophobic membrane filters have shown promising results. However, the recyclability and durability issues of such filters are limiting factors in their industrial application, as well as in their use in oil spill accidents. In this article, we review and discuss the recent progress in the application of FS laser surface structuring in producing durable and robust oil–water separation membrane filters. The wide variety of surface structures produced by FS laser nano- and micromachining are initially presented here, while the excellent wetting characteristics shown by specific femtosecond-induced structures are demonstrated. Subsequently, the working principles of oil–water separation membranes are elaborated, and the most recent advances in the topic are analyzed and discussed.

ABSTRACT A compact oil spill recovery system made up of a special oil suction float, an eductor-driven hydraulic fluid conveying unit, an oil/water separating unit, etc., was devised to the basic design concept of the previously-developed Mitsubishi hydraulic tanker desludging system and installed in a small, self-propelled, twin-hull craft. A 9.60 m long, 4.10 m wide, and 1.40 m deep experimental oil spill recovery ship completed in this manner successfully cleaned up a slick of heavy oil, 7 m × 30 m in area and 0.7 – 2.0 mm in film thickness, in less than three minutes at 0.5 – 1.0 kt and proved very stable, steerable, and easy to operate. Oil content of water at the outlet of the oil/water separating unit was less than 1 ppm. A range of oil spill recovery ships have since been designed, fully weighing opinions of potential customers as regards such items as economy of operation, and capacity.

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution. The term is usually applied to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land. Oil spills may be due to releases of crude oil from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined petroleum products (such as gasoline, diesel) and their by-products, heavier fuels used by large ships such as bunker fuel, or the spill of any oily refuse or waste oil. This paper deals with the problem of recovery of spilled crude oil. It has been observed that the separation efficiency is greater for high range of viscosity and oil water ratios. Separation efficiency data on tests of water versus diesel, crude oil, and IS0 460 gear oil will be presented for two sizes of separators. Oil spills can have disastrous consequences for society; both economically and environmentally. As a result of these consequences oil spill accidents can initiate intense media attention and political uproar. Despite substantial national and international policy improvements on preventing oil spills adopted in recent decades, large oil spills keep occurring.
