Abstracts: Oil waste that enter the ocean come from many sources, some being accidental spills or leaks, and other being the results of chronic and careless habits in the use of oil and oil products. Most of the waste oil in the ocean consists of used oil from cities, farms, untreated waste disposal from industrial facilities, and unregulated recreational boating. It is estimated that approximately 706 million gallons of waste oil enter the ocean every year, with over half coming from land drainage and waste disposal. Offshore drilling and production operations and spills or leaks from ships or tankers typically contribute less than 8 percent of the total. The remainder comes from routine maintenance of ships (nearly 20 percent), hydrocarbon particles from onshore air pollution (about 13 percent), and natural seepage from the sea floor (over 8 percent). This has caused ever lasting damage to aquatic life. The base behind this project is to separate the oil from water to the maximum extent possible. This project deals with separation of oil from water with the help of belts mounted on pulleys. The belts carry away the oil and the water stays back in the tank. The oil which sticks to the belt can be scooped out and can be collected into a vessel by providing piping arrangements. The collected oil can be reused for many purposes. Belt type oil water separator was designed and the efficiencies were found out and compared, by using variety of belts. The belt providing highest efficiency separates more oil in less amount of time. The project finds applications mainly in industries for maintenance purpose where time is the most important factor. Also the set up finds application along with the ships to separate oil from ocean or sea water where oil spills have been reported.
