Oil skimmers are pieces of equipment that remove oil floating on the surface of a fluid. In general, oil skimmers work because they are made of materials to which oil is more likely to stick than the fluid it is floating on. At the same time, the fluid has very little attraction to oil skimmers. Oil skimmers are usually all that is necessary to remove oil from a liquid. In some cases, however, oil skimmers may be used to pre-treat a fluid. Applications for oil skimmers include in-plant pumps, tanks, and coolant systems as well as outdoor cooling and settling ponds. When selecting oil skimmers, important specifications to consider include capacity, removal or recovery rate, and total flow.
These skimmers consists of a geared motor that continuously rotates a Belt made up of special material which allows the oil particles to stick it. These oil particles are then scrapped by a scrapper and collected in a separate oil collecting bin. Oil skimmers are usually all that is necessary to remove oil from a liquid. In some cases, however, oil skimmers may be used to pre-treat a fluid. In this case, the oil skimmers remove as much of the oil as possible before more expensive and time-consuming measures are employed.
