Oil skimmer is piece of equipment that remove oil floating on the surface of a fluid. In general, oil skimmers works because they are made of materials to which oil is more likely to stick than the fluid it is floating on surface at the same time, the fluid has very little attraction to oil skimmer.
Oil skimmer are usually all that is necessary to remove oil from a liquid. In some cases, However, Oil skimmer may be used to pre-treat a fluid. In this case the oil skimmer removes as much of the oil as possible before more expensive and time-consuming measures are employed. Pretreating the fluid with oil skimmers reduces the overall cost of cleaning the liquid.
There are two basic types of oil skimmers, One type is used to filter and remove oil, debris, and unwanted materials. The other type is used to recover or capture oil in a usable state. Typically, this second type of skimmer is used to clean up oil skim in factories, refineries, and bodies of Water. Application 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 is measured in gallons per minute (gpm) and the removal or recovery rate is expressed in gallons per hour (gph).
There are several different types of oil skimmers, though all designs depend on the laws of gravity and on surface tension in order to function.
