Oil Skimming Selection Guide
Although designs vary, all oil skimmers rely on specific gravity, surface tension and a moving medium to remove floating oil from a fluid's surface. Oil skimmers are simple, dependable and effective tools for removing oil, grease and other hydrocarbons from water and coolants. Often, an oil skimmer by itself can achieve the desired level of water purity. In more demanding situations, oil skimming is a cost-effective means of removing most of the oil before using more complicated and costly treatments such as coalescers, membrane filters, and chemical processes. Selecting the proper skimmer and belt material depends on a variety of factors. Grease typically requires that the unit come equipped with a heater to handle the higher viscosity material. Freezing temperatures also require some sort of heat mechanism as well. The shape or capacity of a tank can affect skimmer selection. While oil skimmers don't cause emulsions, the presence of emulsions in the tank can also be a factor when selecting belt materials.
