Versatech RBS Skimmers operates by utilizing the oleophilic surfaces of a rotating brush/drum/disc to attract oil and reject water. As the skimming element rotates through the oil/water surface, the oil adheres to the surface and is removed by a scraper. The recovered oil is collected in a common sump and pumped away. The skimming element modules, brush/drum/disc, can be changed easily in a few minutes. The system also offers an internal weir system for heavy oil concentrations.
