Inside Out Grooved disc oil skimmers

摘要

Mechanical oil skimmers are just one of many tools used to clean-up oil spills. The most basic skimmers are non-selective, weir-type skimmers that collect huge quantities of water along with the oil, requiring secondary separation of oil and water. Other skimmers are more selective, carrying out a first-stage separation of oil from the water during recovery. In general, selective skimmers float over sections of oily, contaminated water and skim the oil off the surface using oleophilic drums, discs, belts or brushes. After collecting oil from the surface, these devices all transfer it to temporary storage for eventual disposal. The highest rate of recovery ever recorded was 1,100 gallons of oil per minute - until now.
