Smooth and Grooved Drum Surfaces
Smooth and grooved drum oil skimmer technology has been extensively tested by Ohmsett and researched by the Bren School of Environmental Science and Management, University of California, Santa Barbara. Grooved drums have a higher recovery rate with viscous oils, whereas smooth drums offer higher efficiency with lighter oils such as diesel.
How Drum Skimmers Work
As the floating drums rotate, oil adheres to the surface separating it from the water. Wiper blades (scrapers) remove the oil from the drums, depositing it into the collection trough where it is pumped to a storage location. Elastec drum skimmer systems are available in pneumatic, diesel or electric power. A drum skimmer test model is available for demonstration.
Elastec drum skimmers can also be applied in industrial applications.
