Abstract
A dual drum skimmer is provided for the removal and recovery of oil floating on water. The skimmer includes two oil pick-up drums 11 and 12 arranged along a common axis which pick up oil and deposit it in a collection trough 16. Oil deposited in the collection trough 16 is directed to a reservoir trough 22 arranged on the opposite side of the drums 11 and 12 from the collection trough 16. The drums are formed as hollow, closed cylinders and, together with the reservoir trough 22, provide the total buoyancy necessary to float the skimmer. The skimmer is particularly effective in shallow and in trash laden water and can operate in water depths of as little as three inches.
