Which type of skimmer collects oil through a turning drum?

The drum skimmer is specifically designed to collect oil by using a rotating drum that picks up the oil from the surface of the water as it turns. This mechanical process allows for efficient collection of oil, as the drum rotates through the oil slick, and the oil adheres to the surface of the drum. As the drum turns further, the oil is then moved to a collection area where it can be stored or processed.

This type of skimmer is especially effective in situations where oil is spread over a large area, as its rotating action can continuously gather oil without the need for suction or siphoning, which is characteristic of other skimmer types. The design and operation make it particularly suitable for certain environmental conditions and types of spills, emphasizing its practical application in pollution response efforts.
