Produktbeschreibung

High Quality Content by WIKIPEDIA articles! A pneumatic barrier is a method of containing oil spills. Air bubbling through a perforated pipe causes an upward water flow that slows the spread of oil. It can also be used to stop fish from entering polluted water. A pneumatic barrier is an active (as opposed to passive) method of waterway oil spill control. (An example of a passive method would be a containment boom.) The pneumatic barrier consists of perforated pipe and a compressed air source. Air escaping from the pipe provides a "hump" of rising water and air which contains the oil spill. Anchors keeping the pipe in a decided spot are helpful. At water current speeds exceeding one foot per second, the pneumatic barrier no longer functions effectively, limiting deployable sites. The release of compressed air in the water adds oxygen to the local environment. This may be particularly useful in an area which has become a dead zone due to eutrophication.
