A bubble curtain in Florida used to stop debris entering the marina.

A bubble curtain is a system that produces bubbles in a deliberate arrangement in water. It is also called pneumatic barrier. The technique is based on bubbles of air (gas) being let out under the water surface, commonly on the bottom. When the bubbles rise they act as a barrier, a curtain, breaking the propagation of waves or the spreading of particles and other contaminants.


It can be used for the following purposes:

In June 2010, Okaloosa County, Florida used air bubble curtains to help protect their Destin Pass coastline from oil produced in the Gulf of Mexico by the Deepwater Horizon oil spill. They hoped to push oil up to the surface for booms and skimming boats to collect the oil. British multinational oil company BP, who the U.S. government named as the responsible party for the oil spill, was billed for the cost of the project.[7]

The technical system basically consists of a compressor and pipe or hose with nozzles. When used to reduce acoustic waves from pile driving, a distribution manifold made of plastic or rubber is commonly used.[8]
