Compressed air oil barrier in operation

A compressed air oil barrier is a device that can be used to prevent liquids floating on water from spreading.

Working principle

Compressed air escaping from a line laid under water rises in bubbles and carries water particles with it. This raises the water level in the area of ​​the bubbles reaching the surface. The water flows off to the side. A water flow is created, which flows against a possibly spreading oil slick and thus prevents it from spreading over the barrier.

application

With a laid on the bottom of the water porous line you can z. B. shut off a port basin in order to prevent accidentally leaking oils or oil products from spreading during loading. These are then much easier to collect or vacuum. Compared to mechanical barriers, such as. B. with floating bodies , a compressed air oil barrier has the advantage that it does not hinder traffic on the water and can be easily activated and deactivated by switching the compressed air on and off.
