Bubble Curtains

Daily Tech and Science #-1482

Bubble Curtains

A bubble curtain is a system that releases a continuous stream of air bubbles into water, forming a vertical barrier or "curtain" of bubbles. It is created by pumping air through a perforated pipe or hose placed on the seabed, riverbed, or other underwater surfaces. As the air escapes, it rises in the form of bubbles, creating a visible and functional barrier.

Common Uses of Bubble Curtains:

Noise Mitigation:

Bubble curtains are often used in marine environments to reduce underwater noise from activities like pile driving, seismic surveys, or other industrial processes. The bubbles absorb and scatter sound waves, protecting marine life, particularly those sensitive to noise, such as dolphins and whales.

Containment of Pollution:

They can help contain oil spills or debris by forming a barrier that limits the spread of contaminants.

Fish Guidance:

Bubble curtains are sometimes used to guide fish or deter them from entering specific areas, such as power plant intakes or construction zones.

Thermal Barriers:

In lakes or reservoirs, bubble curtains can help manage water stratification by mixing different layers of water to balance temperature or oxygen levels.
