Air bubble techniques
Air bubble techniques are based on the bubble barrier produced when compressed air is fed into a submerged, perforated hose, creating a series of bubble plumes rising from the holes. The rising bubbles cause a vertical current of air and water to flow to the surface, in turn generating a flow of water towards the barrier in the lower layer of water and away from the barrier in the upper layer. This has a mixing function, which can be useful in aerating a stagnant lake.
Table I describes and illustrates various techniques developed by a major manufacturing company.
