In comparison to other techniques, coarse bubble aeration is very inefficient in the way of transferring oxygen. This is due to the large diameter and relatively small collective surface area of its bubbles.
Fountains are a popular method of surface aerators because of the aesthetic appearance that they offer. However, most fountains are unable to produce a large area of oxygenated water.
through a hose to a unit placed at the bottom of the water body. The unit expels coarse bubbles , which release oxygen when they come into contact with the water, which also contributes to a mixing of the lake’s stratified layers. With the release of large bubbles from the system, a turbulent displacement of water occurs which results in a mixing of the water.
