396:(more than 2mm in diameter), 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. In comparison to other aeration 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.

water surface. Floating surface aerators are also powered by on-shore electricity. The effectiveness of a surface aerator is limited to a small area as they are unable to add circulation or oxygen to much more than a 3-metre radius. This circulation and oxygenating is then limited to the uppermost portion of the water column, often leaving the bottom portions unaffected. Low speed surface aerators can also be installed on floats.

As each new section of water is churned, it absorbs oxygen from the air and then, upon its return to the water, restores it to the water. In this regard paddlewheel aeration works very similarly to floating surface aerators.

The low speed surface aerator is a device for biology aeration with high efficiency. These devices are often in steel protected by epoxy coating and generate high torque. The mixing of water volume is excellent. The common power is going from 1 up to 250kw per unit with an efficiency (SOE) around 2

Fountains are a popular method of providing surface aeration because of the aesthetic appearance that they offer. However, most fountains are unable to produce a large area of oxygenated water. Also, running electricity through the water to the fountain can be a safety hazard.
