The wave aerators
Wave aerators or wave drivers are forming a constant source of waves for long distances of the pond. The thin surface layer of the water is most saturated in oxygen both of the surface aeration of oxygen and of the activity of photosynthetic seaweeds producing oxygen.
However, if this layer is stationary, the oxygen diffusion into the depth of water is too slow. Wave aerators mix this thin layer with the more deep saturating them with oxygen.
Wave aerators are very effective. They use the low power motors and gearboxes with a high gear ratio. Due to this, a slow rotation having a large diameter rotor creates annular flows in the reservoir, activating considerably the aeration’s process.
On 1 kW of electricity, the wave aerator provides the introduction of about. 2 kg of oxygen into the water. Economisation and efficiency of this type of aerators are made them the most common in the world aquaculture.
One of the purposes of wave aerators is wasting out of the ice. Constantly working aerator prevents icing on a large pond’s area. The size of the unfrozen water depends on the air temperature and the heat reserve in the pond*. Working in the winter, wave aerators ensure the oxygenation of the pond with minimal consumption of energy by the activation of the surface aeration.
