Design principle of fish pond aerator

In aquaculture production, the use of aerators is becoming more widespread, but some fishermen do not yet understand how it works, and in practice they are blind and random. Therefore, first understand how it works, and master its use in practice.

The purpose of using an aerator is to add dissolved oxygen to the body of water. This involves both the solubility and dissolution rate of oxygen. The former includes three factors: water temperature, water salinity and oxygen partial pressure; the latter includes three factors: the degree of unsaturation of dissolved oxygen, the contact area and mode of water-gas, and the movement of water.

A stable condition in which the water temperature and the salt content of the water are. Therefore, in order to achieve oxygenation to the water body, it is necessary to directly or indirectly change the oxygen partial pressure, the contact area and mode of the water-gas, and the movement state of the water. In response to this situation, the measures taken when designing the aerator are:

1. Use mechanical parts to stir the water body to promote flow exchange and interface renewal;

2. Disperse the water into small droplets, spray the gas phase, and increase the contact area of ​​the water-gas;

3. Inhale by a negative pressure to disperse the gas into microbubbles and press into the water.

Various types of aerators are designed and manufactured according to these principles, either by taking measures to promote oxygen dissolution or by taking two or more measures.
