The Aquaculture Aerator is used to increase the level of oxygen in a tank or pond. Water temperature, salinity, and atmospheric pressure determine the dissolved oxygen concentration. These variables are beyond the culturist's control, but they can be controlled to maximize the benefits. The aerator can be operated at different rates depending on the time of day and weather conditions. During sunny afternoons, a surface aerator can be used.

The main unit of these aeration devices is an air compressor. It can be either a root-type blower, a membrane pump, or a compressor. The air moves into the pond through a perforated tube that is suspended in the water column. Upon entering the pond, the perforated tube allows oxygen to enter the pond. The aerator then passes the oxygen through it, ensuring that the water is fully oxygenated.

An aerator with a higher SAE can transfer more oxygen than a similar aerator with a lower SAE. However, as the pond water becomes oxygen-saturated during the day, the aerator's efficiency decreases. When the pond's dissolved oxygen concentration is supersaturated, the aerator's function is reduced, transferring oxygen from the water to the air.

Although an aerator can effectively transfer oxygen, its efficiency varies with the dissolved oxygen concentration. As a result, a 3.0 mg/L pond will only have half of the aerator's measured SAE. As a result, aerators can be useless for maintaining the dissolved oxygen concentration. Furthermore, an aerator's SAE will be affected by the amount of suspended solids and salinity in the water, and the temperature of the water will reduce the aerator's oxygen transfer rate.

Large-scale aeration systems can be costly and require the use of a compressor or blower. They can be installed on a bank and can be moved in several ways. For example, the paddle can be set to float horizontally and vertically, or the aerator can be set to rotate at an angle, producing a turbulent current. Another advantage is that the aerator is portable and can be used anywhere in the pond.

The dissolved oxygen budget in an aquaculture pond is highly complex, and the aerator's efficiency varies considerably with the water temperature. A typical aerator will transfer approximately 4.0 kg of 02 per KwH of water, and it can support up to two liters per minute of oxygen. Its maximum output can be increased to three times the rate of a circulating aerator.

It is important to aerate water in order to maintain healthy conditions for fish. Properly aerating water will ensure optimal results for your aquaculture operation. The unit comes standard with a Franklin Electric Submersible motor, which is ideal for smaller ponds. Its unique impeller will increase air contact and dissolved oxygen in the water, which is crucial for the growth of your plants.
