The EOLO2 aeration system

The World's most advanced aeration system!

The EOLO2 aeration system is the World's most advanced aeration system. It is a compact machine that conveniently and effectively does it all: aeration, destratification,and sediment removal. The EOLO2 aerator oxygenates by blowing in and dispersing air at depth in micronized bubbles. This mothod is the most efficient for introducing the greatest amount of dissolved oxygen into the water. It destratifies by creating a flow of water at depth, thus unifying temperature, oxygen , and PH levels throughout all areas of the pond.

Operating characteristics at sea level with an ambient temperature of 25℃

1. Efficient and thorough aeration over a large portion of the water volume:
The above two pictures illustrate the difference between the traditional paddlewheel aerator and the EOLO2 submersible aerator. The different results can clearly be seen. Paddlewheeel aerators merely splash the surface water. The air introduced into the water by this method covers only a very small portion of the water area, and the air bubbles are all near the surface. Therefore, this type of aeration does not generate a large quantity of absorbed oxygen in the water. Impeller(mushroom-type) aerators produce similiar results.
The EOLO2 submersible aerator introduces air directly into the water at depth, enough to saturate 15 cubic metersof water with oxygen every minute. At the same time, the 2800rpm propeller causes the oxygenated water to flow at least 35 meters out in front of the aerator. As the above picture demonstrates, this results in absorbed oxygen being dispersed equally over a very large portion of the water volume. The level of absorbed oxygen created is many times greater than that created by paddlewheel and impeller aerators.

2. Adequate circulation and destratification:
Paddlewheel and impeller(mushroom-type) aerators are only able to aerate at the water's surface. They are therefore unable to create a flow of water at lower levels. The oxygen they add to the water is limited to a small area near the surface. This often results in situations similiar to that illustrated in diagram A above: aquatic animals are forced to concentrate themselves into the small areas of oxygenated water that these aerators create, competing for the limited oxygen there.
The EOLO2 aerators high-speed propeller creates a flow of water at depth. This works effectively to mix the different levels of water together throughout the pond. The pond water thus becomes uniform in temperature and chemical makeup at all depths and at all positions of the pond. When this flow of water is combined with the EOLO2's high oxygen-absorption rate, the result is that every area of the pond is equally hospitable to aquaculture animals. Instead of competing for oxygen in small areas of the pond, they freely swim around like in diagram B above.

3. Cleansing of the pond bottom and decomposition of organic particles:
The pond-bottom soil greatly effects the quality of pond conditions. Aquaculturalists know that clean pond-bottom soil is as important as clean water. Even if the source water is excellent, pollutants are created from uneaten food and waste which accumulate and settle on the bottom. This creates a layer of sediment that produces deadly gases and toxic pollutants. The most effective way to deal with this sediment is to lift it off the pond bottom and treat it with oxygenated water.

Toxic gases are emitted from the build up of uneaten food and waste on the pond bottom

The EOLO2 lifts the sediment off the bottom, forcing it to decompose due to its contact with oxygenated water

The end result is thoroughly oxygenated pond water and a toxic-free pond bottom

The three drawings above this process:
1). With poor quality or no aeration, the pond-bottom soil becomes dirty and polluted,
emitting harmful gases and toxins into the water. Oxygen is concentrated near the pond surface.
2). When the EOLO2 aerator is used, the sediment is lifted off the pond bottom and oxygen is introduced into the lower levels of the pond.
3). As a result the organic materials are exposed to oxygenated water, causing them to decompose, and making them harmless. The entire pond-water volume is now adequately clean and oxygenated.

Immediately after operation

10 minutes after operation

30 minutes after operation

The three pictures to the left show a real-life illustration of this process. After only 30 minutes of operation a large quantity of oxygenated particles have floated to the surface as foam. Such foam can then be easily removed from the edges of the pond.
Note:
With its adjustable angle, the EOLO2 can remove pond-bottom sediment without eroding the pond-bottom soil -- this is unlike aerators such as the AIRE-O2 which must always be angled downward (see drawing below)
Conclusion:
Mechanical aeration is a proven technique for increasing the dissolved oxygen content in ponds. In addition to doing a good job of oxygenating, however, an aerator must also circulate the water to eliminate temperature, chemical, and oxygen stratification between various depths of the pond water. The aerator must also work at a depth sufficient enough to treat the pond-bottom soil, keeping it oxygenated and free from deadly toxins that will pollute the water and possibly kill aquatic animals.
There are many types of aerators, but the submersible EOLO2 aerator is the most effective for doing all that is necessary to keep your pond water and soil clean and healthy. The EOLO2 provides the best possible environment for healthy, fast-growing aquatic animals, ensuring larger, quicker harvests, producing greater profits and happy farmers.

 

Without adjustable operating angles, aerators such as the AIRE-O2 cannot operate horizontally and will therefore erode pond-bottom soil
