Importance of Oxygen

Oxygen is the most crucial constituent of water body health, and its existence directly correlates with how the organisms in that same environment are doing. Oxygen sustains all aquatic animals who need to breathe just like oxygen does for humans on land.

Without oxygen at the bottom of water bodies, anaerobic bacteria produce acids. These acids not only increase acidity but also cause a massive release of phosphorus and nitrogen from organic sediment into the water column; these same toxic gases put fish in danger, including hydrogen sulfide (the rotten egg smell), ammonia, carbon dioxide, and methane which are all poisonous to both beneficial insects as well as other animals who may live around those polluted areas.

Effects of Oxygen Inefficiencies in Water

Anaerobic bacteria is a pathogenic (disease-producing) bacteria found in many different types of infectious diseases. Some examples include cholera, scabies, typhoid fever, shigella dysentery, and bacterial infections such as botulism or boils and sores caused by anaerobic organisms.
These anaerobes kill beneficial bacteria and insects that would feed on the bottom organic sediment. This makes a carbon dioxide-rich environment, which causes acidity to increase exponentially from what was initially just due to pH levels. These microbes are so ravenous for their food source in this CO2-rich environment; they'll eat right through it if given enough time - even though its original purpose is reducing acidity.
Without oxygen at the bottom, beneficial bacteria and insects cannot biodegrade the organic sediment. Significant accumulations of organic sediment follow.
Anaerobic bacteria produce odors that a lack of bottom oxygen can cause.
The lack of oxygen in the water can cause fish kills, detrimental to aquatic life and humans. Fish will be unable to feed on benthic (bottom feeding) insects because there isn't enough oxygen at lower water levels.
Lack of fish enables disease-hosting mosquitoes to thrive, as mosquitoes are natural fish food.

The Process

The concentration of dissolved oxygen found in a water body and available to the organisms, insects, fish, etc., is like an ever-changing balancing act. The primary sources of this are atmospheric deposition and photosynthesis, while other processes such as decomposing plants use up some of it. All these factors add up, which determines how much will exist at any time for animals living in or near water bodies. Any dramatic changes to these concentration levels could be detrimental to aquatic life.

The Importance of Oxygenation

The most important factor in getting oxygen to the bottom of a water body is that it must be done without mixing the nutrients in the sediment and anoxic water at the bottom with any other part of the water column by turbulent mixing. The toxic gases from below cannot mix with anything else in the rest of the water column.

The bottom of the pond is a sediment bed that has some fantastic properties. When we oxygenate, for example, by blowing air on it or adding plants to it, which absorb carbon dioxide and release oxygen back into the water column, this binds up 97% of phosphorus and nitrogen in its sediments where they become food for bacteria and insects. The insect then becomes one of our best fish foods--improving growth rates, health levels, even numbers!

Using Lake Aeration for Oxygenating Water Bodies

Environmental Waterway Restoration creates a world where lakes are healthy. They have created an automatic aeration system that is vastly different from the standard ones, and it's much more efficient at achieving what conventional models can't even touch.
