Gaia Oxygenation Technology
Gaia USA, Inc. has developed a technology that can increase DO levels much more rapidly and to higher concentrations than micro bubble aeration from diffusers. As mentioned above, diffusers introduce atmospheric oxygen which has a concentration of 21%. Gaia injects 95% pure oxygen. The oxygen is not just passively dispersed through the water column as micro bubbles that quickly rise to the surface and gas off, but is mixed into the returning water stream as ultra-fine bubbles measuring ~ 107 nanometers (.107 microns) in diameter. Independent lab testing has shown Gaia’s technology to have over a 90% gas transfer efficiency. The water stream exiting the Gaia mixing valve has an oxygen content of ~ 17 ppm and, over several days can raise the DO level of large areas to 8 ppm or more depending on the volume of water to be treated.
Ultra-fine bubbles possess amazing properties. These bubbles rise extremely slowly through the water column enhancing the opportunities for the oxygen to positively impact the DO level. These bubbles, due to their lengthy suspension in the water, migrate away from the introduction site, increasing DO in the water body significant distances from where the oxygenated water is originally dispersed.
Gaia recommends a combination of its technology with bio-augmentation. Diffusers supply sufficient oxygen to the depths of the water body to encourage growth of aerobic bacteria to consume the decomposing matter at the bottom. The much higher oxygen levels Gaia technology introduces, causes the bacteria to multiply much more quickly, more rapidly remediating the problem.
DO can be driven high enough with Gaia technology to force algae die offs because the oxygen becomes toxic at high concentrations and crowds out the nitrogen and carbon dioxide the algae need for photosynthesis. Chemical remediation will be unnecessary.
The Gaia system is very simple. It consists of an oxygen source (oxygen concentrator or liquid oxygen), a pump scaled to the appropriate flow rate and a Gaia UFB mixing valve. Multiple systems can be deployed based on the water volume for treatment. The pump extracts low DO level water, pushes it through the valve where oxygen is injected and mixed, and returns treated water, high in oxygen, to the bottom of the lake or pond where oxygen levels are lowest.
If the lake continues to be used for irrigation of the surrounding landscape, plant life will also benefit. Not only will the elimination of harmful chemicals reduce plant stress, but irrigation with high DO water has been found to very effective in enhancing plant growth and health.
