Four Ways To Introduce Dissolved Oxygen Into Your Waterbody
Lakes and ponds help us manage stormwater, yield drinking water, provide fishing and recreation opportunities, and maintain beauty in our communities. But ongoing management is necessary to ensure they continue to function properly and remain healthy. To maintain a balanced waterbody, one crucial element needs to be present: oxygen. One management tool professionals have relied on for decades to introduce oxygen into waterbodies is aeration. Oxygenation can be achieved with several types of aeration equipment:
1. Oxygen Saturation Technology (OST)
A new and exciting industry innovation is Oxygen Saturation Technology (OST). Unlike other solutions, this tool targets lake anoxia and water quality problems at the source — the sediment. This premium water quality management solution injects oxygen directly into the water which allows the oxygen to stay in solution and disperse, blanketing lake sediments with high levels of oxygen. Furthermore, this system can introduce oxygen at a specified depth without impacting the thermal stratification or layers of colder water. This allows for oxygen to be placed, and stay where it is needed most at the sediment-water interface.
2. Submersed Aerators
Submersed aerators, on the other hand, provide aeration through circulation. Compressed air is pumped through diffusers placed on the lake or pond bottom. As bubbles rise, they circulate the water and bring bottom water with low oxygen levels to the surface where oxygen can be absorbed. This circulation pattern mixes the water and provides oxygen at lower depths.
3. Floating Fountains
Floating fountains spray water with pleasing patterns into the air. As the water falls across the surface, it creates turbulence that facilitates the transmission of oxygen into the water column while allowing submersed gasses to escape. Fountains provide multi-faceted benefits and can even be adorned with lighting for added beauty. When it comes to oxygenation, fountains are most beneficial in shallower waterbodies.
4. Nanobubble Technology
Nanobubble Technology systems pump water out of the lake or pond, inject it with nanobubbles and then release the water into the waterbody. Nanobubbles are microscopic—so small that they do not rise to the surface; instead, they drift and eventually dissolve, releasing oxygen after several days or weeks. Nanobubble treatments are best suited for smaller, shallow waterbodies (approximately 3 acres or less). Each of these tools functions in different ways, but they are all designed to cultivate a well-balanced waterbody.
In Summary, Dissolved Oxygen Is Crucial
So, what does an oxygen-rich waterbody look like? Oxygen creates water quality conditions that help neutralize phosphorus and nitrogen — common nutrients that, in excess, can pollute our valuable water resources. Lakes and ponds with more balanced water quality conditions are less hospitable to algae and nuisance weed growth. In turn, this prevents the release of potential algal toxins, limits the development of bottom muck and bad odors, and supports the proliferation of beneficial microbes, zooplankton, native fish, and other healthy aquatic life.
Aeration is a crucial tool in our toolbox of sustainable solutions — which also includes scientific laboratories, drone technology, highly-targeted herbicides, and more — but it alone cannot keep your waterbody balanced. Every aquatic ecosystem is different and requires a unique combination of strategies to achieve the trifecta of health, beauty, and functionality. The most efficient and budget-friendly way to achieve your goals is through an annual management program, which leans on an entire toolbox of solutions so that your waterbody receives the most effective and customized care all year round.
