Understanding the science behind aeration technology is the key to selecting the right equipment for your lake. LakeTech staff will gather the required data so you can make an informed decision about your lake's aeration needs. Selecting a system based on estimates of surface area or depth is not sufficient. There is no one-size-fits-all solution, so spending the time and resources to select and design the optimal system is vital.

Diffused Aeration & Circulation Systems

The objective of a diffused aeration system is not to dissolve gas bubbles into water but rather for the bubbles to entrain water causing vertical lifting and mixing. Diffusers are not effective in shallow lakes and circulators should be considered. Aerating fountains or surface aerators, when sized and located correctly, are an effective alternative.

Why Aerate?

All lakes stratify as a result of thermally driven density gradients. When this happens, the water in the bottom of the lake becomes trapped and cannot mix with the upper layers and typically becomes depleted of dissolved oxygen. Understanding how stratification effects your lake is vital to successfully designing a diffused aeration or circulation system.



  • The limitations of diffused aeration and circulation systems may require more sophisticated technology. Oxygen Saturation Technology (OST) is a state-of-the-art aeration system that dissolves oxygen directly into water. These systems can maintain dissolved oxygen ¬†concentrations as high as 20 mg/L directly over and into the sediments, where oxygen is needed most, providing exceptional water quality, not achievable with any other system on the market.
