Nanobubbles for Lake Restoration and Algae Management

For decades we have known that providing dissolved oxygen to the lower layer of lakes can improve water quality.  Lakes can stratify thermally in the spring and summer months isolating the lower layer from the atmosphere.  When that happens, aerobic bacteria can consume the dissolved oxygen that is trapped there in short order and that causes a number of chemical and biological changes to occur.  The primary method of solving this problem has been aeration.

In the last year Nanobubble generators have burst onto the scene.  These systems pump water from the lake into the generator and return water laced with Nanobubbles to the lake.  Nanobubbles are extremely small and negatively buoyant.  About 2,000 of them are smaller than a grain of sand.  These bubbles disperse through the lake.  As they “bump” into organic material, they attach and burst delivering oxygen.  This action will also cause a hydroxyl radical to form and that chemistry can oxidize algae cells and the toxins they may produce.  This can provide 24/7 algae control and over time supplement other lake management activities.

Another unique feature of this type of control is that you can oxygenate the lower portion of the water column without disrupting the thermal stratification that is occurring.  This can provide refuge for fish in the cooler deeper waters.

Aquatechnex can provide a Nanobubble system sized to your lake.  These can be sold directly to your orgainzation, or they can be part of an overall lake management program we perform for you with a set monthly fee.  For more information please get in touch at tmcnabb@aquatechnex.com
