Pond & Lake Aeration

Pond Aeration Overview

The main goals of pond aeration are to increase dissolve oxygen content in the water and reduce stagnation. There are three main ways to achieve this:

• Bottom Diffused Pond Aeration

These systems use a compressor housed in a cabinet on shore, to pump air to diffusers at the bottom of the pond. The diffusers create a boiling effect that causes the bottom water to push toward the surface. The greatest oxygen transfer occurs when that water contacts the surface. A properly sized system should be able to turn the volume of the pond multiple times per day.  Bottom diffused pond aeration is the most efficient means of enhancing water quality in ponds over 7 feet deep. Now available in solar!

• Oxygenation Saturation Technology

This exciting new technology is a state-of-the-art aeration system, available commercially for the first time this year. OST dissolves oxygen directly into the water which eliminates bubbles, turbulence, nutrient and sediment resuspension, and undesirable mixing. These systems can maintain dissolved oxygen levels as high as 20 ppm directly over and into the sediments. These levels of oxygen provide exceptional water quality, not achievable with any other system on the market.  OST systems are suitable for ponds over 1 acre in size with a 10′ max depth. If trout are desired, a minimum of 15′ of depth is recommended.

• Pond Fountains

These units pump water into the air by way of a submerged pump attached to a float that is placed in the pond. While they are aesthetically pleasing, pond fountains are mainly surface aerators that cannot pull water from deeper sections of the pond. They are, however, ideal oxygenation options for shallow ponds (<7′ deep). But not all fountains are created equal!  Highly patterned units will have a reduced flow which limits surface mixing. There are specific brands and units that offer more robust surface mixing capabilities. Please see our Pond Fountains page for more information, or contact us to request a quote.
