Aeration of water

Oxygen as water quality parameter

Oxygen is the single most important water quality parameter. There are many ways to aerate a water body. Some of the available devices and methods used today are covered here. Each system has its time and place as a management tool.

Keeping your water oxygenated

The main objective to using an aeration system is to provide sufficient dissolved oxygen to the water. The sufficient amount varies from pond to pond or lake to lake. Much of it centers around the biological oxygen demand (B.O.D.) and water temperature.

All of the living organisms in an aquatic ecosystem need oxygen. Although fish consume oxygen from the water column, their excrement asserts a higher B.O.D. As faeces and other organic litter builds up on the bottom it forms a high organic sediment. Micro-organisms, on the bottom of the pond, feed upon this organic matter and subsequently use up the available oxygen. During night time hours plants and algae further reduce the available oxygen.

Need advice?

For the professional aeration of large water bodies IRASSS provides the Air-Duck™ water aerator. However, there are more ways to keep your water oxygenated, for example with enzymes.

If you think professional aeration of your water body might be needed or need professional advice about lake cleaning please go to our contact page for information how to contact IRASSS.
