Deep-Water Aeration System
Deep-water aeration is used when the deeper water, the hypolimnion, in a standing body of water is not adequately supplied with oxygen. This layer of water is relatively unaffected by the influence of the surface. The thermocline, which lies above it, separates it from the surface area, the epilimnion, of a standing body of water. The epilimnion is lit by daylight, is relatively warm and is well aerated.
With the help of air-lift pumps, the deeper water is transported to the surface of the body of water without coming into contact with the thermocline or the epilimnion. After the water has absorbed the oxygen, it is brought back to the deeper area of the lake through downpipes running under the thermocline.
By building the aeration system in sections, it is possible to transport and install it without using a crane, and thereby also possible to reach very inaccessible bodies of water.
