Benefits of using Aerators to diffuse water

So why is entraining water in Pond & Lake Bed Aeration so important? It all has to do with the mixing and blending of the water column. Thermal stratification occurs in most ponds/dams & lakes during the summer. Thermal stratification is the layering of warmer, oxygen rich water near the surface on top of cooler, oxygen deprived water towards the bottom. The transition between these layers is called the thermocline. The differences in water density at the thermocline prevents the water from mixing. Our Aerators use diffusers to pump air through the diffuser membranes. This air then makes its way to the pond surface in the form of millions of tiny bubbles. As these bubbles travel upward through the layers of thermal stratification they entrain water with them. This water is carried to the surface where it becomes naturally oxygenated, thus aerating the waterbody.

By aerating and circulating from the pond bottom up, the toxic gasses previously trapped under the thermocline can escape, thereby providing a balanced habitat for aquatic life. The aeration also creates aerobic conditions near the pond bottom where microbial processes can naturally break down nutrients which would otherwise be used in the production of noxious aquatic weeds and algae.

Lake bed aeration systems – the most efficient and cost effective way to aerate water bodies. Our lake bed aeration systems provide a complete ready to install solution for waterways with low oxygen levels, sludge build up and temperature variances in the water column (stratification).

Over time water ways can develop stratification which is a separation of the warmer top layer of water and the colder deeper layers. Whilst the top layer receives oxygen from the air and supports marine life the bottom layer loses oxygen through anaerobic breakdown of organic matter which can result in foul smells, fish kills, poor clarity, weed and algae growth.
