Pond & lake Circulation and Oxygenation

There are many products and systems designed to aerate lake water. These range from high-maintenance diffused air/oxygen systems using membranes and complex manifolds layouts to simple floating splashers and rotors. While these systems introduce a certain amount of oxygen into water there is a wide array of effectiveness and efficiency among these methods.  The process of oxygenation  is a challenging event! 
Incomplete oxygenation with high running costs is the norm - expensive installations requiring high-energy input frequently deliver mediocre performance - and in aquatic applications it is difficult to measure efficacy. Although quantifiable
standards are hard to find common logic provides convincing evidence. Check out aeration & oxygenation and consider the review of various approaches below - it could save your fish!

Dissolved oxygen is a vital and volatile substance! Oxygen depletion in ponds lakes and fish rearing tanks has serious consequences for fish health. In deep lakes, stratification causes massive volumes of water at lower levels to be dangerously low or devoid of oxygen. Shallow lakes and ponds can be rapidly depleted of oxygen during hot weather. An increase in water temperature promotes an increase in microbial activity, fish will be more active and feed more, these activities consequently increase the demand for oxygen, however as the temperature of water rises the concentration of dissolved oxygen falls. During summer months, and in particular during thundery weather dissolved oxygen can be very quickly reduced to the point where fish are seen gasping in distress at the surface.

The WMS is a simple device, It takes water from one location, oxygenates it, then moves it to another location. The diagram above shows the circulation pattern, and all this occurs 360º around the WMS. With lakes of differing depths, we can set the WMS to draw water from a fixed depth, to destratify,  reoxygenate and distribute treated water over an area up to 200m across.

How the airmaster WMS circulates pond water
The Aquafoil device is at the heart of the oxygenation process. Fully evaluated at Hamburg University Fluids Laboratory, the Aquafoil has been proven to oxygenate water to 100% saturation at all temperatures relevant to aquatic applications.

Compared to other aeration systems, the compactness of the WMS oxygenator belies it's efficiency.
The ability to treat large volumes of water reliably and at low running costs make the WMS the class leader.
To get the best from this product we need to know some details of the lagoon, pond, lake or pit needing treatment.
