This is the first product that WPI introduced. This was done because the Oxygen WavePlane is a Electricity –WavePlane without the turbines, and therefore a finished product early in the development.

​

Not only does the WavePlane produce a surprising pumping effect, but its oxidation ability is just as impressive.

​

Normally water's ability to hold oxygen is expressed by the point of saturation - the amount of oxygen that can be stored in fresh water of a given temperature. Water of 20°C holds 9,09 mg O2/liter and of 0°C 14,56 mg O2/liter. Water's ability to bind oxygen decreases relative to the increase of temperature bearing in mind that the point of saturation is generally specified based on static water. The amount of oxygen in moving water is often significantly higher than in stagnant water.

​

Having received already oxidized water from the initial wave and then passed through the whirl tube it is ensured that the device always pumps highly oxidized water.

​

The Oxygen-WavePlane generates two downward eddies with opposite spins. An added benefit from the eddy is the creation a larger tangent surface at the outlet ensuring more oxygen being transmitted into the surrounding waters.

​

When the two eddies is working with opposite spins a "whisk effect" occurs. The rotation of the two downward whirls draws in colder water from the bottom. The differences in temperature and the kinetic energies ensure a maximum oxygen utilization.

​

The Oxygen-WavePlane located at a site with an average of 20 cm waves and 12 mg O2/liter, producing a minimum of 60 tons of oxygen per year - sufficient to break down:

​

· 60 tons algae or

· 15 tons nitrogen or

· 30 tons fish feed

The oxygen WavePlane in operation

​

In the spring of 1999 a three tons floating structure with a large “shark fin” was anchored in Mariager Fjord - the first prototype of the Oxygen-WavePlane.

Tests were carried out during the summer and autumn of 1999. The flow speed in the eddy was measured and oxygen and temperature conditions were tested around the device and at a site 500 meters away.

​

It was proven that the Oxygen-WavePlane is capable of pumping water down through 17 meters of water with large salt- and temperature variations. The depletion of oxygen was clearly being reduced without changing the temperature gradients, i.e. the pump was working as expected.

​

The Oxygen-WavePlane is probably one of the least expensive devices for oxidizing large areas. Not only is it cheap to install and run, but also flexible and environmentally friendly.

​

One devise is capable of ensuring healthy oxygen conditions in a medium polluted water environment the size of approximately one hectare.
