In collaboration with the Atlantic Botanic Garden of Gijón and the University of Oviedo, we have developed a system of ultrasonic control to avoid eutrophication of the Laguna Boreal diversion dam.

The characteristics of this ecosystem can bring about a risk during the warmer time of the year the presence of stratification which is harmful to the ecosystem that surrounds it. This occurs when creating a warm, oxygen-rich surface layer on the one hand, and a cold, oxygen-poor deep layer on the other. If the concentration of oxygen falls to levels of anoxia, most of the organisms in the bottoms die, resulting in an increase of nutrients in the environment and causing the proliferation of bacteria and algae that are positioned in the surface layer of the lagoon. and further enhance this process.

The most efficient, sustainable, and safest way to avoid eutrophication is through ultrasound control that limits the growth of algae.

The placement of ultrasound generating devices would allow the maintenance of the lagoon at sustainable levels.

Three different origins of microgeneration networks will supply the system: hydraulic, wind and solar. The hydraulics will be carried out my the hidrotornillo which replaces the system with energy, taking advantage of a small waterfall existing at the exit of the dam. This Hydroscrew will produce and deliver a constant power of 1.2 kW. 

The three connected demonstrators allow for the supply of sufficient energy thanks to the measurement and control infrastructure to improve the energy efficiency of all the devices that are part of this network.
