• For aeration and destratification of lakes, ponds 4
• For the desaturation of water supersaturated with gas, etc...
• AQUASUB is a hydro-ejector which combines aeration and movement of water masses. Used in freshwater lakes or ponds, it brings the oxygen essential to fish life. With a simple design and very robust construction, our devices can be used in all circumstances.
  

FUNCTIONING
A special pressure turbine rotating at 3000 rpm is attached to the end of the motor shaft. The air that arrives through the guide tube is sucked into the center of the propeller by the VENTURI effect. The air mixed with the water is diffused in micro-bubbles in the water current created and oriented towards the bottom. The quantity of oxygen transferred is optimum because the micro-bubbles have a very long residence time in the volume of water pushed.

BENEFITS: A stream of water rich in oxygen

• Reduces fish mortality due to lack of oxygen
• Prevention of the development of phytoplankton (cyanophyceae) as well as weeds.
• Biodegradation (by aerobic bacteria) of organic pollutants held in suspension.
• An increase in fish density, growth rate, good health.
• Circulation and mixing of water masses
• Destratification of bodies of water, lakes, ponds...
• In winter, can be used to keep part of the body of water open.
• The AQUASUB technique: a guarantee of proper operation and performance.
• AQUASUB aerators, developed in our workshops in 2009, are floating, compact devices. They operate electrically: an underwater cable provided allows them to be connected to the power supply on the shore. Mooring is done using simple ropes.
• The particular operation of this aerator makes it possible to combine aeration and mixing of the water. Moving the mass of water optimizes contact with atmospheric air. At the same time, the injection of air into the water ensures a transfer of O2: 0.35 kgO2/h.
• The two types of FLOSUB and AQUASUB aerators can be used combined on the same body of water where they form an effective unit: “Aquasub” promoting water circulation and Flosub or Flobull, oxygenation.
