• Nitrogen nanobubbles


    Capturing nitrogen

    Capturing nitrogen in water with nanobubbles is a much more effective method than flushing water with N2-gas

    Flushing with N2 gas

    Flushing with N2 gas, flow 1 L/min, generates bubbles that rise rapidly to the surface. This method has limited transfer efficiency.

    N2 nanobubble generator

    With the nanobubble generator, N2-flow 1 L/min, transfer efficiency is much higher, only a small number of tiny bubbles escape to the surface.

  • Water deoxygenation

    Removal of dissolved oxygen from water is an important process in order to mitigate issues such as corrosion, oxidation of food and pharmaceuticals.


    Deoxygenation can be done by injecting inert gasses such as nitrogen into the water. Using a concentration gradient, nitrogen forces the dissolved oxygen into the gas phase which is then vented out from the liquid.
