Allgie has patented a very efficient and low-cost nanobubble generator.

Nanobubbles are bubbles so small that the gas dissolves in water.

At Allgie, the CO2 dissolved in the water allows microalgae to feed not only on the surface, but also throughout the water volume. Algae can feed on CO2 even at the bottom of the tank.

In the previous video example (Japanese), it is possible to observe saltwater fish living with freshwater fish thanks to oxygen nanobubbles dissolved in the water.

Fish farming can benefit from this device as the greater amount of oxygen dissolved in the water allows more fish to grow per volume of water in a sterilized environment (O2 nanobubbles).
