No. 4: Comparison of the potential for dissolving oxygen gas between
    micro bubble diffuser and eco-Bubble®-400 (May 27, 2014)

We compared the potential for dissolving pure oxygen gas to the water between a microbubble diffuser that is used in the aquaculture facilities in European countries and eco-Bubble®-400. The diffuser can release bubbles with 100 to 400 µm in diameter, while eco-Bubble® can produce micro/nano-bubbles of less 40 µm in diameters.

Results: DO of the water reached the saturated conditions about four times faster in the use of eco-Bubble® than the microbubble diffuser. To control DO levels of the water by bubbling with pure oxygen gas, the consumption of gas is saved about one fourth by the use of eco-Bubble® to the conventional diffuser.
