Abstrakt: In typical generation of microbubbles by blowing the gas through tiny holes in an aerator, the size of bubbles is much larger than hole exit diameter. Explanation for this discrepancy was found by analysing high-speed camera images of bubble generation. Primary microbubbles, of initial size corresponding to the aerator exits, tend to remain near the location of their formation at the aerator exit - and coalesce there with subsequently formed other primary microbubbles. Typically, this coalescence is repeated several times before the increased final size and position of the resultant larger bubble reaches the limit for separation and ascent.
