Bubble size

What bubble size is correct?

Oxygen transfer can be achieved with fine bubbles. An efficient aeration system produces bubbles up to a maximum of 2 mm in diameter. The porosity (openings) of the aerators, however, should be much smaller in order to produce 2 mm size bubbles. The average is 100 Mu (= microns which is 0.1 mm). Fine air bubbles can coalesce (clump together) into a large air bubble which is unwanted. System Dimensions, pressure loss and velocity all affect the air bubbles.

Oxydent aerators are designed and tested to always produce the perfect bubble size for efficient oxygen transfer!
