Effect of gas hold up The solid suspension into a bubble column causes to formation of large bubbles. An increase of bubble size increases the bubble rise velocity, and reduces the residence time of bubble in reactors [9]. The solid particles in bubble column reactors are in micron size and suspended in liquid.

[PDF] Mixing in Bubble Column and Airlift Reactors ...

Mixing behavior of three geometrically equivalent 0.06 m3 bubble column and airlift photobioreactors was compared for use in microalgal culture. Mixing was characterized in terms of the axial dispersion coefficient, mixing time, circulation time and Bodenstein number. Measurements were reported in tap water and sea water, as used in growing microalgal biomass.
