"Air-lift" aerators [7,12,13,14,15]: Mechanical components are totally absent (wear, corrosion, and jam are excluded).The water is "pneumatically" aerated and stirred in the "aeration reactor" with minimum energy consumption. This last one, undoubtedly represents an interesting advantage for locations where there is no access to the electricity grid, like sea lochs or lagoons.

2018-9-10 · Air-lift and bubble-column photobioreactors are vertical bioreactors that inject gas from the bottom of the bioreactor. In general, they are compact, inexpensive, and easy to use. Air-lift systems perform better than bubble columns on small scales because air-lift bioreactors have more consistent flow patterns that efficiently keep cells .

Uses of a method of producing small bubbles of gas in a liquid include gas transfer in airlift bioreactors and anaerobic digesters, and particle separation. The method uses a source of the gas under pressure, a conduit opening into a liquid and oscillating the gas passing along the conduit. The oscillation is effected by fluidic oscillator, comprising a diverter that divides the supply into .
