self induced gas flotation

self induced gas flotation

Hello, it's the first time that I write in this forum. I need to ask for an opinion. I am working on a self induced gas flotator cell. I designed the cell and the agitator (like Wemco Agitator). When I put in service the agitator I see only vortices and not bubbles. How can I induce the air without the use of an external gas flow? I have foreseen one nozzle on the top of the cell connected to the stand pipe of agitator in order to regulate, by means of a valve, the recirculation of the gas needed to form the bubbles while the agitator is in service as shown in attachment.

Please suggest me what I need to improve in order to see the bubbles

Many thanks in advance

RE: self induced gas flotation

Don't think there is any method to self induce an air supply. That is the reason air is supplied from a compressor/blower.
