I have also thought about air bubbles as well, but I am leary that I may end up with super or overly oxygenated water. I intend to use this liquid at a later time and it may effect the end product if I have overly oxygenated water in the procress. I think I might be a little to picky on this one and may have to test it further though.
Have you considered using pure N2 gas instead of air to provide bubble agitation? It might not be practical for your project, but I do know that it used in the food and beverage industry, sometimes as a replacement for CO2 in draft or fountain beverages and specifically to pressurize containers of beer.
