I came across mention in one of my brewing science books about how breweries remove oxygen from their liquids by bubbling a stripping gas like CO2 or Nitrogen through them. I would speculate this works because it creates a pressure gradient by flushing the liquid with a pure gas having a very low partial pressure of oxygen. As the stripping gas bubbles through the liquid, the oxygen diffuses out of solution and into the gas where it is vented. So... assuming you wanted to reduce the dissolved oxygen content of your strike water, would it be feasible to attach a diffusion stone to your CO2 tank and bubble CO2 through your strike water to lower the dissolved oxygen ? it seems we are able to oxygenate the wort to 10ppm with only a couple of minutes of diffusion, I wonder how long it would take for CO2 gas to remove the oxygen?
