Would it need to be stored in a vacuum evacuated container? Normal air will dissolve over the amount of time it takes to pull 10 gallons.The cheap ones have tens of milliliters per minute flow rates. At 20 ml/minute it would take 3 hours to process 1 gallon. You would need to think ahead to make your water.So, who's the first to incorporate one of these into their brewery?
Hadn't seen those. I'll bet somebody here jumps on one, for the outlet side of their RO system.
Edit - If you're committed to low O2 water, it would beat the hell out of preboiling.
Ok, then there's that!
