This question is about making O2 free "blendwater" to blend with high gravity brews like the big breweries do, but t the home brew scale.
What am I missing here ...?
I'm sure there is a reason this wouldn't work otherwise I would have heard of people doing it by now ... hopefully someone can explain this to me ...
What is to stop me removing all the oxygen in 19.5l of water by
1) just putting it in a keg with enough SMBS to be total overkill in scavenging all the O2 to negligible ppms - (like a kilo of the stuff if that's what it takes)
And then ...
2) pushing it through purged lines to my R.O. filter (to remove the sodium sulphate byproduct/excess SMBS) and then out through purged lines into a thoroughly purged keg?
Wouldn't that give us an easy way to produce pure, O2-free water which could be used as blendwater for high gravity brewing at the homebrew scale?
Even if you had to boil it first or "rinse and repeat" the whole thing, why wouldn't this work?
I have read that sulphiting water is problematic for RO treatment plants purifying drinking water at the industrial scale because the removal of oxygen can eventually encourage anerobic bacteria to hang out and party in the system - which makes sense at that scale for that purpose -
But if you were really worried about that, couldnt you just put a UV filter first in the chain right before the R.O. unit?
One like this?

Theres no reason that would introduce oxygen would it?
@mabrungard
Any help explaining if I'm barking up the wrong tree is much appreciated.
Edit: I appreciate the rejection rate would mean I would need to use 5x the starting volume to get the final product but for my situation this is a non issue ...
