Hey all,
Had seen this process mentioned a few times on here and got talking w/ another brewer at a (much) larger facility here in town. I had seen a de-aerated water tank in their facility during a guild meeting, and assumed they were using it for purging tanks; however, he told me their current SOP is to just use regular city water. While agreeing that de-aerated water would be more "optimal", they said they've tested it both ways and the difference was pretty negligible considering the slow, gentle push out of the tank w/ inert gas.
We were wanting to try this out for our next scheduled hot clean/breakdown, but like many can't afford a DO meter at the moment. Does anybody that uses this method have any real world data they could share? Is the single push out w/ CO2 enough, or would a couple 5 psi purges after be good insurance?
Cheers and thanks in advance!
