RO Water filtering ?

RO Water filtering ?

Postby Trackerdan » Sun Oct 19, 2014 12:40 pm

Tapping into the brains trust of this forum hopefully..

Does anyone use reverse osmosis water filtration prior to brewing?, I only collect rainwater where I live, I do run pleated and carbon cartridge filters to 5 microns, but I am wondering if it would be better to run a reverse osmosis setup, then adding certain minerals to that.

If anyone does something similar or has any info on rainwater analysis that would be great.

The only thing Ive ever used is un filtered rain water, straight from the tank for my ferments.
I never seen the need to use anything else.

I'm on Rain water too . We have a 5 micron sediment filter straight out of the pump then under the sink is a 1 micron followed by 0.5 micron filter to stop the Ghardia in our Drinking water as some members of the family are susceptible to it .

For Wines and Beer that might sit around for a while I use the filtered water but for Fermentation's , I just use the Tank water now ( via the 5 micron sediment filter) as Its going to be distilled anyway . I don't have any issues with bad ferments . Regarding minerals , well all I see going in the tank is water and a bit of decaying leaf litter and bird shit , plus the usual acid Rain ( pH is normally 6.8-6.9 when we are on constant rain) .
When we run out of water and get a top up from the waterman , it goes slightly higher pH as he pumps straight out of one of the local creeks .

I'd rather drink this stuff than what they drink in town .
