Re: [APD] Don't Drink Distilled Water [SAFETY] (was "Storing largeamounts of RO water")

Wow I spaketh  !

It's ok to drink purified water - RO or Distilled.   But you have heard a
lot about that today already. ;)

Sodium Ions are pretty small, Potassium and Chloride are smaller and will
pass to some degree through and RO membrane but no all of them in the water
(due to effect of concentration gradients at the membrane boundary layer).
All other things in the water will not pass the RO membrane, including
Calcium ion.


And just for grins, here is a pretty cool paper that talks about ion
transport in living cells.

Have a great week.
