De-ionized water - how made?

De-ionized water - how made?

(OP)
How is de-ionized water made? We use 5 k-ohm and 2 M-ohm water for cooling. Is 2 M-ohm water more "aggresive" in terms of attacking metal components (corrosion)? Thanks in advance.

RE: De-ionized water - how made?

Dear Garrett,

I believe that the production of deionised water envolves its forced passage through 2 resins of different polarity, being that the resin positively charged will remove the negative ions and the resin negatively charged will remove the positive ions. I think another way is through the use of specific membranes. I know this isn't much help, but I remembered a site that might help...not sure, give it a try...

Hope that was somewhat helpful...
