A DI resin operates a little differently.
"Deionizers are complete “ion exchangers”. In a deionizer, water flows through a chamber filled with “cation” and “anion” synthetic resin beads. Millions of hydrogen ions (H+) are loosely attached to each cation bead and hydroxide ions (OH-) are attached to each anion bead. Passing water exchanges all its positive ions for H+ ions and all its negative ions for OH- ions.
Released H+ and OH- ions react with each other, forming H-OH or H2O, which is water."
And water, we all know, is good fer drinkin" ! [img]tongue.gif[/img]

<font size="2" face="Verdana, Helvetica, sans-serif">Im realy talking about DI cartrige cation and anion, Drinking deionized water is not a good idea. First of all if dionized water comes in contact with metal, it will dissolve it into the water. If you drink pure water it will take minerals form your body becasue it is "Ion aggressive". Also purified water grows a great deal of psudemonas bacteria. Remember, you were told never drink water form a stagnant pond. Every drinking water system I have seen in a home is a stagnant pond. To stop water from growing massive amounts of bacteria, you must add an inhibitor (chlorine, choramine, Iodine etc...) or you must keep it moving at a constant 5 feet per second. If if you remove bacteria and then store it in a tank, storage bladder or in a pipe, it will rapidly re-grow bacteria.
