I don't use them because of the name. If you drink from them that will be
what they play at your funeral.

Subject: Re: [TN] DI Water - Will I die? - NTC Friday


Hi folks! This has been a very fun and fascinating Technet discussion
thread. And since its Friday, I just had to ask the question: "Don't folks
have tap water available in their facilities for drinking purposes?

Hello paranoids, Rudy, and other technetters - (Don't you people watch
Monk?)

RO,DI, Distilled, what's the difference?  (also, nice the see the list so
active after the last couple of years)

DI, removes ions, cation and anion.  Can adsorb some organics.  Single beds
of separate cation and
anion resins can get down to 4-5 ppm depending on incoming water quality.
Mixed beds (both types
together in one column) can get down to about 0.25 ppm.  Can get bacterial
growth on columns (rare).
Particles can pass through.

Distilled water, expensive.  Distillers have carry-over (like leakage in
IX) and the usual pure distilled water
is triple distilled.  We used distilled water as a blank for a zinc system
certification and still got 5 ppb zinc
in the sample.  Distilled water tastes flat because the dissolved gas is
driven off during distillation.

RO water.  RO uses a membrane,  Various membrane pore sizes but the
tightest will remove 99.6 or
99.7%  of the TDS in the incoming water.  It will also remove bacteria and
most organics over 200
molecular weight.  Our 550 ppm water in Santa Barbara comes out at less
than 10 ppm after an cheap
undersink RO.  Commercial systems would get it under 3 ppm or equivalent of
a cation/anion separate
bed system.  That 3 ppm would be 90% sodium chloride.

Can you drink it?  Sure.

Will it hurt you?  Not as much as a soda or coffee.

Will it leach out all the good stuff from your body?  No.  It will dilute
the acid in your stomach but tap water
with calcium will tend to neutralize the acid as well as dilute it.  So I
predict that people who drink "pure"
water will have more problems with heartburn and eat more Tums (all things
being equal).  I drink RO
water and diet pepsi and don't buy Tums but I'm probably living on borrowed
time.

Will bacteria growing on your carbon filter hurt you?  Probably not because
most bacteria are not harmful.
Even coliform bacteria is not harmful, just an indicator of contamination.
You are full of it all the time (no,
I'm not).

The acid in soda pop is carbonic.  The carbon dioxide gas that makes the
fizz dissolves in water and
makes H2CO3, carbonic acid.  It can lower the pH in IX and RO systems down
to below 4.  It is easily
stripped out with air or nitrogen.  If they add citric acid to the soda, it
will also add to the lower pH but
usually the amount if organic acid is minimal compared to the CO2.

Just remember, if you drink RO, DI or Distilled water, you need to
supplement with Calcium and
Magnesium because water is usually a very good source of calcium or, when
you are 104, you will have
brittle bones.  (of course, high calcium diets may be responsible for
kidney stones)

Bob Mesick

old times sake)
