Steve,
Does this companies initials begin with Ionics?
I've heard the same spewl, but never questioned it, this is
not an area I have any desire to become the expert in. Thats' why they're
there.
The same type system was installed at a few companies I've
been with and I assume it is designed to work best this way.
If you learn something different, I'd really be interested in
knowing about it.

Hi ya'll!
I gotta question, do any of you
that deionize city water for your cleaners,
have a carbon bed before your
cation, anion. and/or mixed beds? Now I'm not
talking about a closed-loop Ion
exchange filtering system, just straight
water deionization.
Well, I
discovered that we do (for now anyway). I called the vendor that
services us
(I'm tempted to say who it is, and they're big. Because I think
they've been
ripping my employer off), and asked why there is a carbon bed in
front of the
other beds.
Because from my understanding and experience the only reason
you need a
carbon bed is to filter out and remove the heavy metals and
organic
contaminates before they got to your cation and anion beds if
you're
closed-loop. I could always tell when my carbon beds were getting
full, (or
they weren't getting back-washed daily) when I started foaming in
my
cleaners.
Anyways, the guy said that the carbon beds will somehow
extend the life the
ion exchange resins by filtering the chlorine contained
in city water...which
I tend to question. When I was out in California (which
has some of the
hardest, most chlorinated water in the country) never was
there a Carbon bed
used before the ion exchange columns for my D.I. water,
and this was the same
company that serviced me in California as well. Was he
tap dancing, or was
there some truth to his logic?
I think the real
reason is because a 3.6 cu. ft canister of either Cation or
Anion beads are
$97.50 ea., while a 3.6 cu. ft. canister of Carbon is $200
ea...and nobody
here ever questioned it.
