Sorry, that's the way it is from residential to commercial to
industrial
water treatment. But take another stab at defining what was actually
said;
over-softened.
Ion exchange softening increases the TDS (total dissolved solids) of
the
water very little. And it's not corrosion of the anode rod that
causes
the
glass lined steel tank to rust through.

Various industries and disciplines do use terms differently
but their spokesmen should know the difference. No ordinary
person thinks pure water refers only to lack of biologics.
Shoot, "Have some pure water son, sorry it full of DDT and
every other insecticide. I suppose your industry doesn't
concider acidity either, so here is my last gasp. Maybe
over-softened means too basic, but I would think that
rusting would be more associated with too acidic.
Over softened is sort of like over-stopped, except everyone
know what stopped means, and few people really know what
softened means and if they did they would say, "What the
hell!" But to reduce corrosion to zero in drinkable water,
you essentially have to use pure water. Well, the anode is
there to prevent the tank from rusting through, preventing
or lack of preventing is the cause of the rusting.
BTW, where does all that damn salt go?
Are you saying I don't know the terms of my industry? The ordinary
person of
today pays little attention to correct terminologies and make up their
own
as they go. Who was it that said pure when we were speaking about
oversoftening?
I didn't say that about terms, I said every industry has
their own terms. Yep, the ordinary person doesn't know
much. I didn't say that.
Using your definition of the word pure, or at least its usage today, the
water that my industry can call pure is deionized water at 18 megohms.
Not my definition of pure. Pure water is what you have when
you triple glass distill water. Like the term Chemically
Pure (CP)
To prevent corrosion, we look at the causes and if there are any in the
water, we buffer the acidity, reduce the DO and CO2 content along with
the
chlorides and sulfate, H2S and go on. None of them have anything to do
with
purifying water BTW. Even in the terminologies applied by the common
folks,
they see purifying as filtering and then usually, that means removal of
chlorine, anything floating in the water or otherwise smelly. They
mostly
don't mean the other A-Z thingies found in water because many don't know
of
them; that's usually due to them not reading and having attention spans
measured in seconds. All due to their life style choices of making every
penny they can so they can qualify for more credit and have more
'things'
and simply not having enough time, or energy.
I agree, most people don't know about all the a-z thingies
but they assume that filtering removes all the harmful
stuff.
The vast majority of the 'salt' goes into the drain line and out to
drain.
7.85 mg/l per each 10 gpg of compensated hardness exchanged is added to
the
water.
That's not a lot but how does that compute in ppm of sodium
for a fairly hard water?

I see where I have a typo above concerning the 7.85 mg/l sodium added per
each 10 gpg.... it should say 7.85 per each 1 gpg. Sorry about that. Skim
milk has 530 mg/l per 8 oz glass. Those under sodium restricted diets count
their sodium intake and know how to keep it under their personally
acceptable levels per day. Many common foods and beverages have much more
sodium than say 20 gpg water that has been softened by ion exchange water
softening. Also, getting much sodium into the blood stream by drinking water
containing sodium is at best very questionable.
Distillation is not commercially viable as a solution to treating water to
"pure" quality water, and without carbon filtration, certain things found in
supposedly potable water will not be removed by distillation; such as gasses
and volatile chemicals.
