Do
electromagnetic devices work on calcium salts?
(as reprinted from the Opflow, February, 2003)

First,
let’s look at magnetic or electromagnetic water treatment units.
Numerous related Internet sites fall into three classes: those promoting
a particular brand of water, those established to debunk the entire
idea of magnetic treatment of water (and other uses), and a few
that try to address the issue from the scientific viewpoint.
According to some magnet vendors, magnets can be used to improve
blood circulation, increase automobile mileage, improve plant growth,
soften water, prevent tooth decay, and even increase the strength
of concrete. A few of these claims are backed by experimental evidence,
but most are not.
There is almost no scientific evidence that these devices consistently
work. Some scientific investigations have found some level of effectiveness
in electromagnetic devices used to reduce the amount of tenacity
of scale, but none are able to report the reason for the achieved
effect. Attempts to reproduce results nearly always fail, probably
because other uncontrolled factors influence the results.
Several studies show electromagnetic devices may have an effect
on the type of scale and the attachment of that scale when applied
to industrial boiler water, possibly from an interaction between
silica and the calcium carbonate scale deposits. However, these
studies seldom provide conclusive scientific evidence.
Consumer Reports conducted a two-year, side by side study of water
treated by one brand of domestic magnetic treatment device compared
to untreated water and found no difference in scale formation in
parallel domestic water heaters. I found no studies that show that
electromagnetic devices are effective in domestic, first-use water
applications…”

The best product of choice is not always the cheapest. Remember
above all else, you get what you pay for.

News
from over there
SeaQuest
is finding its way into more and more desalination systems
as this type of water supply becomes even more established
as a water source in specific parts of the world short of
ground and surface water. The reason is simple. It works.
There is not other product that can function at the variable
pH ranges produced with desalinated water and the low to non
existent alkalinity other that SeaQuest. If you are servicing
a desalination unit anywhere in the world, call Aqua Smart
for further information.
