Hi, I think this may be the site and the study of which you speak (very
interesting I might add)...

I think it was just a mention on some Canadian version of an EPA site
that went into various effects of industrial silver waste on fish and the
environment.
Don't recall exactly.
The conclusion was that silver chloride did kill microbes, just not very
well in comparison to several other forms of silver

Ken, can you remember the url? The reports I have come across stated
silver chloride is 300 to 3,500 times less effective than ionic
silver.
These studies were done a while ago, so the quality of the ionic
silver may be very much in doubt. For example, your Silverpuppy will
produce at least 22 ppm cs, whereas a 3 nines may only reach 5 to 10
ppm depending on the wetted area. Jason's 4 nines is probably a bit
less due to the faster current rise with the higher voltage.
Best case, comparing 5 ppm ionic silver to your 22 ppm cs, the
figures on silver chloride should be multiplied by 22 / 5 = 4.4, so
the 3,500 figure may actually be 15,400 times less effective.
A very big problem with these reports is comparing apples and
oranges. How do you ensure you have equal amounts of silver ions and
silver chloride particles? Silver chloride is somewhat soluble, so
how do you state the effectiveness of a partially dissolved
substance?
I don't think silver chloride gained much popularity as a
disinfectant, since I believe it was much less effective than other
forms of silver such as silver nitrate.
In our case, perhaps it might be worth doing a simple milk test with
your known good ionic cs as the reference.
And, perhaps some samples of high particulate cs just for laughs.
Marv Hacker did one with Mezosilver, I'll see if I can find the
link.
Best Wishes,
