Making Silver ions for Spa? Ozonator, Getting Rid of Old Spa Tips
David L
salts are very cheap, but the exact concentrations could be tricky.
Silver copper and zinc are all used. Ionized silver is used by some
for reported health benifits, but I don't think drinking heavy metals
is a good idea.
After reading the sites selling silver ionizers for making a drinkable
solution...Apparently a "smaller molecule" is created with low voltage
(~9volts) and pure water using electrolysis, basically a battery
hooked to a piece of silver in a water bath.
Guess the silver needs to be hooked to one side or the other. Think
the trick is to catch the silver in solution while it's migrating to
the opposite pole of the battery while in the solution.
I thought pure water would not conduct a current? Anyway I don't want
to drink the stuff, just get a low concentration of silver in my tub
to kill bugs cheap, so a pinch of salt a little silver wire and more
voltage would be fine.
Anyone actually have any hands on experience making this stuff, to
drink or bathe in it?
I'm also using corona discharge made ozone, which is cheap and
powerful. One company, (Dell) sent me a free ozonater out of
warranty(3mg O3/hour output) for a replacement, when I bought a
neighbors spa (cheap).
I have another bigger commercial ozonator and air dryer traded for
work from at a tropical fish store. I fixed and rebuilt it, but found
out that too much ozone is not a good thing. It can put out about
.26grams/hour of ozone, but should be turned all the way down when fed
through the seperate 24 hour on circulating pump venturi.
I'd say the 3mg/hour@24hours/day is just about the right dose.
One problem with creating ozone from a small arc of electricty and
untreated air is the byproducts. Water vapour in the air, when passed
through the high voltage "arc" makes Nitric acid residue in the
associated tubing...not a good thing to make. So an air dryer is used.
The air dryer pulls air through alternating heated ceramic pellets in
2 metal tubes. One tube absorbs moisture while the other is getting
heated by an element to boil of the moisture. A little controller
board alternates the flow through a selenoid valve and runs the
heating timer.
The final "polishing" filter is a tube full of silica gel, which
catches the bit of moisture that gets through the ceramic pellets.
Those crystals can be cooked out manually, when the indicator blue
crystals turn pink. Holds about at least 10%, maybe 20% water by
weight in a few experiments.
For anyone that wants to get rid of a used spa. The price was $300
through a spa mover!! Just the dump charge is about 100$.
$300 was $50 more than the cost of moving the the new one down the
street.
I suggest using a sawzall and a long blade. Suit up and wear a
respirator if your sawing fiberglass, yuuck! A good shopvac is very
useful here.
The free local yearly trash pick up will take away items less than 4
feet long and under 75lbs. Saved $300 for anywhere from 1.5 to 3 hours
work. I've done a couple. Two, one foot long blades makes the job much
easier! I was using 6 inch blades and that was not long enough. The
newer soft plastic spas filled with foam are much less messy. Nothing
is worse than fine fiberglass dust. Cutting through all those flex
air/water tubes buried deep within the foam spa innerds is tricky hard
part.
Oh, and if you move a spa get a piano dolly with BIG wheels for uneven
or soft surfaces. Lay down plywood on the lawn. Use steel pipe as
rollers for moving on smooth flat surfaces.
Spas are heavy and heavier and cumbersome too. Pay some strong,
skilled guys, instead of risking a potential back injury if in doubt.
Or saw it into little pieces;-)
The reason so many spas are advertised "free" is because of the high
moving cost. Old spas are less than worthless. By the same token, a
good, recent model spa, can be purchased for very little, just factor
in the moving cost. It's one project that provides many hours of
pleasurable rewards, once completed.

And thats the evidence that its complete unscientific crap.
None of the rest of the silly crap worth bothering with.
