I know that this is way off base - but does anyone know how ann ozone
maker works?  I was asked by a guy at work - and have no idea.

Ozone = o3

take oxygen, add electricity and stir....

Happens everytime you get a spark.... or have a high tension circuit,
buzzing away....

It's EASY to make OZONE...

But hard to make sure that is ALL you make....

after all, nitrogen, combines with oxygen too....

An over zealous air ionizer will produce ozone. Also, a certain nm
ultaviolet light (tube) produces ozone. Commonly refered to as
a...... you guess it.... an ozone lamp. Sigarette companies use ozone
lamps to kill the bugs in their product !!. Very thoughtfull of
them......

Hi

This one is of great interest to me as I have a water system at the cabin
(rainwater) That I would really like to get on the ozone and off chlorine.
Any PLANS??? There are small o3 generators available here $100-300. CAD but
all require dryer crystals as part of the system so they won't operate
without attention. I would of course automate my water system with a PIC
and expect it to recirculate and sterilize as required.

My roommate has an ozone air cleaner and it seems to produce occasional
electrical sparks. I had assumed that it worked to produce ozone the way
lightning does: by providing enough energy to fuse on the extra oxygen atom
to the molecule electrically. You can smell ozone distinctly in the presence
of electric motors where the brushes are exposed to the air.

When I was a kid, my father bought a blue box (size of a shoes box) that it was
installed at the kitchen faucet, it incorporated a small water filter element.
The box had a high
voltage transformer and a tube "corona" style generator, electrically connected
to a water valve, the same one used at any laudry washing machines. So, turning
a switch, water flow
was initiated, and in few seconds ozone smell came out of the water.  It was rec
ommended to wash vegetables and dishes. The corona generator was in an empty cha
nger, and by the
"venturi" process water flow sucked air (with ozone) into the water. According w
ith my mom it really worked, vegetables immersed in ozoned water for a minute do
ubled lifetime in
the fridge, and I remember that a 1 year old wart in my finger disappeared after
one week I washed hands there before dinner...

... ozone anyone?

I think its just air flowing over an electric spark causing...

3O  --> 2O

Ozone is generated by splitting an O2 molecule into 2 Os.  Some of the
wayward Os combine with other O2 molecules to form O3.
The O3 is very unstable due to the extra O. Os, by themselves, are VERY
aggressive little things. When the O3 comes in contact with another
molecule the 3rd O will literally rip apart the molecule trying to steal
an O from it so it can be in it's happy little O2 form.
I use ozone in a foam fractionator (protein skimmer). It breaks down
complex proteins for easier removal from the water with the foam
fractionator.

Please keep in mind that while O3 is a very strong oxidant and can be
beneficial for sterilization and disinfecting, it will also attack the
mucous membranes in your nose.  Excessive O3 can cause nasal
irritations, nausea, and headaches. Pets are also very susceptible to
irritation from O3.  O3 will attack most plastics making them very
brittle and I've heard it will weaken fabrics as well (i.e. your
furniture, carpet etc...)
Just like washing your clothes in a strong bleach solution (another
strong oxidizer) will deteriorate the fibers.
O3 is typically generated by the energy in the corona of a spark or
lamp. This energy causes some of the O2s to break apart.
If your intent is to disinfect water with ozone, the use of an ORP
(oxidation reduction potential) meter is recommended to control the
dosing of ozone into the water. The water should also be run through a
carbon filter before use, so your not dumping a bunch of nasty little Os
down your throat.

a few years ago i remember reading in a water journal about a system
being used in remote villages in ?africa that consisted of a plexi
(r) box with uncoated fluorescent tubes mounted over it that would uv
sterilize the water.  i think it ran off a solar panel and auto
battery.  i didnt save the reference much to my regret.  i do
remember they emphasized that the tubes were uncoated.

http://www.lifewater.org might know something.

This would be UV sterilization rather than Ozone. Glass will absorb UV-C
radiations and quartz must be used.
Here, UV-C is used to tear apart the nucleus of cells. Thereby
alterering the genetic structure of bacteria and Killing it.

As for the dryer. The air dryer maximizes the efficiency of ozone
production. Only some of the O2 molecules are split, and only some of
them combine to form O3. Drying the air helps this reaction.
The little ozone generator I'm using is advertised as not needing an air
dryer so I'm not using one and it works great. It's the corona discharge
type with the little lamp inside.
