Swimming pool ozone generators
Swimming pool ozone generators. I've been interested in ozonolysis reactions ever since I first read about them. I noticed that ozone is used as a
substitute for chlorine for sterilising swimming pools:

I wonder if these would be of use in the lab. They are designed to work in water but I'm sure they can be adapted so that they can produce ozone in
other solvents. Since they are used to sterilise pools, they must produce very large quantities of ozone so they would be useful for producing bulk
quantities of ketones from alkenes.

Don't bet on it . . .
Ozone generators are notoriously inefficient; manufactures claims aren't to be trusted and if the air-feed is less than anhydrous,
NO<sub>2</sub> and N<sub>2</sub>O<sub>5</sub> will be formed in addition to ozone!

My guess is those pool ozone generators are also making plenty of nitric acid (very dilute of course). I would question whether all those nitrates
could lead to environmental pollution when the water gets drained (no more than all the chlorine from conventional pools I suppose).

I don't think that nitrates pollute the environment. They are good fertilizers 
I like the idea of ozonisation instead of chlorination, because swimmers can be allergic to chlorine, and people who spend a lot of time in
chlorinated pools are known to have damaged lungs to some extent.

Nitrogen oxides require high temperature to form as in an electric arc.
Corona discharge for generating ozone is at most warm to the touch
and several orders of magnitude below the energy necessary to break
the nitrogen triple bond.

Can you cite some analysis of the effluent stream from any given device.
The governing authority on this does not observe such a possiblity.

You didn't search hard enough . . . ?
