UV lamps vs corona discharge...

[KILOWATT]

Hi everyones...thanks for your time. I wish to make a large ozone generator
and i'm wondering if one of those two methods (see subject line) produces
less byproduct (like nitrous oxyde) than the other ? Maybe i'm wrong and
pure oxygen MUST be used to not have any byproducts...not shure. Any
comments? TIA for any replies.

I surely think that 184.9 nm UV produces more ozone and less NOx than
coronas, sparks/arcs, etc...

Do not confuse 184.9 nm, the shorter and secondary of the two main
shortwave UV wavelengths of a low pressure mercury discharge, with 253.7
nm which is the main one but basically useless for intentional ozone
generation. The main application of 253.7 nm is germicidal use.

Just be aware that ozone is a lung irritant and levels used to clean air
(for example) are a hazard to health. Very bad for you if you have asthma
etc. I believe it also effects some rubber and plastic insulation.

Yes. Ozone is absolute murder on rubber. And lungs.

Ozone is indeed a major cause of rubber deterioration. Latex is

especially affected.

Also be aware that if your ozone generator reaches 12% purity, it will
explode. :-((
You will indeed need pure oxygen for levels above a per cent or so.
