My hot tub has an ozonator in it, the device is nothing more than a quartz UV germicidal lamp and ballast mounted in an aluminum box with a barbed hose fitting on it. It runs during the filtration cycle and the ozone is drawn into the water with a venturi. The stuff is toxic, but dissipates and breaks down quickly.

It's difficult to make in quantity, that device is *very* inefficient. 
It's just as well, it would make you rather ill, otherwise.
