The meaning of Ozone

Ozone is a form of oxygen that has three atoms per molecule rather than two atoms found in oxygen; it decomposes quickly and turns into regular oxygen? It was discovered in 1840 by Christian Friedrich Schonbein.
There are basically two methods of producing ozone…ultra-violet and corona discharge. Most equipment uses the corona discharge method, simulating in essence, lightning. Equipment utilizing UV was hard to find in the past because it was inefficient, expensive to operate, unreliable, and very costly to service compared to the corona discharge equipment available. In recent years the UV technology has improved enough to make it a viable alternative to the corona discharge systems.
