If you have been doing some research on Ozone, you have no doubt already read many articles describing its characteristics. Really simple, it is 3 oxygen atoms that were combined through one of several processes. It becomes a very unstable molecule in this state, and is just waiting for a chance to stabilize again by oxidizing something, almost anything actually. 3′s a crowd right and as soon as our O3 molecule meets something, it uses that 3rd atom like a bomb to oxidize whatever it met.
What we want to do with the O3 we produce will play a big part in which process we use to make it. Here, we are concered with water, but Ozone also has many other uses. How we make the Ozone will determine how powerful it is. Then the biggest issue is how we will apply it. You can take the finest Ozone producing equipment available, and render it next to useless if it is not applied right. A few issues to be concerned with are concentration, solubility and contact time. There are the UV style Ozone generators (the bulb/lamp style) which do not use air preparation systems, and Corona Discharge (so called lighting storm style) ones that do. Although sometimes used without air prep. systems, CD style resonators should always use prepared air or oxygen to produce ozone. Humidity in the air will cause the process to create nitric acid which will destroy the generator in a short time. Humid air also produces very little ozone.
