HOW IS OZONE PRODUCED?
Ozone can be produced artificially according the same principle as it occurs in nature, which means by UV light (ozone layer) or via corona-discharge (high voltages, thunderstorm). In both methods the connection between the oxygen molecules is broken up. Consequently oxygen radicals are produced, which connect with the oxygen molecule to O3 (ozone). For the production of ozone, corona discharge is used more because of the greater advantages of this method. Advantages are the lower costs for ozone production (more cost-efficient) and the greater durability of the system. For the feed inlet ambient air can be used as well as pure oxygen. For pure oxygen, oxygen generators can be used to concentrate oxygen out of air. When pure oxygen is used a higher concentration of ozone can be produced.
Ozone is produced by exciting oxygen molecules in a silent corona discharge by passing an electrical current across a dielectric gap. Ozone may be produced from either air or oxygen. Air-based generators can only produce up to 2-3% ozone. Oxygen based generators can produce much higher concentrations, typically 6-14% but for some small specialized applications up to 22%. How can ozone be harmful and beneficial, it seems to be a Paradox? Ozone is hazardous. It is harmful to man when formed in smog. Yet, the Ozone Layer in the upper atmosphere protects the earth from harmful ultraviolet rays which would cause skin cancer epidemics. Moreover, it can be used to disinfect drinking water and for a host of industrial uses. Who owns Praxair Trailigaz Ozone Company?
