Methods of Ozone Generation
In recent years, ozone is more and mroe used in many applications . Many have tried to sell ozone as a one size fits all solution, solving all problems and completely eliminating hot water and chemical usage. But do you have any idea about the generation of ozone? How is it produced? Generally speaking, ozone can be generated through three methods.The commonly available ozone systems on market use one of three different techniques to generate ozone:• Coronal Discharge
• Ultraviolet Radiation
Coronal Discharge generates ozone through use of a high voltage spark using dry air and pure oxygen.The main advantages of this type of generation are the maturity and efficiency of the technology. However, the disadvantages include unavoidable nitrogen oxide byproducts (NO and NOx), additional dehumidification is required, oxygen concentrators or pure oxygen source is required, and this method has a high initial expense and expensive replacement parts.
Ultraviolet Radiation (UV) generates ozone using UV lights (black lights) and dry air. Its main advantages are its low cost, no Nitrogen Oxides are generated, it is not affected by humidity, and its low cost. Its disadvantages include very low concentrations of ozone are generated, it consumes more electricity than other methods, and periodic bulb replacements are costly and time consuming.
Electrolytic ozone generation makes ozone through electrolysis. Direct Current (DC) is passed through pure water, breaking the water into hydrogen and oxygen. The main advantages are low cost, low voltage DC is used, it is not affected by humidity, and high concentrations of ozone are generated with very little off gassing. Disadvantages include periodic consumable replacement (3 years) and power must be applied at all times.
