Ozone generators are a popular and well-known appliance used to help clean the air in your home. But have you ever stopped to wonder where this technology came from? In this blog post, we’ll take a look at the history of ozone generators and how they’ve evolved over the years. We’ll also discuss some of the key applications of ozone generators. Stay tuned!

After Christian Friedrich discovered Ozone in 1839, scientists and engineers began experimenting with a wide range of potential applications. A hundred years ago, for example, several water treatment facilities were employing Ozone to disinfect the drinking water, reducing the risk of harmful bacteria that can cause illness.

In 1857, Siemens invented the first industrial ozone generator, based on corona discharges. Two concentrical glass tubes were utilized; the outer tube was covered externally with tin and the inner tube internally by a layer of tin.

The annular area between the tubes was aerated with oxygen. This method was later enhanced by the use of circulating cooling fluids or oxygen gaps along the discharge air or O2 gap, resulting in lower generation temperatures and less thermal damage to the ozone.

Development of Ozone in Various Applications


Ozone generation techniques and new ozone applications have grown in popularity because of technological progress during the previous two decades.

In particular, these include Water treatment ( waste water, cooling tower circuits ,drinking water,) Environmental protection (contaminated ground water treatment, improvement of biodegradability of waste waters…), Food industries (sterilization, bottle rinsing, disinfection, …) Gas treatment (deodorization, exhaust gas oxidation), Chemical industry (pure oxidizing reactions) and Chlorine free technologies are fields of applications which caused a higher demand for Ozone.

We have seen a drastic change in ozone generators and the way they are being used. From hospitals to your home, ozone generators can be found almost everywhere. With new technological advances being made each year, it will be interesting to see where ozone generators end up next.
