Ozone, also known as trioxygen, has the chemical formula O3 and is composed of three oxygen atoms. Ozone gas is naturally unstable at normal atmospheric conditions which means that in commercial applications, ozone must be made on-site using an ozone generator. The lifetime of ozone in water depends on various factors including water temperature, ozone concentration, and the composition of the water itself. Ozone is one of the most power oxidation tools water treatment professionals have for purification and disinfection.
Commercial Ozone Production from Electrical Discharge
The most common method of producing ozone commercially and industrially is electrical discharge, or corona discharge. A corona discharge is simply a diffused spark through a dielectric to spread out that electrical discharge to a large area for maximum efficiency.

There are many types and styles of corona discharge ozone generators. These go by many names, but are fundamentally the same, using these components:

  Corona cell using a dielectric
 Dielectric material may be glass, ceramic, or quartz
Dielectric may be conical, or flat plate
High voltage transformer to increase voltage of the electrical discharge
Power supply to regulate power to transformer 50Hz machines will only regulate the voltage to the transformer
High frequency machines (greater than 50 Hz) will regulate frequency and/or voltage to transformer

Advantages of DeBru Corona Discharge Ozone Generator

  • Scalable and can create very large amounts of ozone
  • Creates ozone at medium to high ozone concentrations (8-12% W/W)
  • Cost effective for long term operation
  • Low maintenance
  • Disadvantages of Corona Discharge Ozone Generator


  •   High cost for initial capital investment
  • Creates excess heat that must be removed for efficient operation
  • Requires very clean, dry air/oxygen feed-gas for reliable operation
