How it Works

How it Works

The two primary ways of producing ozone for water treatment are through the corona discharge or electrolytic process. The Ozonia CFS range uses proprietary Ozonia ceramic dielectric ozone generation technology to produce ozone using the corona discharge technique.

Ozone is the triatomic form of oxygen (O3). Ozone is generated by combining oxygen atoms (O) with oxygen molecules (O2). The corona discharge process takes place in an ozone generator in the gap between a high voltage electrode and an earth electrode. When high voltage is applied, a silent electrical discharge occurs in the gap. This discharge excites the oxygen molecules in the gas, which causes the oxygen molecules to split and combine with other oxygen molecules to form ozone.

As the pioneer of the ozone industry, our unique ability to deliver the most reliable and robust ozone systems is why thousands of customers around the world have chosen Ozonia. We have been the ozone industry leader for over 40 years. Trust Veolia to deliver the highest quality ozone solutions to meet your treatment challenges for small-to-medium-sized ozone water treatment applications.

Ozonia Ozone Systems

A typical ozone system includes five system components:

  1. Ozone Generator
  2. Feed Gas System
  3. Ozone Contactor
  4. Ozone Destructor
  5. Control System

The ozone generator is combined with an input gas system, usually air or oxygen, a contacting system such as a contact tank with ozone diffusers, and a vent ozone destructor to eliminate any trace ozone after the water treatment process. The control and automation system ties all the system components together and allows for automatic operation.
