When air is used as the feed gas for an ozone generator, what is required?

When considering the requirements for using air as the feed gas in an ozone generator, extremely dry air is essential. This is because moisture can interfere with the ozone generation process. Ozone generators typically produce ozone by applying a high voltage to oxygen molecules, causing them to split and recombine into ozone (O3).

When there is excessive humidity in the air, water molecules can compete with oxygen molecules for the electrical energy needed for ozone production. This can lead to a reduced efficiency in generating ozone and may result in lower quality ozone, which is critical for applications such as water treatment.

In addition, high levels of humidity can cause corrosion or other issues in the equipment used for ozone generation. Hence, maintaining a dry air supply ensures the generator operates effectively while preventing unwanted side effects related to moisture. Therefore, using extremely dry air is the correct choice for maximizing ozone output and maintaining equipment longevity.
