There are three main ozone generation methods:

Corona Discharge: The most widely used industrial technology. High‑voltage electric field converts dry oxygen or air into ozone. High output for water treatment projects.

UV Lamp Method: 185 nm ultraviolet radiation decomposes oxygen molecules to produce ozone. Low output, mainly for small‑size air disinfection.

Electrolytic Method: Produce ozone by electrolyzing pure water. No external gas source required, limited capacity for small high‑purity water applications.
