同傍大学 Tongji University ●Ozone Generation Because ozone is chemically unstable,it decomposes to oxygen very rapidly after generation.It must be generated onsite. The most efficient method of producing ozone today is by electrical discharge.Ozone is generated from either air or high-purity oxygen when a high voltage is applied across the gap of narrowly spaced electrodes.(Fig.11-8). The high-energy corona created by this arrangement dissociates one oxygen molecules,which re-forms with two other oxygen molecules to create two ozone molecules.Tongji University  Ozone Generation Because ozone is chemically unstable, it decomposes to oxygen very rapidly after generation.

Ozone rate: 1-3% for air; 3-10% for pure oxygen by weight
