Ozone Emission Sources. Emissions contributing to ozone formation come from many areas. The main emission sources categories are: On-road - cars, trucks, and buses. Off-road - aircraft, locomotive,etc. Non-road - construction, agricultural equipment, etc. Point - cement and power plants.
Others use ultraviolet lights (UV method) to produce Ozone. Generally, the UV Ozone systems produce a lower concentration of Ozone. Since concentration of Ozone is important, most applications will use Corona Discharge Ozone generators. Since Ozone cannot be stored, it is used as quickly as it is produced.
