Ozone generator are highly effective for water purification and food sterilization. They break down contaminants in water, remove harmful pesticides, bacteria, and chemicals from most fruits and vegetables, and eliminate residual antibiotics and hormones in meats.
Ozone Formation and Measurement
Ozone often forms in nature under conditions where O2 does not react. In industry, ozone is measured in g/Nm³ or weight percent. Applied concentrations range from 1 to 5 weight percent in air and 6 to 13 weight percent in oxygen.
Corona Discharge Ozone Generator
Corona discharge ozone generators are popular for industrial and personal uses. They work using a corona discharge tube and are cost-effective, requiring only ambient air. However, they produce nitrogen oxides as a by-product. An air dryer can reduce nitric acid formation by removing water vapor and increasing ozone production. An oxygen concentrator can further enhance ozone production and minimize the risk of nitric acid formation by removing both water vapor and nitrogen.
Ultraviolet Light UV Ozone Generators
UV ozone generators use a light source that generates narrow-band ultraviolet light, similar to the ozone layer in the Earth’s stratosphere. These generators are less expensive but produce ozone at concentrations of about 2% or lower. A significant disadvantage is the need for prolonged exposure to the UV source. This makes them impractical for rapidly moving air or water streams, such as in-duct air sterilization.
Cold Plasma Ozone Generators
Cold plasma ozone generators expose pure oxygen gas to a plasma created by dielectric barrier discharge. This method splits diatomic oxygen into single atoms, which then recombine to form ozone. Cold plasma machines produce higher quantities of ozone compared to UV generators, with a maximum concentration of about 5%. Despite their efficiency, they are expensive and require maintenance, making them less common. These units use a dielectric insulator to separate metallic electrodes and prevent arcing. Some cold plasma units can produce short-lived allotropes of oxygen, such as O4, O5, O6, and O7, which are even more reactive than O3.
