The Difference Of Ozone Generator And UV Lamp Sterilization Effect

- Aug 31, 2019-

Ozone generator and UV sterilization are one of the commonly used sterilization methods. What is the difference between ozone sterilization and UV disinfection in the application? The ozone generator uses ozone disinfection and UV disinfection.

Advantages 1. Ozone is more thorough than UV disinfection 

Ozone penetrates everywhere, no dead ends. When ultraviolet rays are irradiated onto the surface of the object and a certain level of irradiation intensity is reached, the ultraviolet rays have only a bactericidal action. Food workshops are often high, resulting in insufficient UV radiation intensity, especially at long distances, and the illumination creates large dead spaces. Ozone is a kind of gas with strong permeability, good diffusivity, uniform concentration, and no dead angle.

Advantage 2. Using ozone to kill faster than UV lamp

UV irradiation sterilization requires a long time, generally more than 6 hours of irradiation, ozone that meets the standard concentration only needs to be turned on for more than 1 hour;

Advantage 3. Ozone is better than UV disinfection under high humidity 

When the relative humidity of the environment reaches 60% or higher, the disinfection effect drops sharply. When the humidity reaches 80% or higher, the bacteria can be revived. The ozone situation is just the opposite. The higher the humidity, the better the sterilization effect. This is due to the thinning of the cell membrane and the destruction of its structure by ozone under high humidity. This feature is particularly suitable for high humidity environments prevalent in the food industry;

Advantage 4. Low concentration ozone can be disinfected on-site, but UV is not allowed.

When irradiated with UV lamp, the workers must leave the workshop. After the irradiation is completed, low-power UV sterilizers cannot be used for cleaning. When the ozone is sterilized, the production personnel must leave the site. After disinfection is completed, the amount of ozone can be reduced, and low-concentration ozone that meets national health standards can be used. Continue to keep the air in the production workshop clean. Ozone is a green, clean disinfection method. It has no residue, does not cause secondary pollution to food, and turns into oxygen after decomposition. This is a good food production and disinfection.
