Ozone disinfection
Ozone disinfection has strong oxidizing properties, and has significant sterilization, disinfection, and pesticide degradation effects. It is an efficient and broad-spectrum bactericide. Ozone gas can also kill hepatitis viruses, cold viruses, etc. Ozone spreads quickly and evenly in the air, disinfecting without dead ends. Its disadvantages: the sterilization time is longer, generally should reach 50-60min; in addition, if there is water on the surface of the items to be disinfected, the effect of ozone disinfection will be weakened.
UV disinfection
UV can kill a variety of microorganisms, such as bacterial propagules, spores, mycobacteria, viruses, fungi, rickettsiae, mycoplasma, etc., with broad-spectrum characteristics.
Most of the products on the ordinary market use 20W ultraviolet lamps (radiation intensity should not be less than 70μW/cm2), and the disinfection time is generally designed between 20~50min, which can kill most bacteria well. Its shortcomings are: ultraviolet rays can only travel in a straight line, low radiation energy, weak penetrating power, and can only kill directly irradiated microorganisms. Therefore, the disinfected parts should be fully exposed to ultraviolet rays when disinfecting.
Which is better, ozone disinfection or ultraviolet disinfection?
In fact, ultraviolet disinfection and ozone disinfection have their own characteristics. Ozone disinfection has a strong oxidizing effect. Like ultraviolet disinfection, it does not produce excess by-products. By oxidizing the enzymes in bacteria, it destroys the metabolism of bacteria and eventually leads to death. . Ozone gas itself is a gas, which can fill the entire space without dead ends. However, ozone disinfection is the same as ultraviolet disinfection, and the sterilization penetration ability is not strong. To achieve the best results, it takes about 30-60 minutes, otherwise it will not be thorough enough, and various fungi and pathogens will be revived in a short time. After the sterilizer is turned off, it must be sealed for 30 minutes, so that the effect will be the best.
