There are many disinfection methods, such as ultraviolet disinfection and ozone disinfection. Next we will mainly describe the differences between ultraviolet disinfection and ozone disinfection.
The ozone generator is mainly used for the disinfection and sterilization of air, objects and water, as well as the sewage treatment. In addition, it has many other applications such as bleaching, deodorization, participation in industrial oxidation reactions, and diseases treatment. The working principle of ozone sterilization is that the ozone is used as a strong oxidant in a biochemical oxidation reaction during the sterilization process. Ozone can oxidize and decompose the enzymes necessary to oxidize glucose inside bacteria, causing the bacteria to die. Another way is to directly interact with bacteria and viruses, destroying their cell walls, DNA and RNA, and the metabolism of bacteria, leading to their death. Ozone can also penetrate into the cell membrane tissue of bacteria, invade lipoproteins and lipopolysaccharides inside the cell membrane that act on the outer membrane, causing the bacteria to undergo permeability distortion and dissolve and die.
Ozone sterilization is a kind of complete and broad-spectrum sterilization. It can kill bacterial propagules and spores, viruses, fungi, etc., and can destroy botulinum toxin. It not only has a strong killing effect on various bacteria, but also kills molds effectively. It is green sterilization method and causes no pollution. Ozone has poor stability and can quickly decompose into oxygen and single oxygen atoms by itself. A single oxygen atom can combine itself into oxygen molecules without producing any toxic residues, so ozone is called the cleanest disinfectant in the world. Moreover, ozone is a kind of gas, which can reach any location in the process of disinfection. Ozone can not only kill the virus directly, but also kill the pyrogen virus by killing the bacteria and microorganisms parasitized by the virus. Ozone water sterilizers and ozone water disinfectant are often used in ozone disinfection, which can improve the disinfection effect.
Although ozone disinfection is good, it also has restrictions. It can not be used in fields where there are flammable and explosive gases. The ozone generator should not be used in dusty places, places above 50°C or below -20°C, and places with high humidity after disinfection. All electronic products have this feature and cannot be used in high temperature and high humidity environments. Although our machines have undergone special treatment, to ensure our safety, we must try to avoid this situation.
Ultraviolet disinfection is characterized by being applied to disinfecting outside area above the processing line. Because ultraviolet light is a kind of light that cannot be turned, it is necessary to irradiate ultraviolet rays to more places as much as possible. The power of the UV disinfection light is generally 30 w/10 m2, the disadvantage is that the radiation intensity distribution is not uniform, the center is the strongest, and the intensity at the outside of the light end is attenuated significantly. The longer the irradiation distance, the weaker the intensity. The purpose of installing the ultraviolet disinfection light is mainly to disinfect the air and the operating table. Therefore, in order to better disinfect the operating table, it is most suitable to install the ultraviolet disinfection light 1 to 1.5 m away from the operating table. Ultraviolet rays are harmful to the human body. When doing ultraviolet disinfection, you should not be exposed to ultraviolet rays. It is best to set the switch in another place. Turn on the ultraviolet disinfection light after the personnel leave the disinfection room, turn off the ultraviolet disinfection light after the disinfection is over. After that, the personnel can enter the disinfection room.
Ozone disinfection has been widely used, and at the same time, the advantages of ozone water are being well recognized. Our company mainly produce ozone water treatment device such as ozone water filters, ozone water purifiers, etc. If you are interested in out products, please contact us.
