The disinfection and sterilization advantages of ozone generators

The sterilization effect of ozone is most ideal under humidity conditions of 70-80%, and the effect is poor when the humidity is below 45%. Therefore, in general use, especially in sterile rooms and wards in pharmaceutical workshops, attention should be paid to appropriately increasing humidity in the environment. Ozone generators used for air disinfection mostly use ceramic high-frequency discharge mode, which has the advantages of simple structure, reliable performance, low operating cost, and flexible adjustment.

The disinfection and sterilization advantages of ozone generators:

(1) Efficiency: Ozone generator disinfection does not require any other auxiliary materials or additives. During disinfection, the ozone generator generates a certain amount of ozone, which diffuses evenly, is inclusive, and has good permeability in a relatively sealed environment. It overcomes the problem of disinfection blind spots in ultraviolet lamp tube sterilization and achieves comprehensive, rapid, and efficient disinfection and sterilization. In addition, due to its broad-spectrum sterilization, it can kill various microorganisms such as bacterial reproductive bodies, spores, viruses, fungi, and protozoan spores, as well as destroy Clostridium botulinum, toxins, and rickettsia. At the same time, it also has strong functions in removing mold, fishy, and odorous odors.

(2) High cleanliness: Ozone can naturally decompose into oxygen in the environment, which is the unique advantage of ozone as a disinfectant. Ozone is produced by utilizing oxygen in the air. During the disinfection and oxidation process, excess oxygen atoms (O) combine to form molecular oxygen (O2) after 30 minutes, without any residual substances. This solves the problem of secondary pollution of residues during disinfectant disinfection and eliminates the need for cleaning again after disinfection.

(3) Convenience: Ozone sterilization equipment is generally installed indoors or in central air conditioning systems, air purification systems, or sterilization equipment (such as ozone disinfection and sterilization cabinets, transfer windows, etc.). The timed control of ozone sterilization equipment can be automatically set according to the required concentration and time for sterilization, making it easy to operate and use. Formaldehyde and epoxy acetic acid fumigation disinfection take a long time, while ozone disinfection can be started and used at regular intervals every day.

(4) Economy: Through the application of ozone disinfection and sterilization in many pharmaceutical industry GMP, as well as the comparison of its use and operation in medical and health units, ozone disinfection method has significant economic and social benefits compared to other methods.

The safety of ozone air disinfection. Ozone safety has been extensively tested in animal and human experiments, with the main exposure route being inhalation. Continuous and long-term inhalation tests have shown that ozone is not carcinogenic (NTP, 1995); However, it has a significant stimulating effect on the respiratory system of animals and humans, and can affect respiratory function in exposed environments. So, we suggest using ozone to disinfect the air, which should be done in an unmanned environment. Personnel can only enter after half an hour of disinfection is completed.
