What's the difference between the biological clean room disinfection and sterilization?
Disinfection and sterilization are two different concepts. Of biological clean room disinfection and sterilization methods were compared, the uv and ozone disinfection sterilization, formaldehyde three commonly used ways to do in this paper.
According to the data, the human body about every 6 ~ 7 cm2 skin with 1 ~ 10000 bacteria, of which about 1% of pathogenicity, breathing and speech also will send out bacteria.
Obviously, the clean workshop especially relatively clean to demand higher biological clean room, prevent bacteria, remove and destroy bacteria is very important.
Disinfection and sterilization, is to remove and destroy bacteria, two kinds of effective methods to biological cleanroom microbial requirements.
2. The disinfection and sterilization are two different concepts
Disinfection and sterilization are two different concepts.
Alleged sterilization, it is kill or remove the material of all the microbes (including bacteria, viruses, etc.), has the absolute significance. That is to say, corresponding to the sterilization is not sterilization, there is no intermediate state of sterilization more with less. From that point of view, the absolute sterilization due to its hard to achieve or attain infinite long and almost non-existent.
So-called disinfection, killing most of the pathogenic microorganisms, or reduced to a certain degree of processing mode, in the process, some bacteria or virus due to thermal or efficacy of the drug resistance and not damaged, has the relative significance. That is to say, the disinfectant itself has a certain scope of sterilization.
It is not hard to see, here on disinfection and sterilization of the relative and absolute meaning understanding, are different from our usual understanding. What we usually call "sterilization", accurately should be called "sterilization".
