The killing or inactivation of human-disease-causing microorganisms or pathogens
is a process capable of destroying pathogenic microorganisms but, as ordinarily used, not bacterial spores
effective killing by chemical or physical processes of all organisms capable of causing infectious disease Chlorination is the disinfection method commonly employed in sewage-treatment processes
a cleaning process which destroys most microorganisms, but not highly resistant forms such as bacterial and mycotic spores
The treatment of water to inactivate, destroy and/or remove bacteria and other microorganisms from it Chlorine, ultraviolet light and ozone are often used for this purpose
Trevira CS fabrics may be disinfected using any of the usual methods as listed in the Federal Health Act ("Bundesgesundheitsblatt") para 10 of the Federal Legislation on Disease ("Bundesseuchengesetz") This a great advantage over textiles given a finish with flame-retardant agents as the finish is damaged by the disinfection treatment
Treatment of objects or surfaces to remove or inactivate organisms such as vegetative bacteria, viruses and fungi, but not spores Disinfection can be achieved by heat, by immersion in boiling water or by applying certain antiseptics
the killing of the larger portion of the harmful and objectionable bacteria in the sewage Usually accomplished by introduction of chlorine, but more and more facilities are using exposure to ultraviolet radiation, which renders the bacteria sterile
Inactivation (killing) of pathogens or organisms, capable of causing infectious disease, by chemical or physical processes
A process in which pathogenic (disease producing bacteria) are killed; may involve disinfecting agents such as chlorine, or physical processes such as heating
Killing of infectious agents outside the body by direct exposure to chemical or physical agents High-level disinfection may kill all microorganisms with the exception of high numbers of bacterial spores; it requires extended exposure to ensure killing of most bacterial spores It is achieved, after thorough detergent cleaning, by exposure to specific concentrations of certain disinfectants (e g , 2% glutaraldehyde, 6% stabilized hydrogen peroxide and up to 1% peracetic acid) for at least 20 minutes Intermediate-level disinfection does not kill spores; it can be achieved by pasteurization (75 deg C [167 deg F ] for 30 minutes) or by appropriate treatment with EPA-approved disinfectants
The treatment of water to inactivate, destroy, and/or remove pathogenic bacteria, viruses, protozoa, and other parasites
A process by which viable biohazardous agents are reduced to a level unlikely to produce disease in healthy people, plants or animals
A process in which pathogenic (disease-producing) bacteria are killed; may involve disinfecting agents such as chlorine, or physical processes such as heating
