Water disinfection methods do not include autoclaving.
Water disinfection methods: UV ultraviolet disinfection.
Ultraviolet wavelengths used for disinfection are 254nm and 185nm, commonly used wavelengths around 254μm band of ultraviolet light on the purified water disinfection, it can reduce the rate of generation of new colonies of the water system, but for the plankton, it is only partially effective, through the irradiation, it kills microorganisms in the water is not more than 90% of the amount of microorganisms. Therefore, its penetration is poor, so its quartz tube should be cleaned regularly.
Water disinfection method: ozone disinfection method.
Ozone is a strong oxidant, in the water treatment system for deodorization, decolorization, sterilization, in addition to phenol, cyanide, iron, manganese and so on have obvious effect. Considering the residual problem of chemical methods of disinfection on the purified water system, ozone disinfection currently has more applications in the purified water units of domestic pharmaceutical factories.?
Halogenide is an effective disinfectant, but it is difficult to wash away from the water treatment system after use, and moreover, only in higher concentrations, such as up to a million molecules of 300, it can have an effect on the biofilm. But too high a concentration of disinfectants tend to produce corrosion of equipment, the use of both must weigh the pros and cons.
Water disinfection precautions:
1, according to the disinfection object to choose the appropriate disinfectant:
Different disinfection objects need to use different disinfectants. For example, in the disinfection of food processing plant, need to use the sanitation standard disinfectant; in the disinfection of medical equipment, need to use medical disinfectant.
2, choose a broad-spectrum bactericidal disinfectant:
With a broad-spectrum bactericidal disinfectant can effectively kill different kinds of bacteria, viruses and fungi. Common broad-spectrum germicidal disinfectants include bleach, hydrogen peroxide, acetaldehyde and so on.
3, consider the use of safe, environmentally friendly disinfectants:
When choosing a disinfectant, you need to consider its impact on the environment and human body. Some traditional disinfectants may have certain environmental and health risks, so consider using safer, more environmentally friendly disinfectants, such as ultraviolet disinfection, ozone disinfection and so on.
