Principle of Sterilization, Usage Characteristics, and Application Fields of Immersed UV Sterilizers

Ultraviolet sterilizer The sterilization principle of these devices primarily relies on the irradiance intensity emitted by the UV lamp—specifically, the irradiance intensity radiated by the UV sterilization lamp, which is inversely proportional to the distance between the lamp and the object being disinfected. Therefore, once the irradiance reaches a certain level, the disinfectant object will need to remain under irradiation for a relatively longer period. The closer the object is to the UV lamp, the better the sterilization effect will be; conversely, the farther away it is, the less effective the sterilization will be. So, what exactly are the sterilization principles and operational characteristics of immersion-type UV sterilizers? Let’s explore this together below!

 

I. Principle of Ultraviolet Disinfection:

 

After absorbing ultraviolet light, microorganisms cause certain changes in the nucleoprotein molecular structure within their own cells, leading to protein denaturation. DNA The break on the chain, and it's also damaged. DNA Crosslinking within the molecule, as well as hydration reactions occurring on cytosine and uracil, have even been observed on dimers formed on adenine. Since these dimers disrupt the normal base pairing between purines and pyrimidines, they consequently induce changes. DNA biological activity. As a result, it disrupts microbial metabolism, inhibiting their proliferation and cell production, and causing destructive effects. It also interferes with the synthesis of proteins and enzymes within microbial cells, leading to structural and functional alterations and damage, ultimately resulting in microbial death and achieving the purpose of disinfection and sterilization. Experiments have demonstrated that ultraviolet light at wavelengths of... 240nm To 280nm The range exhibits the strongest antibacterial efficacy, especially at wavelengths in... 253.7 At the micrometer level, ultraviolet light exhibits its best sterilizing effect. This is because within the ultraviolet spectrum, a certain wavelength range... C Ultraviolet light is highly effective at destroying bacteria and viruses that are harmful to human health. Since ultraviolet light can kill microorganisms such as bacteria, molds, viruses, and single-celled algae, it has become the preferred equipment for disinfection and sterilization in the water treatment industry.

 

Ultraviolet light is a type of electromagnetic wave. , When electrons in an atom jump from a higher energy level to a lower energy level, , Excess energy will be released in the form of electromagnetic waves. The stronger the energy of the electromagnetic wave, , The shorter the wavelength, , Wavelengths visible to the human eye 400 nm – 780 nm (1 nm = 10⁻⁹ m), To the naked eye ,400 nm The electromagnetic waves are displayed in blue and purple. ,780 nm The electromagnetic waves are displayed in orange and red. Ultraviolet refers to wavelengths shorter than... 400nm Short electromagnetic waves , Because its spectrum lies beyond the violet region. , Hence the name ultraviolet. ultraviolet, Abbreviation uv) Ultraviolet radiation generally refers to wavelengths in the range of 100-400nm electromagnetic waves , The human eye cannot see ultraviolet light.

 

II. Characteristics of Immersed UV Sterilizers:

 

1 Seawater, freshwater, or other bodies of water treated by an ultraviolet water disinfection system can achieve removal rates of various viruses and bacteria as high as... 99.99% Above, the cost per ton of water treatment is 4 To this point 1 Split the money in RMB (depending on how clean the water body is).

2 Accelerate the growth rate of aquaculture populations, enhance the health of both juvenile and adult aquaculture organisms, and produce healthy juveniles and healthy adults.

3 Without altering the original ingredients, flavor, or color of various beverages and other liquid foods, the removal rate of pathogenic organisms such as bacteria can reach... 99.99% The above.

4 Before disinfecting swimming pool water with ultraviolet light, the chlorine level in the water can be reduced to: 0.5 Milligram / Removal rate for viruses and bacteria: 99.99% The above.

5 Adding ultraviolet disinfection to the end-use water supply can meet the standards for direct potable use.

6 Disinfection of municipal wastewater reduces the total bacterial count to: 200 one /100ml The following is Escherichia coli. 20 one /100ml The following: Biological death is achieved, thereby attaining the purpose of disinfection and sterilization.

 

Fast disinfection speed , High work efficiency , Does not alter the physical or chemical properties of water. , Does not increase the odor or taste of water. , Unlike other disinfection methods that involve adding disinfectants to water, , It will generate secondary pollutants. The device is easy to operate. , Easy to manage , Reduce workers' physical labor. , It promotes safe production. The immersion-type UV sterilizer can effectively act on both the liquid in the tank and any residual air. , Can effectively prevent secondary pollution. , Maintain the cleanliness of the water tank. , This type of sterilizer is suitable for industries that require segmented and timed water supply, such as differentiated water supply systems, electronics, pharmaceuticals, food, cosmetics, and others. Products in this series feature high waterproof performance and are easy to install. , High sterilization rate and other excellent characteristics.

 

 

Three, Advantages of Immersed UV Sterilizers

 

Immersive UV sterilizers versus flow-through types , The immersion-type structure is simple. The UV sterilization lamp is placed directly into the water. , This method can be applied to flowing, dynamic water. , It can also be used in static water. With this treatment method, it’s important to note that the lamp tube could potentially break due to accidental circumstances. ; Long-term processing , The surface of the lamp tube will be covered by pollutants such as algae in the water. , Will severely affect the transmission of ultraviolet rays. Disinfecting water bodies for different types of objects. , The key is to understand changes in water quality and the water’s transmittance of ultraviolet light. Immersed UV sterilizers can destroy microorganisms. DNA and designed based on the principle of causing death , Use a high-purity quartz tube as the casing. , Comes with a high-performance quartz ultraviolet low-pressure mercury disinfection lamp tube. , Has strong bactericidal power , Long lifespan, stable and reliable branch operations, and other advantages. , It can effectively act on both the liquid in the tank and any residual air. , Can effectively prevent secondary pollution. , Maintain the cleanliness of the water tank. , This type of sterilizer is suitable for industries that require segmented and timed water supply, such as differentiated water supply systems, electronics, pharmaceuticals, food, cosmetics, and others. Products in this series feature a simple structure, low cost, and easy installation. , Its bactericidal efficiency ≥ 99%, Ultraviolet lamp lifespan ≥ 9000 Hour.
