1. How does ultraviolet light sterilize?

The principle of ultraviolet sterilization is to use ultraviolet photons with a wavelength of 100-400nm to irradiate microorganisms and various bacterial viruses to destroy the structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the body, causing them to die immediately or lose their ability to reproduce.

2. What are the applications of ultraviolet sterilization?

Ultraviolet sterilization technology is used in water, air, surface treatment, and many other industries, including UV curing. Application markets include Wastewater Recovery, Sewage Treatment, Water Reclamation, Municipal & Drinking Water, Semiconductor Ultrapure Water, Aquarium, Swimming Pool & Spa, Food & Beverage, Life Sciences, Healthcare, Food Processing, HVAC, Agriculture, Commercial Kitchen, waste gas treatment.

3. Why is ultraviolet radiation used in sterilization?

Green:

UV radiation does not require the use of chemicals to effectively protect the environment; toxic chemicals require specialized storage and handling, do not use such chemicals, and do not need to be concerned about excessive consumption and the resulting by-products.

Economic benefits:

Projects require less start-up capital and lower operating costs.

Efficient production:

UV radiation can treat objects directly without the need for storage tanks, long-term storage, or exposure.

High compatibility:

UV radiation is highly compatible with other water and air treatment equipment and does not cause changes in taste, odor, pH, conductivity, or chemical properties.

4. How can UVC lamps be used for air sterilization?

At present, there are two methods for air sterilization. One method is to directly irradiate the surface of the object with UVC lamps for sterilization; Clean air after killing. Such as air conditioning sterilization.

5. What are the advantages of UVC for air sterilization?

Ultraviolet rays with a wavelength of 254nm can effectively kill all kinds of influenza, viruses, bacteria, and other harmful microorganisms. It is recognized as a non-toxic, no harmful residue, and low-cost efficient sterilization method.

6. Can UVC ultraviolet rays kill the new coronavirus COVID-19?

The new coronavirus is a single-helix RNA (ribonucleic acid) virus. 254nm ultraviolet photons irradiate the new coronavirus, which can destroy its RNA structure and cause it to die immediately. Research shows that UVC irradiation can kill 99.99% of the new coronavirus.

7. Why is it so important to sterilize air conditioning and fresh air systems?

A large amount of dust and water vapor has accumulated in the air-conditioning system and ventilation ducts, which are breeding grounds for various viruses and bacteria. These bacteria and viruses are spread in different rooms through the flow of air, causing a huge and uncontrollable infectious disease pandemic, which has been confirmed by many bloody lessons. By adding a UVC ultraviolet sterilization system to the fresh air and air conditioning system (HVAC), bacteria and viruses can be effectively killed, and the unique photolysis effect of UVC wave light can be used to remove odors in the air.

8. How are UVC lamps used for water treatment?

The working principle of the ultraviolet sterilization system is to irradiate the flowing water with ultraviolet rays. Placing the UVC germicidal lamp in the cavity can sterilize within 1 second. UV radiation in the 254nm band at a dose of 30 mj/cm2 is sufficient to kill most aquatic microorganisms.

9. Are UVC rays harmful to the human body?

When the human body is irradiated by UVC exceeding a high intensity and time, it will cause harm to the human body. Long-distance short-term exposure will not cause harm to the human body. Strong UVC radiation can cause skin burns and eye discomfort. It is, therefore, necessary to avoid prolonged and high-intensity UV irradiation.
