Why We Choose Ultraviolet?
Ultraviolet (UV) light is widely used nowadays in many disinfection applications, such as food, air and water purification. Used at sufficiently short wavelength, the UV light is harmful to microorganisms. Therefore it is efficient in destroying these organisms’ DNA and leaving their un-functional cell behind. Normally the natural UV light is blocked by atmosphere. However, a UV light device can make the water or air system circulate and disinfect microorganisms such as pathogens, virus, spores and molds. This application of disinfection has been practiced firstly in medical sanitization back to mid-20th century. Then the application has been expanded to water and air sanitization.
UV treatment for disinfection has its advantages in the following respects.
1.Efficient: comparing to disinfect material in boiling water, UV treatment requires less labor and less energy. UV treatment is rapid and efficient.
2.Safe: unlike Chlorine disinfection, UV treatment leaves NO residual after the disinfection. Invented based on natural sunlight, UV treatment does NO harm to human being.
3.Simple: to operate UV treatment requires minimum special training, because it creates no potential hazardous materials during and after the treatment.
UV treatment is used in the following applications.
1.Air Sterilization: especially in hospital, to control air quality, the UV light purifies the air from microorganisms that cause illness and contaminants which can be crucial to asthma or other respiratory symptoms.
2.Surface Sterilization: UV light disinfects surfaces without chemicals, and it can kill viruses, bacteria, yeast, and fungi in seconds, which are two crucial criteria for filling equipment, conveyor belts, transport containers and working surfaces of food products.
3.Water Disinfection: UV light is used to create safe water include waste water, drinking water, and public water facilities. UV water treatment is safe and environmentally friendly, and, in many cases, more effective.
4.Other such as Food Processing, Clean Room, Life Science and of course cleaning mattresses
