Product IntroductionTHEORY-Guangpu Guichuan-

The secondary water supply ultraviolet sterilization equipment is a device used for sterilization and disinfection of secondary water supply in residential areas, schools, office buildings, and other places.

Sterilization principleTHEORY-Guangpu Guichuan-

Ultraviolet disinfection is carried out by irradiating water with ultraviolet light, which is a photochemical process and a physical disinfection method. Among the ultraviolet wavelengths, UV-C is the wavelength range with the best bactericidal effect. The bactericidal effect of UV-C depends on the dose of ultraviolet light, which in turn depends on the intensity and irradiation time of UV-C, i.e. D=I × S, where D is the dose, I is the intensity, and S is the irradiation time.
The principle of sterilization is to use the energy of ultraviolet photons to destroy the DNA structure of various viruses, bacteria, and other pathogens in water, causing them to lose their ability to replicate and reproduce, achieving the effect of sterilization.

Sterilizing EffectEFFECT-Guangpu Guichuan-

The bactericidal effect of ultraviolet radiation depends on the product of the radiation intensity and irradiation time of ultraviolet radiation, that is, the irradiation dose, measured in mJ/cm2.UV sterilization equipment for secondary water supply of tap waterIt has a good inactivation effect on most bacteria, viruses, and protozoa. For most common microorganisms in water bodies, as well as chlorine resistant Cryptosporidium and Giardia, the dose of ultraviolet radiation for their 4log inactivation is within 10mJ/cm2. However, some viruses have strong resistance to ultraviolet radiation. For example, adenovirus requires a higher dose to achieve a 4log inactivation rate. However, recent studies have shown that medium voltage ultraviolet and pulsed ultraviolet can more effectively inactivate adenovirus. UV sterilization equipment does not produce harmful by-products during the sterilization process, making it reliable and reassuring.
