Every customer will be faced with the choice of UV sterilizer model before purchasing the UV sterilizer. Most of the time, the choice of UV sterilizer model is not a single factor, but a comprehensive consideration. What should be paid attention to in use? The manufacturer of the open channel ultraviolet sterilizer has made a detailed introduction

1. Water quality When selecting an appropriate UV system or determining whether UV disinfection is completely feasible or appropriate, the quality and nature of the water to be disinfected are important factors to be considered.

2. Water flow is the key factor to determine the effectiveness of UVB in inactivating specific pathogens. Exposure time is the time between which pathogens are exposed to a specific intensity of UVB. The longer the exposure time, the more short wave ultraviolet rays will penetrate the pathogen cells, thus making the inactivation process more effective. The slower the water flows through the UV system, the longer the UV connection touch time, and vice versa; Therefore, the water flow of Z large and Z small shall be considered.

3. Different pathogens that need to be inactivated have different resistance to ultraviolet radiation, and some pathogens are more vulnerable than others; Therefore, in order to inactivate different pathogens, different pathogens need different amounts of exposure to UV waves. Ultraviolet disinfectants are widely used and have high application value in water treatment. It is used to destroy and change the DNA structure of microorganisms through ultraviolet radiation, so that the dead or sterile offspring of bacteria can achieve the purpose of sterilization. The real bactericidal effect is UVC ultraviolet light, because C-band ultraviolet light is easily absorbed by the DNA of organisms, especially 253.7nm ultraviolet light.
