Ultraviolet disinfection principle
According to the difference in its biological effects, ultraviolet rays can be divided into UV-A (320-400nm), UV-B (275-320nm), UV-C (200-275nm) and vacuum ultraviolet rays. In water treatment, the UV-C part of ultraviolet rays is actually used. In this band, the ultraviolet rays around 260nm have been proven to have the highest sterilization efficiency.
Guanyu ultraviolet disinfection device integrates comprehensive sciences such as optics, microbiology, mechanics, chemistry, electronics, and fluid mechanics. The strong ultraviolet UV-C light generated by the specially designed high-efficiency, high-intensity and long-life ultraviolet UV-C light generating device is used to irradiate the flowing water. When bacteria, viruses, etc. in the water are irradiated with a certain dose of ultraviolet UV-C light (wavelength 253.7nm). Its cell DNA and structure are destroyed, and cell regeneration cannot be carried out, thereby achieving water disinfection and purification. The spectrum with a wavelength of 185nm can also decompose organic molecules in water, generate hydrogen free radicals and oxidize organic molecules in water into carbon dioxide, so as to achieve the purpose of removing TOC.

UV transmittance (UVT)
The important factors affecting the effect of UV sterilization are the UV transmittance (UV transmission) of the sterilization medium (water) or the medium absorbance (absorbance). The transmittance of UV and the absorbance of the medium are affected by factors such as dissolved organic matter, inorganic matter and undissolved suspended matter in the water.
Total suspended particles (TSS)
The effect of suspended particles on the sterilization effect of UV is also very obvious. Suspended particles can absorb and reflect UV rays, thereby preventing UV rays from irradiating the DNA of bacteria and viruses. In addition, suspended particles will also accelerate the scaling and contamination of the quartz sleeve, thereby affecting the sterilization effect.
Particle size
The size of particles in the water has a great impact on the effect of UV sterilization, because large suspended particles will form shadows and dead corners for protecting bacteria and viruses. Usually, the effluent from the secondary sedimentation tank is more conducive to UV sterilization, and the average size of suspended particles in the water should be less than 30um.
Exposure time
The exposure time is related to the flow rate. When designing a UV system, it is generally designed according to the peak direct flow rate. The smaller the flow rate, the longer the exposure time, and the system has a greater effective dose.
