Product Details

Ultraviolet disinfection principle

Ultraviolet (UV) radiation is categorized into four types—UV-A (320-400nm), UV-B (275-320nm), UV-C (200-275nm), and vacuum ultraviolet—based on variations in their biological impacts.In water treatment processes, only the UV-C segment of the ultraviolet spectrum is utilized. Within this specific UV-C range, ultraviolet rays with a wavelength around 260nm have been verified to deliver the highest sterilization effectiveness.

The Guanyu ultraviolet disinfection device combines multiple scientific disciplines, including optics, microbiology, mechanics, chemistry, electronics, and fluid mechanics. It works by using a specially engineered, high-efficiency, high-intensity, and long-lasting UV-C light source to emit intense UV-C radiation. This radiation is then directed at water as it flows through the device.

Advantages

High Sterilization Efficiency

Ultraviolet disinfection typically eliminates 99% to 99.9% of bacteria and viruses within just one to two seconds.

Wide Sterilization Spectrum

Ultraviolet disinfection boasts the broadest sterilization spectrum available today, and it delivers highly effective killing power against nearly all types of bacteria and viruses.

No secondary pollution

Ultraviolet sterilization operates without the need for adding any chemical agents. This means it won’t introduce secondary pollution to the water body or the surrounding environment, nor will it alter any components present in the water.

Safe and Eco-Friendly

Unlike traditional disinfection methods like chlorination or ozonation—where the disinfectants themselves are highly toxic and flammable—the ultraviolet disinfection system is free from such safety risks.

Economical

Ultraviolet disinfection equipment occupies little space, is simple to install, and comes with low operating costs and a small total investment. Its running expenses are half that of chlorine disinfection.

Factors affecting the effect of UV sterilization

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.
