1. Quality of ultraviolet sterilizer

The lamp tube, quartz sleeve, ballast and other components of the ultraviolet sterilizer will affect the intensity of ultraviolet radiation in the water, thus affecting the sterilization effect of the ultraviolet sterilizer. The product adopts long life and stable ultraviolet lamp, high transmittance quartz sleeve, ballast with high and stable power factor and other components, which are important guarantees for the sterilization effect of the ultraviolet sterilizer.

In addition, the manufacturing process of the product will also affect the sterilization effect. The ultraviolet sterilizer needs to be designed and produced according to the relevant equipment production standards, and can be put into the market only after strict testing.

2. Water quality factors

If there are many suspended solids and particles in the treated water, the sterilization effect of ultraviolet radiation will be affected to a certain extent. Particles will shield target microorganisms and reduce the UV disinfection effect. Many studies have found that the killing effect of E. coli, Bacillus subtilis and other bacteria in the presence of particles is lower than that in the absence of particles. In addition, colloidal substances, iron and humic acid in the water body will affect the penetration rate of ultraviolet rays, thereby affecting the sterilization effect of the ultraviolet sterilizer on the water body.

In general, the factors that affect the disinfection effect of ultraviolet sterilizer are mainly divided into two categories: product quality and disinfection water condition. Although ultraviolet disinfection has certain limitations, its advantages such as fast sterilization, low cost and no dead angle are also very obvious, so its application is becoming more and more extensive.
