Six applications of ultraviolet sterilizers in water treatment

2023/03/18

The ultraviolet sterilizer mainly uses ultraviolet rays to irradiate microorganisms, and the ultraviolet sterilizer will transfer and accumulate energy, and the accumulated results will cause the inactivation of microorganisms, so as to achieve the purpose of disinfection. Among them, sewage ultraviolet sterilizers and swimming pool water uv sterilizers are widely used in the water treatment industry. Today, almost all industries apply ultraviolet technology to water treatment systems. Sterilization is the main application of ultraviolet technology in the field of water and wastewater.

The main advantages of ultraviolet sterilizers in water treatment are reflected in the following aspects: 1. Sterilization: ultraviolet sterilizers mainly use ultraviolet light with a wavelength of 254 nanometers. Ultraviolet light of this wavelength, even under a small amount of ultraviolet projection dose, can destroy the life core of a cell - DNA, prevent cell regeneration, lose the ability to regenerate and make bacteria harmless, thereby achieving the effect of sterilization. 2. Reduce the amount of total organic carbon: In many high-tech and laboratory installations, organic matter will hinder the production of high-purity water.

In the use of UV sterilizers, there are many ways to remove organic matter from water. The more common methods include the use of activated carbon and reverse osmosis. UV rays with shorter wavelengths have more energy and are therefore able to break down organic matter. 3. Liquid sugar disinfection: Since sugar is a food that is easily utilized by bacteria, it is easy to promote bacterial reproduction.

Plus, liquid sugar is opaque, so it's hard to sterilize thoroughly. To compensate for the energy loss caused by the viscosity and color of the liquid, many UV emitters need to be packed tightly together to form a so-called "thin-film" reactor. 4. Degradation of residual chlorine: In municipal water treatment and water supply systems, chlorine disinfection is very necessary.

However, in the industrial production process, in order to avoid adverse effects on the product, the removal of residual chlorine in water by ultraviolet sterilizer is often a necessary pretreatment. The basic methods for eliminating residual chlorine are activated carbon bed and chemical treatment. The disadvantage of activated carbon treatment is that it needs to be constantly regenerated, and it often suffers from bacterial growth problems.

5. Surface and air disinfection: The use of ultraviolet sterilizers for air disinfection has a long history as the use of ultraviolet rays for water disinfection. Air disinfection equipment has been used in hospitals, clinics and decontamination rooms for many years. The principle of air disinfection is the same as that of water disinfection.

Typically, UV lamps can be installed in the air duct, in front of the coil, or mounted on a shelf fixed to the wall. When the air passes by, the microorganisms in the air are killed and rendered harmless. 6. Cooling tower disinfection: In order to reduce the cost of biocides and the health hazards of chemical treatment, the ultraviolet system in the ultraviolet sterilizer can be installed in the water circulation system of the cooling tower to play a role in sterilization.

When used in conjunction with filters, UV light can effectively control microbial growth in cooling towers. Although a certain concentration of biocide still needs to be retained in the cooling tower, the application of a UV sterilizer can greatly reduce its usage. Guangdong Boying Environmental Protection Equipment Co., Ltd. is a professional manufacturer of ultraviolet sterilizers that produces and develops various specifications of ultraviolet sterilizers.

Boying UV sterilizer has the advantages of high stability of radiation intensity, sterilizing life of up to 9000 hours, equipped with high transmittance quartz glass tube, and its light transmittance is ≧87%. The unique high-brightness mirror sterilization reaction chamber design of the ultraviolet sterilizer increases the sterilization intensity by 18-27%.
