UV germicidal lamps are widely used in raw water treatment, pure water treatment, and pharmaceutical enterprises. The following is a detailed explanation of their application methods:

Application in raw water treatment

In raw water treatment, UV germicidal lamps are mainly used for disinfection and sterilization. Raw water usually contains various microorganisms, such as bacteria, viruses, etc. If these microorganisms are not treated, they may have adverse effects on the subsequent water treatment process and water quality. UV germicidal lamps use ultraviolet radiation to destroy the DNA or RNA structure of microorganisms, thereby preventing their reproduction and replication, achieving the purpose of disinfection and sterilization.

The specific application methods of UV germicidal lamps in raw water treatment include:

· Overflow sterilization: The water flows through a sleeve equipped with UV lamps, and the ultraviolet radiation generated by the lamps disinfects and sterilizes the water. This method is suitable for continuous flow of raw water treatment.

· Immersion sterilization: The UV lamp is directly placed in water and uses ultraviolet radiation to disinfect and sterilize the surrounding water. This method is suitable for static or slow-moving water bodies.

Application in Pure Water Treatment

In pure water treatment, UV germicidal lamps also play an important role. Pure water treatment usually requires higher water quality standards, so the application of UV germicidal lamps is also more stringent.

The specific application methods of UV germicidal lamps in pure water treatment include:

· Used in conjunction with filtering equipment:In the process of pure water treatment, UV germicidal lamps are usually used in combination with precision filters, reverse osmosis membranes, and other filtration equipment to remove impurities such as small particles, organic matter,

· As the ultimate disinfection method:In the final stage of the pure water treatment process, UV germicidal lamps can be used as the ultimate disinfection method to ensure that the water quality meets sterile standards.

Application in pharmaceutical companies

The application of UV germicidal lamps is crucial in pharmaceutical companies. Pharmaceutical companies have extremely high requirements for water quality, as the quality of water directly affects the quality and safety of drugs.

The specific application methods of UV germicidal lamps in pharmaceutical enterprises include:

· Production water treatment: The production water used by pharmaceutical companies usually needs to undergo strict disinfection and sterilization treatment to ensure that the water quality meets production requirements. UV germicidal lamps can effectively remove microorganisms from water, ensuring the sterile state of production water.

· Surface disinfection of equipment: In addition to treating water quality, UV germicidal lamps can also be used for surface disinfection of pharmaceutical equipment. By regularly irradiating the surface of the equipment with ultraviolet radiation, it is possible to effectively kill microorganisms attached to the surface of the equipment and prevent cross contamination.

Matters Needing Attention

When using UV germicidal lamps, the following points should be noted:

· Choose the appropriate ultraviolet wavelength:The killing effect of ultraviolet rays with different wavelengths on microorganisms varies. Pharmaceutical companies should choose ultraviolet wavelengths that can damage the structure of microbial DNA or RNA, such as 254nm ultraviolet.

· Ensure sufficient irradiation time: The effectiveness of ultraviolet sterilization is closely related to the irradiation time. Therefore, when using UV germicidal lamps, it is necessary to ensure that the water flow or equipment surface is exposed to the UV lamp for a sufficient amount of time to achieve good sterilization effect.

· Regular maintenance and replacement of lamp tubes: UV lamp tubes will gradually decay during use, affecting the sterilization effect. Therefore, pharmaceutical companies need to regularly maintain and replace UV lamps to ensure their long-term stable operation.

In summary, UV germicidal lamps have broad application prospects and important application value in raw water treatment, pure water treatment, and pharmaceutical enterprises. By reasonable application and maintenance, water quality standards can be effectively improved to ensure the quality and safety of drugs.
