What is the use of a medium-pressure UV disinfectant?

　　The medium-pressure UV lamp provides multi-frequency UV output (with an output range of 185–400 nm). Medium-pressure UV sterilizer Disinfection technology is more suitable for high-flow applications. 2. Details on the wavelength range of medium-pressure UV disinfectors: Ultraviolet light with wavelengths between 185 and 400 nm—also known as ultraviolet C—exerts a strong germicidal effect, with optimal efficacy at a wavelength of 253.7 nm. Within this wavelength range, ultraviolet light penetrates the cell membranes of microorganisms, damages their DNA, and renders them incapable of further reproduction, thereby effectively achieving sterilization.

　　Advantages of Medium-Pressure UV Disinfection Systems: Medium-pressure UV disinfection systems can guarantee both effective disinfection and high-quality effluent water. This is a durable and highly effective sterilization technology that prevents bacterial regrowth, ensuring complete disinfection and water safety. Compared with other sterilization methods, UV radiation offers numerous distinct advantages. In particular, unlike chemical disinfectants, UV sterilization does not introduce toxic substances or residual chemicals into the treated water, nor does it alter the liquid’s chemical composition, odor, or pH level.

　　Advantages of Medium-Pressure UV Disinfectors

　　1. Rapid sterilization—The no-dead-angle medium-pressure UV lamp is a high-power medium-pressure lamp capable of emitting multi-wavelength ultraviolet light. It boasts excellent disinfection performance. It can effectively kill various viruses, bacteria, cryptosporidia, and algae within 2-3 seconds, achieving a sterilization rate exceeding 99.9%. In contrast, traditional chlorine disinfection methods are unable to eliminate cryptosporidia.

　　2. Large processing capacity and low cost: The medium-pressure UV disinfection unit features high power, large water treatment capacity, and simple maintenance. Compared with chlorine and ozone disinfection, it has lower operating costs and does not generate secondary pollutants.

　　3. The medium-pressure UV disinfection unit is easy to install and maintain, with a compact size that makes it simple to set up and service. It only needs to be installed directly into the water pipe. Once activated, it can effectively sterilize and disinfect the water flowing through the pipe, achieving a high disinfection efficiency. Overall, the medium-pressure UV disinfection unit offers significant advantages in terms of disinfection effectiveness and is suitable for sterilizing and disinfecting various types of water, including tap water, swimming pools, and aquaculture water.

　　Application scope of medium-pressure UV sterilizers: 1. Water disinfection in the food processing industry, including pure water systems for drinking water, juices, milk, beverages, beer, edible oils, and various canned and chilled products. 2. Disinfection of water used in hospitals and various laboratories, as well as disinfection of high-concentration pathogenic wastewater. 3. Disinfection of domestic water supplies, covering residential areas, office buildings, water treatment plants, hotels, restaurants, and other similar facilities. 4. Disinfection of cooling water used in the production of biochemical pharmaceuticals and cosmetics. 5. Purification and disinfection of water used in aquatic product processing. 6. Disinfection of water used in swimming pools and water recreational facilities. 7. Disinfection of seawater and freshwater aquaculture water (for fish, eels, shrimp, shellfish, etc.). 8. Ultra-pure water used in the electronics industry, among others. 9. Degradation of certain hardly degradable organic substances in industrial wastewater; disinfection of wastewater from large- and medium-sized drinking water treatment plants; purification and disinfection of swimming pool water; decomposition of residual chlorine and its byproducts in water; degradation of chemical contaminants in drinking water.
