Ultraviolet disinfection is an advanced sterilization technology based on physical principles. It destroys the DNA chains of microorganisms by emitting ultraviolet light waves of a specific wavelength, achieving an instant, efficient, and chemical-free sterilization effect.
一．Core advantages and application value of medium pressure UV system
1.Due to its technical characteristics, medium-pressure UV systems demonstrate irreplaceable value in the following scenarios:
(1).Ensuring water quality safety (swimming pools, water supply)
(2).Highly effective sterilization
(3).Chloramine elimination and improved air quality
(4).Carcinogen reduction
2.Improve operational economy and reliability
(1).Energy saving and long life: using high-quality lamps imported from Europe and the United States, with a service life of up to 5000-8000 hours.
(2).Reduce operating costs: Reduce or even replace the dosage of chemical agents (such as chlorine), saving agent costs and related storage and safety handling costs.
(3).Small temperature limit: wide working environment temperature range (0-60°C), more adaptable
(4).No chemical residue, pure physical disinfection, does not change the chemical properties of water, and does not produce harmful by-products.
二．Technical comparison of medium-pressure and low-pressure UV
(1).Wavelength and Sterilization Efficiency: Low-pressure UV systems typically output a single wavelength, with a peak at 254 nm and a transmittance of approximately 75%. Medium-pressure UV systems, on the other hand, have a broad spectrum (200-400 nm) and a transmittance of 95%.
(2).Applicable Scenarios: The low-pressure system is suitable for low-flow and low-volume scenarios, while the medium-pressure system, with its high power output and multi-wavelength characteristics, can handle high-flow and high-volume challenges, such as municipal water supply systems, sewage treatment plants, and large swimming pool circulation disinfection.
Medium-pressure UV technology, with its multi-wavelength, high penetration, and high power characteristics, achieves a perfect balance between sterilization efficiency, operational economy, and environmental friendliness.
