<\/span><\/p>\n

In the water treatment disinfection system, ultraviolet disinfection has always occupied an important position, low-pressure, medium-pressure ultraviolet sterilizer is commonly used ultraviolet disinfection equipment.<\/span><\/p>\n

 
<\/span><\/p>\n

Low-pressure UV technology: the pressure of the inert gas inside the lamp is approximately0.013MPa<\/span>The lamps are in a negative pressure state. The UV light emitted by the lamp is185nm<\/span>respond in singing254nm<\/span>Monochromatic light spectrum. Conventional low voltage technology with a single lamp power of14-320W<\/span>The low-pressure high-intensity lamp technology is based on the traditional low-pressure UV technology, and the power of a single lamp is much higher in the270<\/span>~800W<\/span>Between them, the UV intensity is much stronger.<\/span><\/p>\n


<\/p>\n

<\/span><\/p>\n

Low-pressure UV can meet the general treatment capacity of water treatment requirements, and is suitable for frequent opening and closing operation requirements of the system. Low-pressure UV lamps have high conversion efficiency, up to 40% power into sterilization energy, low cost, so widely used in pool water, aquaculture water and other disinfection systems.<\/span><\/p>\n

 <\/span>
<\/p>\n

<\/p>\n

 Low-pressure ultraviolet<\/span><\/span><\/p>\n

 <\/span>
<\/p>\n

Medium Pressure UV Technology: The pressure of the inert gas inside the lamp is equal to the atmospheric pressure, which can emit a wider range of multi-wavelength UV rays in the wavelength range of 230-370nm, containing the wavelengths of 245nm, 260nm, 297nm, and 340nm required for the reduction of chloramine.<\/span><\/p>\n


<\/p>\n

<\/span><\/p>\n

Therefore, medium pressure UV is more advantageous for pool water disinfection and chloramine elimination applications in swimming pools.<\/span><\/p>\n

 <\/span><\/p>\n

The output of multi-spectrum UV light can decompose urea and degrade chloramine in the water body, and at the same time effectively enhance the water body penetration rate. Medium-pressure UV work is basically not affected by temperature, and can work normally in the range of 0~80\u2103 water temperature conditions.<\/span><\/p>\n


<\/p>\n

Advantageous Comparison:<\/span><\/strong><\/p>\n

 <\/span><\/p>\n

Low-pressure ultraviolet <\/span><\/strong><\/p>\n

Air pressure inside the lamp 0.013MPa <\/span><\/p>\n

Monochromatic UV spectral output<\/span><\/p>\n

Destroys only the DNA of the microorganism <\/span><\/p>\n

Single lamp power 14-320W<\/span><\/p>\n


<\/span><\/p>\n

 Medium Pressure Ultraviolet<\/strong><\/p>\n

<\/strong><\/p>\n

Air pressure inside the lamp is equal to atmospheric pressure<\/span><\/p>\n

Multi-band spectral output<\/span><\/p>\n

Total disruption of microbial structure<\/span><\/p>\n

Single lamp power400W-10KW<\/span><\/span><\/p>\n

Removes chloramine and other chemical residual chlorine.<\/span><\/p>\n

Medium voltage is less affected by ambient temperature<\/span><\/p>\n

Increased water penetration<\/span><\/p>\n

<\/p>\n

  Medium Pressure Ultraviolet<\/span><\/p>\n

 <\/span><\/p>\n

Low-pressure ultraviolet light, because of its single-spectrum output, only has the function of sterilization and disinfection and algae inhibition in swimming pool water treatment applications. Medium-pressure UV is more efficient and thorough in sanitizing and disinfecting, removing urea and chloramines, and protecting swimmers' eyes and skin from pool water irritation; in addition, medium-pressure UV is effective in improving water penetration, making the pool water look clearer.<\/span><\/p>\n
