UV water sterilizer for water treatment

UV water sterilizer for water treatment   Application   Range of application    Working Principle   UV water treatment working principle UV disinfection is the international industrialized latest water disinfection technology,which is with thirty years of research and development in the late nineties. Application of UV disinfection is among 225 ~ 275nm, peak wavelength of 254nm ultraviolet spectrum of microbial nucleic acid to destroy the original body (DNA and RNA), thereby preventing protein synthesis and cell division, they ultimately can not replicate the original body of microorganisms, not genetic and eventually death. Ultraviolet disinfection disinfect fresh water, sea water, all kinds of sewage, as well as a variety of high-risk pathogenic body of water. Ultraviolet disinfection sterilization is the world's most efficient, the most widely used technology, the lowest operating costs of high-tech water disinfection products.   Limitation of Use The UV water disinfection system NOT intended for the treatment of water that has an obvious contamination or intentional source, such as raw sewage, nor is the unit intended to convert wastewater to microbiologically safe drinking water.   Water Quality (in) Water quality plays a major role in the transmission of germicidal UV rays. It is recommended that the water does not exceed following maximum concentration levels   Maximum Concentration Levels (Very Important)

Iron	≤0.3ppm(0.3mg/L)
Hardness	≤7gpg(120mg/L)
Turbidity	<5NTU
Manganese	≤0.05ppm(0.05mg/L)
Suspended solids	≤10ppm(10mg/l)
UV Transmittance	≥750‰

  Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added measures to improve water quality to treatable levels. If, for any reason, it is believed the UV transmission is not satisfactory, contact the factory.   UV wavelength (nm) Bacterial cells will die in the UVC(200-280mm) irradiation. 253.7nm spectral line of low pressure mercury lamp has high bactericidal effect and concentrates more than 900‰ output energy of low-pressure mercury UV  lamp   UV Dose The units generate a UV dosage of at least 30,000microwatt-seconds per square centimeter (μW-s/cm2), even at the end-of lamp life(EOL), which is more than sufficient to destroy most waterborne microorganisms, such as bacteria, yeasts, algae etc….  

DOSAGE is the product of intensity & time dosage=intensity*time=micro watt/cm2*time=microwatt-seconds per square centimeter                               (μW-s/cm2)                Note:1000μW-s/cm2=1mj/cm2(milli-joule/cm2)

As a general guideline, the following are some typical UV transmission rates (UVT)

City water supplies	850-980‰
De-ionized or Reverse Osmosis water	950-980‰
Surface waters(lakes, rivers, etc)	700-900‰
Ground water(wells)	900-950‰
Other liquids	10-990‰
