What is UV Sterilization system?
Ultraviolet or “UV” is a type of energy found in the electromagnetic spectrum, lying between x-rays and visible light. Although we cannot see UV light or rays, we are exposed to them every time we step out into the sun. In fact, UV light is responsible for causing sunburns.
UV sterilization systems use special lamps that emit UV light of a particular wavelength that have the ability, based on their length, to disrupt the DNA of micro-organisms. These UV light waves are also referred to as the Germicidal Spectrum or Frequency. The frequency used in killing micro-organisms is 254 nanometers (nm). As water passes through a UV water treatment system, living organisms in water are exposed to UV light which attacks the genetic code of the microorganism and rearranges the DNA /RNA, eliminating the microorganism's ability to function and reproduce. If a microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which it has contact. This process of exposing water to UV light is simple but effective, destroying 99.99 percent of harmful microorganisms without adding any chemicals to water.
Comparison between Quartz lamp and boric lamp:
Made by natural quartz with better penetration to UV ray and provide better germicidal result with longer effective usage life but cost much more than boric lamp. Melting point above 1800°C and hardness higher. Be able to be used in water without chemical substances and side effect.
Made by boric. Penetration rate and effective usage life are about 1/2 compare to quartz though cost is much more less than quartz. Melting point below 1400°C and hardness lower. Boric contains chemical substances and could release toxic substances in water which should not be suggested to be used in drinking water e. production line, carbonated beverage production line etc. The design is scientific and reasonable. Its appearance is beautiful. Its operation and maintenance is convenient.
Features & Advantage
● Cost-efficient frame design, stainless steel material. Individually removable modules. Easy to take out for maintenance and replace.
● Advanced Imported amalgam lamps, more than 12000 hours life time.
● Excellent light transmittance & high-purity quartz sleeves.
● Automatic sleeve wiping system. The wiping sequence occurs automatically at preset intervals without operator involvement excellent performance electronic ballast.
● With its high stability, good heat dissipation, constant UV output, power coefficient over 0.99,variable output (50-100% power), step less regulation and programmable preheated start, it prolongs the UV lamps’ life time more than 20%
● Based system control center continuously online monitors and controls UV lamp status, light intensity, light transmittance and temperature, easy for operator to monitor and control the whole system.
