UV STERILIZER FOR WATER AND AIR PURIFICATION
GERMICIDAL ; OZONE DESTRUCTION
UV ACTION: Ultraviolet radiation wavelength 254 nanometer (nm) is extremely effective in killing microorganisms such as airborne and waterborne bacteria, viruses, yeasts and molds. Germicidal lamps are used extensively in air and water purification applications include drinking water, ultrapure water, food and beverage industry, medical application, room air sterilization, sewage treatment. More than germicidal property of 254 nm UV rays, it also able to apply for ozone destruction to reduce dissolved ozone gas in the water or ozone gas distributed in the room air.
 
THERE ARE 2 MAIN APPLICATIONS OF UV STERILIZER 254nm IN WATER TREATMENT INDUSTRY:
  1. Germicidal application to kill bacteria, viruses, fungus which UV dosage 30mJ/cm2 is worldwide accepted for optimum dose to disinfect or sterilize the water.
  2. UV rays 254 nm also effectively and quickly dissociate ozone gas into oxygen which commonly call as "OZONE DESTRUCTION".
 
 
1) UV STERILIZER: To sterilize water at optimum UV dosage 30-90 mJ/cm2. Advantages of our UV STERILIZER over conventional UV:
  • 304 Stainless steel UV reactor chamber.
  • Internal polishing as mirror for maximum reflection --> maximum UV dosage 30-90 mJ/cm2 @specified water flow rate.
  • High quality quartz sleeve for highest UV transmission.
  • Special designed - Combination of Quartz sleeve & UV lamp holder in single piece for the most convenient to replace UV lamp or cleaning external surface of quartz sleeves with the most convenient way.
  • High output UV lamp to generate 254 nm UV rays 9,000-13,000 hours lifetime.
  • Electronic ballast 25,000 hours lifetime.
  • Transparent plastic Lamp holder cap to show blue light while UV lamp still operate.
  • Advance design to prevent water by-pass flow inside S.S reactor chamber (without sufficient contact time with UV lamp ).
  • Alarm by light & sound when UV lamp cut-off.
 
2) OZONE DESTRUCTION: Another application of UV in Water Treatment Industry:

Some water treatment applications, Ozone gas is injected into water stream to oxidize trace organics or to disinfect the piping and distribution system, but residual ozone is often remain at Point-of-Use P.O.U. In some application there are not allowance for dissolved ozone at Point-of-Use. The most efficient method to remove residual ozone without chemical add by using UV 254 nm as Post treatment.

UV energy at 254 nm wave length able to catalyze dissolved ozone gas back into oxygen gas. Please click at each section for more details.
