UV STERILIZER for Water & Air Purification, 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 the air and water purification applications include drinking water, ultrapure water, food and beverage industry, medical application, room air sterilization, sewage treatment. More than a 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.

HOW OUV SYSTEM BE BETTER?

     All UV-C system which produces peak output of 254nm UV rays break down and remove health related problem with chloramines which are formed when free chlorine reacts with organics such as sweat, body fats, and urine. But our OUV system, unlike general UV-c system; our OUV are polychromatic and have a broader UVC peak output at 185nm and 254 nm. This broader range of UVC light output can remove all types of Chloramines (mono-, di- and tri- chloramines).

     After just a few days of UV operation, combined with chlorine level typically fall too low as 0.1 ppm or lesser. It will reduce all health related Problems with itchy skin, burning red eyes, chlorine smell and corrosive properties are eliminated. Pool water is transformed to sparkling and clean looking.

     Our OUV system also provides an increased level of disinfection, protecting against most of the chlorine resistant microorganisms such as Cryptosporidium and Giardia, which have a thick outer membrane making them highly resistant to traditional chemical disinfection. By adding ozone to the water to oxidize ammonia and nitrogen compounds. The longer the system operates, the more the ozone can destroy the ammonia and nitrogen.

     Ozone has been used for algae elimination for years with very good results. When compare ozone with some other very strong oxidants; ozone obtains very good results in a short amount of time more than Potassium permanganate & Chlorine & Hydrogen Peroxide. Combined system UV sterilizer and ozone perfectly control the algae formation. For almost all kind of algae, ozone can reduce more than 95%. Ozone systems effectively fight against Algae and maintain superb water quality. Marine hobbyist recognized the advantages of Ozone systems along the past.Without dispute, Ozone is the most effective natural bactericide and viricide of all disinfecting agents available.

  • We use combination of UV rays & Ozone gas to disinfect pool water instead of Chlorine which is much more safer for Skin and Health of swimmer because there is no residual chemicals to be harmful for Human, no carcinogen.
  • There is 2 types of UV rays in our system : 185 nm UV rays and 254 nm UV rays.
  • 185 nm UV rays will remove Total organics content ( reduce TOC ) and also reduce Algae production.
  • 254 nm UY rays will kill bacteria , Viruses , Molds without any chemical added.
  • Ozone gas will be mixed with pool water by Venturi to oxidize all pollutants in water and kill bacteria, Viruses, Molds, Reduce Algae.

TOC Reduction

  • UV rays will have no residual effect in the pool after passing UV reactor but dissolved ozone will remain exist in the pool 15-40 minutes depend on temperature of pool water (cold water will keep longer dissolved ozone) .Therefore in season which temperature is cold (lower than 20 celcius) without sunlight -> No use of Algaecide solution.
  • But in Hot season & direct sunlight exposure , Algae may build up (since dissolved ozone can exist in water only 15-40 minutes). Therefore strongly recommend to mix Copper Sulphate solution at concentration 0.5 gram/1,000 liters of pool water per week to completely prevent Algae production.

THERE ARE 2 MAIN APPLICATIONS OF UV STERILIZER 254nm IN WATER TREATMENT INDUSTRY:

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 a 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 a 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 operates.
  • 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.
  • STANDARD UV STERILIZER: To sterilize water flow rate 8GPM to 120GPM
  • LARGE COMMERCIAL PRODUCT: To sterilize water flow rate 160GPM to 960 GPM
  • MEDICAL – SANITARY UV STERILIZER

    2) OZONE DESTRUCTION:

    Another application of UV in Water Treatment Industry:

         Some water treatment applications, Ozone gas is injected into the water stream to oxidize trace organics or to disinfect the piping and distribution system, but residual ozone is often remained at Point-of-Use P.O.U. In some application, there is no 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.

    Ozone Destruction

    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.
