Which is better; UV (ultraviolet) Ozone Generation or Corona Discharge?

WE SELL both CORONA DISCHARGE and UV OZONE GENERATORS, so this is not biased information!

Do not confuse UV Sterilizers with UV Ozone Generators...UV sterilizers do not produce ozone.  UV Ozone Generators produce large amounts of Ozone.

UV ozone generators are the best choice for all air and surface sterilization applications include MOLD treatment, Fire, Smoke, Flood, ODOR, Protein Decomposition, Germ, Virus Remediation and many other ozone uses

The ozone output from all ambient air Corona Discharge Ozone Generators is significantly diminished by humidity and deposits (from the corona process):

An analogy or example of a corona discharge:

Electricity that jumps across any medium or set of electrodes is considered a corona discharge.  Static electricity is a corona discharge. Lightning is a corona discharge. 

Most know that when the environment is very dry (as with freezing temperatures in the winter) static electricity discharge is often experienced.  The same effect is realized for ozone generators using the corona discharge technology.  The corona process of an ozone generator is similar to an abundance of controlled static electricity in a box.  This process produces ozone which is useful for shock treatments and air purification.

Why are UV ozone generators a better choice than corona discharge ozone generators?

(For all air or surface sterilization Shock treatment applications such as MOLD, Smoke, Fire odors, musty smells, flood odor, protein decomposition odor, germ and virus remediation, etc.)


The Biggest difference between corona discharge and UV ozone generation methods is that UV ozone generators have stable ozone output levels throughout humidity ranges, while the output of corona discharge ozone generators is significantly reduced by just moderate humidity levels such as 40–70% (ozone output is reduced by approx. 40-70% with 40-70% humidity). In addition, with UV ozone generators, the cleaning requirement is almost eliminated compared to corona discharge ozone generators. Also, the ozone produced from a UV ozone generator is cleaner (no nitric acids) and smells better than ozone produced from corona discharge machines, and is just as powerful and often more powerful as ozone produced by corona discharge ozone generators.
UV ozone generators include UV PRO 550, UV PRO 550AT, UV PRO 1100AT, UV PRO 2800, UV PRO 4000, and UV PRO 6800

I know this is redundant, but there are a couple unethical sellers that are pushing false information to sell their product any way they can;

Regardless of claims, all corona discharge ambient air ozone generators will produce their maximum ozone in a dry environment, such as below 10% humidity.  Some users, such as those in Arizona and other dry or desert areas will experience the maximum output from their corona discharge ozone generators in these areas because of the ultra-low humidity conditions, which is sometimes in the single digits. 
 

The reason humidity greatly reduces ozone output of corona discharge ozone generators is because a corona discharge ozone generator is basically millions of static electricity lightning bolts on a thin film, and as you know humidity eliminates static electricity, the corona process is significantly reduced. The reduction is typically linear with the humidity level, so if there is 60% humidity, there is at least 60% less corona activity, or 60% less ozone output.

When a seller states their Corona Discharge ozone generators are rated for their maximum ozone output in high humidity....well just think about that and you know it does not make sense.  Any corona ozone generator will produce its maximum ozone in an environment with ultra low or no humidity.

  So, In review:

UV ozone generators are superior for all ozone air treatment and ozone shock treatment uses because of:

  • stable, consistent ozone output throughout all humidity ranges; ozone production is not affected or diminished by humidity
  • Zero Nitrogen Oxides
  • significantly reduced cleaning/ maintenance, also easier to clean
  • cleaner ozone production with no by products
  • UV ozone Generators are the most reliable commercial ozone generators, even in adverse conditions and temperatures.
  • Our UV ozone machines also produce Hydroxyl Radicals as well as ozone.  Hydroxyl Radicals are aggressive at killing germs that go through the machine, though they cannot travel throughout a building as their life expectancy is only a few seconds.  It is the Ozone our UV Ozone Generators produce that travels throughout the building killing germs during shock treatments.

The most Popular commercial ozone generator used by leading fire smoke flood mold odor and death scene remediation companies is the UV PRO 6800 followed by the  the UV PRO 4000, and UV PRO 2800.

See Also: Ambient Air Ozone Generators Compared to Oxygen Fed or UV Ozone Generators  For all air or surface sterilization Shock treatment applications such as MOLD, Smoke, Fire odors, musty smells, flood odor, protein decomposition odor, germ and virus remediation, etc. UV ozone Generators are the best choice.  Read further below to understand why.

Industrial applications such as wastewater treatment, water bottling, and laboratory scientific research often require significant concentrations of ozone greater than what ambient air corona discharge or UV ozone generators designed to be used for shock treatments produce.  So for water treatment applications the Corona Discharge technology will be used only with Heated Desiccant air driers, or pure oxygen for feed gas.  Industrial high powered systems are available on our Ultra Pure Water Treatment Products page.

For Shock treatment applications such as MOLD, Smoke, Fire odors, musty smells, flood odor, protein decomposition odor, germ and virus remediation, etc, the UV ozone Generator line will be the best choice.

o3ozone offers both UV (ultraviolet), and Corona discharge Ozone GeneratorsWith ambient air systems, UV ozone generation is superior because of stable high outputs and reduced cleaning/ maintenance.  UV Ozone Generators:

UV Ozone Generators:
UV PRO 550 Ozone Generator
UV PRO 1100 Ozone Generator
UV PRO 2800 Ozone Generator
UV PRO 4000 Ozone Generator
UV PRO 6800 Ozone Generator

The new VU ultraviolet ozone Generators (UV PRO 2800, UV PRO 4000) shown near the bottom of this page are more powerful that the PRO 5,000, PRO 9,000 under normal humidity levels (40-50%).  At higher humidity(50%+), the UV PRO 2800, UV PRO 4000 ultraviolet ozone generators will outperform the PRO 5,000, PRO 9,000 ambient air corona discharge ozone generators.

UV Ultraviolet ozone producing systems produce more than adequate concentrations of ozone needed for these shock treatments, contrary to some advertisements.  Some advertisements refer to UV ultraviolet Sterilizer bulbs (see below)  claiming that all UV ozone generators are simply UV sterilizers (which do not produce ozone).  Ozone concentration is measured in Parts Per Million (PPM).  It only takes 3-4 PPM to kill off all germs, including MOLD, Bacteria, and Viruses.

Shock treatment Applications that are in humid locations, can be performed with the UV PRO 550 Ultraviolet Ozone Generator in 1,000 sq. ft. sections at a time.  For a comparison, the PRO 3400 V1 (1,000mghr) corona discharge ozone generator will give almost equal results in 50% humidity to the UV PRO 550 (the UV PRO 550 is more powerful than the PRO 3400 V1 at 50% humidity).  Unless you intend to use the ozone generator in an occupied area where adjustability will be required, the UV PRO 550 Ultraviolet Ozone Generator will be more than adequate for shock treating areas up to about 1,000 square feet(+ or - 10 %).

Sizing a Generator.


Some information below may be a bit redundant, but if the differences between UV ozone generators and corona discharge ozone generators is not clear, it may be helpful:

If you need an ozone generator with adjustable ozone output, two new models, the UV PRO 550AT or UV PRO 1100AT are ideal.  The "AT" stands for Adjustable with 48 hour Timer.  These models produce the cleanest and sweetest ozone ever possible - adjustable down to very low levels or high levels for shock treatments and are much more dependable than corona models on the market!  Please call 330-497-6900 for information or to purchase.

 

Advantages of Corona Discharge ozone generation:

  • Creates higher quantities of ozone more efficiently (only applies to ozone systems designed to be used with either heated desiccant air driers or oxygen feed gas)

  • Corona cell life exceeds the life expectancy of any UV bulb (only applies to ozone systems designed to be used with either heated desiccant air driers or oxygen feed gas)

  • Small construction allowing generator to be installed in virtually any area

  • Highest ozone concentration possible of any type of ozone generation (only applies to ozone systems designed to be used with either heated desiccant air driers or oxygen feed gas)

  • Industrial Systems can use preparations of oxygen, doubling the output of ozone per volume vs. dry air or ambient air

  • More cost-effective than UV-ozone generation for large scale high concentration installations. (only applies to ozone systems designed to be used with either heated desiccant air driers or oxygen feed gas)

  • less electrical energy is required to produce a the same quantity of ozone

  • Higher gas phase concentrations means the handling of lower gas volumes (again, this applies to ozone systems designed to be used with either heated desiccant air driers or oxygen feed gas)


 

Advantages of Ultraviolet (UV) ozone generation:

  • significantly reduced cleaning/ maintenance and easier to clean
  • Zero Nitrogen Oxides (000.000, while corona discharge ambient air systems are always 0.08%+; this is a lot!)
  • UV (ultraviolet) ozone production is not affected or diminished by humidity
  • stable and consistent ozone output throughout all humidity ranges
  • cleaner ozone production with no by products
    UV ozone Generators are the most reliable commercial ozone generators, even in adverse conditions and temperatures.
     
  • Our UV ozone machines also produce Hydroxyl Radicals as well as ozone.  Hydroxyl Radicals are aggressive at killing germs that go through the machine, though they cannot travel throughout a building as their life expectancy is only a few seconds.  It is the Ozone our UV Ozone Generators produce that travels throughout the building killing germs during shock treatments.


Disadvantages of UV ozone generation:
(disadvantages do not affect the type of systems treating air or mold as the differences in concentration are realized when using oxygen)

  • Maximum ozone production rate is two grams/hr per UV bulb - depending on size while CD systems can obtain much higher concentrations (only when used with either heated desiccant air driers or oxygen feed gas)

  • Highest ozone concentration that can be produced by 185-nm UV lamp is 0.2 percent by weight, approximately 10% of the average concentration available by corona discharge (only applies to ozone systems designed to be used with either heated desiccant air driers or oxygen feed gas). (higher concentrations are needed for proper ozone water treatment and other industrial applications)

    Note that 0.2% of ozone is a significant level; this is why ozone concentration is measured in Parts Per Million (PPM).  It only takes 3-4 PPM to kill off all germs, including MOLD, Bacteria, and Viruses.

  • more electrical energy is required to produce a the same quantity of ozone

  • Lower gas phase concentrations of ozone means the handling of much higher gas volumes

  • UV lamps solarize over time, requiring periodic replacement (after 9-16 months of continuous use)


Disadvantages of Corona Discharge ozone generation:

  • Ambient air corona discharge systems require periodic cleaning unless pure oxygen or an electronic heated desiccant air drier is used.

  • Production of nitrogen oxides when used without pure oxygen feed gas or an electronic heated desiccant air drier, regardless of claims

  • Humidity affects ALL ambient air fed corona discharge systems - just as static electricity is reduced or eliminated by humidity...Regardless of claims.

It is recommended to use UV ozone generators over corona discharge ozone generators for all air applications including MOLD treatment, Fire, Smoke, Flood, Water, ODOR, and Germ, Virus Remediation.  UV ozone generators will last longer and require minimal cleaning and maintenance while maintaining consistent ozone output.  The ozone output from all ambient air Corona Discharge Ozone Generators is significantly diminished by humidity and deposits (from the corona process).



UV Ozone Bulbs vs. UV Sterilizer Bulbs

Note that UV ozone generators are not simply UV sterilizers, but high output UV ozone generators.

There is a big difference in the two types of UV bulbs used - often they are confused. 

The bulbs included in our
UV ozone generators produce high levels of ozone for Shock treatments.  With these ozone producing bulbs, ozone air purification of a room can usually be obtained in a just few minutes of use.  Longer treatment times will result in high levels of ozone for shock treatment use - these high levels are for germ and mold killing treatments and should be done while no one is in the room.

o3ozone will soon be offering UV sterilizer bulbs that are interchangeable with the UV ozone producing bulbs of our UV Ultraviolet Ozone Generators for those wanting small room occupied air purification without high output ozone production.

UV ozone generation is superior because of stable high outputs and reduced cleaning/ maintenance.  see the UV Ozone Generators: UV PRO 550, UV PRO 2800, and UV PRO 4000.
