Ozone for Disinfection, Oxidation
Ozone or O3 provides advanced oxidation and disinfection in applications
ranging from water treatment to odor control. Ozone is the fastest acting
oxidizer and sanitizer available for commercial or industrial use. Because of
this, Ozone has found a home in numerous industries. Ozonated swimming
pools can eliminate or reduce the need for chlorination and it’s attendant
health problems. Most of the commercial applications of Ozone are aimed at
replacing chemical-based oxidizers and sanitizers with an environmentally-
friendly alternative. Besides its powerful oxidizing and sanitizing capabilities,
since Ozone is oxygen-based, it is inherently much healthier than a chemical-
based system. Ozone is the fastest-acting commercially-available sanitizer
and oxidizer on the planet. It is a much faster oxidizer than chlorine, flourine
or or other chemical oxidizers.
Most of the health issues with chemical systems arise from disinfection or
oxidation byproducts. That is, when chemicals react, they often break down
into substances that are very harmful. Chloro-organic by-products are often
much more dangerous than the original substances. In fact, many of these
byproducts contain recognized carcinogens. With Ozone, which is an oxygen-
based sanitizer and oxidizer, the reactive third Oxygen molecule simply
reverts back to the more stable form of Oxygen.
Envron Ozone is dedicated to helping you find the right oxidation or sanitation
solution based on your needs and the recognized ability of Ozone to work
within your particular application or process. Besides full-scale process
systems, Envron can provide prototyping, bench-scale and pilot-scale
systems for unique or novel Ozone applications or processes.
Ozone is one of the most useful, ecologically sensible substances on planet earth. In it’s “raw” form in nature, it is
essential for all life on this planet. Without the Ozone layer, we wouldn’t exist. Ozone is Mother Nature’s supreme
disinfection and cleansing agent. It is a superior oxidizer and sanitizer and works much faster than chlorine. Chlorine
replacement is one of the chief uses of Ozone.
Ozone is an advanced form of Oxygen that is applied in industries including aquaculture, odor control, medical
treatments, disinfection, home remediation, dentistry, manufacturing, swimming pools, laboratories, hospitals,
zoological, municipal water treatment and numerous others. It has been in constant use since it’s discovery over 100
years ago. It can be used to complement or replace chlorine. In applications where no chlorine is a must, Ozone is
the technology of choice.
Applications
Ozone is one of the most studied technologies on the planet. As with any technology, there are situations where
Ozone can accomplish a great deal. And while Ozone systems are for the most part mechanically quite simple, the
science and chemistry behind proper Ozone application is often more challenging. For chlorine replacement or in
situations where chlorine is not acceptable, Ozone can be used effectively.
In any Ozone application, you must understand the basic operating chemistry and reaction kinetics in order to
properly apply the technology. What are some of the glaring examples of the misuse of Ozone? We have seen
situations where a larger Ozone generating system of 60 grams/hr. output was coupled to an inadequate water
contacting system. When measured, the actual Ozone dissolved in the water was equivalent to 4 grams/hr. By not
understanding the correct Ozone concentration to water volume kinetics, the system essentially wasted 56 grams/hr.
of Ozone because it did not have the capacity to dissolve it. Obviously, chlorine replacement in this situation was
hampered.
In what appeared a very straightforward application, the system designers failed to understand the correct Ozone
concentration vs. water volume to effectively utilize the capacity of the Ozone system. The owners of this system
could have easily reported that Ozone "failed" and that somehow basic Ozone chemistry does not work. Chlorine
would have been the fallback position.
Ozone Chemistry
However, Ozone chemistry is well understood. In situations where we have seen a "failure" of Ozone, it is usually the
misapplication of this very useful, environmentally friendly technology that is to blame, rather than whether Ozone
"works" or does not work. In cases where Ozone is seen not to work, it is usually an ignorance of the basic operating
parameters of this technology and/or not understanding the reaction kinetics involved that lead to system failure. In
instances where Ozone is the correct technology and where it has been applied without problems, Ozone offers
numerous advantages over chemical-based technologies. For no Chlorine or limited chlorine situations, Ozone is the
sanitizer of choice.
Envron - Separating Ozone Fact From Fiction
Our goal at Envron is to separate the Ozone fiction from the Ozone facts. Because this technology is one of the most
studied technologies on the planet, it is doubtful you are coming up with a "new" use of Ozone. Chances are,
someone has already applied (and studied) Ozone for what you are attempting to accomplish. If you truly have a
unique application for Ozone, we can assist in establishing a pilot study to see whether this technology can be used
in your situation. In general principles, Ozone can replace most Oxidizers on the market and bring you a total cost
savings. These include oxidants such as chlorine, flouride, Hydrogen Peroxide and others.
What are some of the things you'll need to consider to apply Ozone and gain these advantages? The first is a sound
understanding of Ozone reaction kinetics. Whether this is for Ozone in air or water applications, there are certain
"rules" that cannot be violated without inviting disaster. Keeping an Ozone system running so that it is producing
enough Ozone to do the job is essential as is a properly constructed reaction system. Especially in chlorine
replacement situations. This must take into consideration the operating environment of the system and the mechanics
of the reactor. It is one thing to produce Ozone and, as we have seen from our example above, another thing to utilize
the Ozone effectively and efficiently to accomplish objectives.
Please do not hesitate to contact us with your questions about this technology. We'll be happy to assist you in your
search for the proper application of this extremely useful technology.
