Know the Difference: "Good" Ozone vs. "Bad" Ozone
Once again, ozone was in the news in July 2011 when the EPA announced it would issue new regulations to reduce the amount of ground level ozone permitted. Aside from the chorus of complaints about the regulatory costs this would impose (the only way to reduce ground level ozone is to emit less exhaust from fossil fuel combustion), the news stories once again promoted the "bad" side of ozone. This brief whitepaper puts ozone in context, showing the beneficial sides of this potent oxidizer when it is controlled for human purposes.

Ozone (O3) in Drinking Water Treatment - 106 years & still going
This article by Jim Eagleton (written when he was working at the EPA) is a classic statement of the performance of ozone as a water disinfectant. It is aimed at drinking water treatment, but applies largely to commercial aquatic applications as well. Well worth a read!

Understanding Ozone Manufactured from Oxygen vs. Dried Air
Until recently, engineers and aquatics life support professionals agreed on using reliable oxygen concentration methods of feed gas preparation for ozone generation. Now, some have argued that the older dried air feed gas method is preferable. This paper provides the scientific and experiential background why the oxygen concentration approach is better for aquariums' and zoos' animals, as well as providing a more efficient, controllable disinfection capability.

Optimizing Mass-Transfer of Ozone Gas into Aqueous Solutions
A critical issue in ozone disinfection is the efficiency of the ozone system in dissolving ozone into the water body or water spray. The superior method for doing this uses negative pressure produced by a vacuum to draw feed gas through the ozonator and then into the water through a venturi injector. This approach has all but eliminated the alternative bubble diffusion method, which is highly inefficient and ineffective in comparison. See a detailed comparison in the full article, which will download as a PDF in separate window .

What’s so great about ozone water purification?
Maybe you’ve heard of ozone for water purification, maybe you haven’t. But guess what? There are some pretty compelling reasons why you should boost your awareness and understanding of one of the most highly effective natural water purification sources to hit the earth since, well, oxygen.

The Nice Side of Ozone
Ozone is much more than the nasty air pollutant that everyone knows about. It is also the naturally occurring protective layer of ozone in the upper atmosphere. And it is the safest, most powerful natural sanitizing agent we have for a wide range of commercial, industrial, and residential applications.

What is the Relationship Between Ozone and Smog?
On very hot summer days in most major US metropolitan areas there are periodical "Smog Alerts" that are usually announced as "Ozone Alerts" by the Media...While these "Smog/Ozone Alerts" are very real ... there is virtually no correlation between ozone levels in polluted air and ozone used as an antimicrobial water sanitizer.
