Negatives of Ozone

Let's take a closer look at the real ozone negatives.

Like every oxidant, ozone has its down-sides. However, it is important we clarify the actual negatives vs. the perceived "negatives" that arise from misuse.

Commonly stated "negatives"

  • material degredation
  • can harm people, pets, plants
  • oxidizes materials

In light of ozone's effectiveness, are the three items really negatives, or do we just need to use it safely like electricity, or gasoline? All oxidizers will have similar "negative" effect if used improperly. Proper implementation is critical to achieving outstanding results in your process.

The real negatives are listed below

Half Life: Ozone is an unstable molecule which quickly changes back to oxygen. The time for half of the ozone in air to decompose (half-life) is 20-60 minutes depending on the temperature and humidity of the ambient air. The half-life in clean water is about the same. Note: the temperature, pH, and water quality will affect half-life.

Storage: Ozone cannot be stored or transported, but must be made on site. This requires feedgas preparation and
ozone generation equipment. it would be ideal if ozone could be contained in a bottle and delivered onsite. We just aren't there yet.

When can a negative be a positive? Since ozone cannot be stored, it is not possible to have a large, potentially dangerous volume of oxidizer such as you can have for chlorine or hypochlorite. Ozone equipment, which is required for all ozone applications, can neither be "punctured" with a fork lift nor "tipped over."
