This invention primarily concerns a method and process of finding and using the most efficient operating conditions that can be employed during the production of Ozone using conventional and unconventional Ozone generators and air or relatively pure Oxygen as the main precursor source of the Ozone.

Ozone is a useful allotropic form of Oxygen that is a particularly effective sterilizing and disinfecting agent.  In addition, there are many well known food related and medical sterilization applications, as well as water purification applications, that involve the use of Ozone as a primary aid in related sterilization or purification processes.  In these sterilization/purification processes Ozone is typically used in combination with air or in relatively pure Oxygen because it can be generated quite easily within these gases and it often can be used in these gas streams without the need for additional steps to separate or purify the Ozone before its final use.  However, in many applications, not all of the generated Ozone is consumed or converted back into Oxygen during a particular Ozone treatment process.  And, it is not good practice to vent large quantities of spent gas streams, containing relatively high concentrations of Ozone, into the ambient atmosphere since Ozone (in relatively low concentrations) is harmful to all biological organisms.

So, there is a need to generate only enough Ozone, in concentrations sufficient to accomplish the process at hand.  There is also a need to producing Ozone in concentrations that are higher than that needed to accomplish some type of Ozonation process is also wasteful in terms of the energy that must be consumed to produce higher than necessary concentrations of Ozone.  Energy consideration is an important factor in operating electrical Ozone generating systems when air or recycled Oxygen is used as the Ozone precursor gas source since air use has no cost associated with it and recycled (plus “make-up”) Oxygen can be completely converted entirely into Ozone.  So, in these cases, the only cost that can be easily minimized is the cost associated with the electricity (or power) needed to produce the Ozone.  However, to the best of this writer’s knowledge, no Ozone generation system manufacturers have described or even contemplated how to get the best Ozone generation performance from their existing commercial equipment.

They typically provide charts or graphs (e.g., see Figures 1 and 2, generated using an Ozonia/Ozat, Type CFS-7 Ozone Generator) that show how Ozone concentrations vary with gas (air or Oxygen) flow rate and power input to their particular hardware models.  And, it is left to the end user to pick some particular gas flow rate and operating power level, based (directly or indirectly) on these charts, to produce a particular Ozone concentration (usually in weight % or in volume %) in the gas stream exiting the...
