Ozone Generator 101

Often times people stumble across oxygen and ozone healing therapies and become quite excited by what they have discovered, only to find that the learning curve on equipment, methods, protocols and safety concerns is overwhelming. They often give up before giving any oxygen therapy a fair try. This paper will help to demystify the equipment used to produce ozone for air, childcare water and therapeutic purposes.

There are basically two types of ozonators and two accepted methods of ozone production. The two types are air-fed ozonators and oxygen-fed ozonators. The two methods of ozone production are cold corona discharge and ultraviolet. Each type of generator and method of ozone production has its unique features, advantages and drawbacks. The only accepted method of ozone production for medical protocols is oxygen-fed cold corona discharge. The purest ozone is made from what is called dual dielectric medical grade ozone generators because there are no metals in the gas stream of the ozone produced.

Air-fed ozonators These ozonators fall into two categories: air purifiers and water purifiers

Air Purifiers

Air purifiers produce ozone either by corona discharge or by ultraviolet rays in the wavelength of 185 to 220 nanometers.The advantage of cold corona is that they are very efficient, ozonepurity have long life, are fully ozone output adjustable and require very little maintenance. Periodic maintenance depending on environment is required. Simple cleaning of the ozone-producing cell is necessary. The disadvantages of cold corona air purifiers are that they produce NoX (nitrogen compounds) like nitric acid and nitrous oxide in small quantities from room air in proportion to the amount of humidity in the air. The dewpoint temperature of air must be minus 60 C before this is prevented. No matter what a manufacturer claims about their units not producing NoX, this is simply not true if the air has any appreciable humidity. For this reason air-fed ozonators are not acceptable for medical uses. NoX is not much of a concern for the majority of people since the amounts are small and the benefits of the ozone produced far outweigh the NoX impurities. A few people experience bad reactions from the small amounts of NoX produced by air-fed air purifiers. Some air-fed purifiers have an added bonus of an ionizer built into the unit which negatively ionizes particles in the air, minebook making them heavier so they fall to the floor. The health benefits of negative ions are well documented. Ultraviolet air-fed generators have the advantage that they do not produce NoX, even in humid air. They are less efficient than corona discharge, are not output adjustable, and the UV bulbs have to be replaced annually. This is problem because the lamps contain mercury and must be disposed of in an environmentally safe manner. Most States and Provinces have recycling specifically for this purpose. Laws in many places now require manufacturers of such units to provide recycling for the used lamps.Air-fed air ozonators come with a variety of features such as on/off timers, different sizes of and air movement from fans, a wide variety of ozone outputs and features which supposedly make them unique. Air-fed air purifiers are typically measured in mg/hr of ozone output or by the number of square feet the unit is supposed to purify. Beware of false claims! Due Diligence is required to find the perfect air ozonator and reliable manufacturer for your specific needs.

Air-fed water purifiers also can be either corona discharge or ultraviolet. They employ an air pump either internal or external to pump room air through the ozonator. The output gas mixture is then channeled by ozone resistant tubing to a diffuser stone which is placed in the water. This gas mixture, containing ozone, powdervitamin bubbles through the water to purify it. To avoid the presence of NoX in the gas produced by corona discharge air-fed ozone generators, the air can be dried with an air drier which is typically hooked up to the intake of the air pump supplying the air to the ozonator. Nox is not produced by ultraviolet air-fed water ozonators. If the air being supplied to an air-fed corona generator is not dried, nitric acid can build up in the ozone generator. Unless it is allowed to escape, the acid will eventually destroy the ozonator. The quality of the air pump is a concern in a water ozonator, since it is usually the weakest link. The pumps in Chinese ozonators will fail quickly if used to ozonate more viscous liquids like oils for long periods of time. Good quality air-fed water ozonators are inexpensive, effective, and can be used for a number of uses like ozonation of water, nahls oils, soaking vegetables and meats in ozonated water, ozonating bathwater and for short term use as an air purifier. Air-fed water ozonators vary widely in quality, design, price, warranty, output of ozone, features and durability. Air-fed water ozonators are typically measured in mg/hr of ozone output. This is a measure of the amount of the molecular weight of the ozone produced in one hour. Beware of false claims here as well. Due Diligence is also required when choosing an ozonator for these purposes. One main feature of air-fed water ozonators is portability. They are relatively small and portable.
