The presence of oxygen has changed the chemical structure of the iron. Ozone has the same oxidizing effect but oxidizes many more substances at a faster rate. Ozone is one of nature's strongest oxidizers. Because of ozone's air-freshening effect by oxidation of odors, ozone generators are now used to freshen the air in offices and industrial facilities. Many of these generators use a process called corona discharge to produce the ozone.
Corona discharge occurs by producing controlled sparks in the presence of oxygen.
Ozonation is a process of injecting ozone into the air. The ozone reacts with the odor to produce odorless gases. The most common products of a complete oxidation process are water vapor and carbon dioxide. Picket Fence Farms has this system installed in its hog confinements. The results of ozone installed in their facilities have been very impressive.
