Ozonization

 

the use of ozone in the purification and deodorization of air and water. Air is ozonized by installing ozonators where perishable goods are processed and stored, for example, in canneries and meat-processing plants; sometimes ozonators are used in crowded premises. Water is sterilized by saturation with ozonized air in special reservoirs, or sterilizers; a major advantage in using this method is the elimination of any residue that may be found in the water. The term “ozonization” is occasionally employed to refer to the use of ozone as a chemical oxidizing agent.

(2012), the decolorization process via ozonization is rapid in both alkaline and acid conditions due to the electrophilic nature of the direct (attack by [O.sub.3] molecules) and indirect (attack via HO* radicals) ozonation process, which considerably facilitates the reaction with the azogroups (chromophore centers).
