Uses of ozone in various fields
Industrially, ozone is used to:
• disinfect laundry in hospitals, food factories, care homes, etc.;
• disinfect water in place of chlorine;
• deodorize air and objects, e.g. after a fire; this process is extensively used in fabric restoration;
• kill bacteria on food or on contact surfaces;
• ozone swimming pools and for spas sanitation;
• scrub yeast and mold spores from the air in food processing plants;
• wash fresh fruits and vegetables to kill yeast, mold and bacteria;
• chemically attack contaminants in water (iron,arsenic, hydrogen sulfide, nitrites, and complex organics lumped together as “colour”);
• aid flocculation (agglomeration of molecules, which aids in filtration, where the iron and arsenic are removed);
• manufacture chemical compounds via chemicalsynthesis ;
• clean and bleach fabrics (the former use is utilized in fabric restoration) (the latter use is patented);
• assist in processing plastics to allow adhesion of inks;
• age rubber samples to determine the useful life of a batch of rubber;
• clean hospital operating rooms where air and surfaces needs to be sterile;
• eradicate water borne parasites such as Giardia and Cryptosporidium in surface water treatment plants.
• Ozone is a reagent in many organic reactions in the laboratory and in industry.
• Ozonolysis is the cleavage of an alkene to carbonyl compounds.
• Ozone will oxidize metals (except gold, platinum, and iridium) to metals oxides in their highest oxidation state
2 Cu2+ + 2 H+ + O32 Cu3+ + H2O + O2
• Ozone converts oxides to peroxides:
SO2 + O3 SO3 + O2
• It also oxidizes oxides to oxides of higher oxidation number:
NO + O3 NO2 + O2
• Most important use in medical field as ozone therapy..
