  • Applications

    Ozone (CAS 10028-15-6) is a strong oxidant used across industrial and environmental applications, including disinfection and oxidation in process and drinking water; pulp and paper bleaching and textile processing; odor control and air purification in exhaust streams and facility environments; sanitation and sanitization of food processing equipment and wash water; polymer modification and ozonolysis for surface functionalization or cleavage of carbon-carbon double bonds; surface cleaning and preparation for electronics manufacturing; and treatment of industrial air pollutants by oxidizing volatile organic compounds.
