Examples of uses of this molecule in Industry and Healthcare
Ozone allows to disinfect water used for fish farming, food manufacturing and sanitation.Food
Ozonated water is used to sanitize surfaces and disinfect products. Ozone is also used for swimming pools, spa, laundry, odor control, etc.
Ozone is used to decrease Chemical Oxygen Demand (COD) of waste water. Ozone permits to obtain good decolorization of waste water effluents.Waste & Water management
Ozone allows environment-friendly paper pulp bleaching. Ozone is used to reduce the residual fluorescence coming from the optical whiteners of the waste papers. It is also used to treat specific effluents.
Ozone is used in chemical synthesis and for treatment of wastewater.Pharma & Biotech
Ozone is used to oxidize materials such as silicon to silicon dioxide. It is also used to ash photoresists. Ozone allows to achieve Chemical Vapor Deposition (CVD) of oxides.Electronic components
Information to safely use this molecule
Recommendations : Air Liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system. Although the information has been compiled from what Air Liquide believes are reliable sources (International Standards: Compatibility of cylinder and valve materials with gas content; Part 1- Metallic materials: ISO11114-1 (March 2012), Part 2 - Non-metallic materials: ISO11114-2 (April 2013), it must be used with extreme caution and engineering judgement. No raw data such as these can cover all conditions of concentration, temperature, humidity, impurities and aeration. It is therefore recommended that this table is only used to identify possible materials for applications at high pressure and ambient temperature. Extensive investigation and testing under the specific conditions of use need to be carried out to validate a material selection for a given application.

Ozone was discovered in 1789 by Martin van Marum, however Christian Friedrich Schönbein is considered as the father of ozone. Its name comes from the Greek word "ozein", meaning "smell". Ozone is formed by the combination of three oxygen atoms. Ozone is an unstable gas with a strong and irritating odor (which explains its name), corrosive, very toxic and a strong oxidant. Ozone is generally produced by generating high-power electrical discharges in air or in oxygen. Naturally found in the upper layers of the atmosphere, where it is formed by a photo-chemical reaction, ozone serves as a shield which protects our planet from the sun's ultraviolet radiation.
