Ozone production in high concentration and amount is obtained by transferring an “oxygen rich gas” through a strong electrical field. Some oxygen molecules break up due to the extensive energy and the oxygen atoms formed combine with the other oxygen molecules to form the ozone molecule made up of 3 oxygen atoms. As ozone is not a stable gas, it cannot be stored and cannot be subjected to long term transportation. It has to be produced where it is going to be used. For this purpose, ozone production systems (ozone generators) are used. The “oxygen rich gases” used in the production of ozone contain dry air and oxygen. Before air is fed to the ozone generator, it has to be filtered and completely dried. Oxygen is obtained from oxygen tubes in small systems and from oxygen generators in large capacity systems. Ozone is a colourless gas with a sharp odour and it has a very strong oxidising property. After being produced, applying ozone that matches the water or the fluid to be treated is very important. A proper ozone/fluid contact is provided in an appropriate contact field. HOW IS OZONE PRODUCED? Ozone production in high concentration and amount is obtained by transferring an “oxygen rich gas” through a strong electrical field. ("Corona Discharge method"). Some oxygen molecules break up due to the extensive energy and the oxygen atoms formed combine with the other oxygen molecules to form the ozone molecule made up of 3 oxygen atoms. As ozone is not a stable gas, it cannot be stored and cannot be subjected to long term transportation. It has to be produced where it is going to be used. For this purpose, ozone production systems (ozone generators) are used. In the ozone production process explained, above heat is released and the generator gets warm. Therefore, ozone generators have to be cooled continuously with proper cooling water. (low capacity ozone generators may contain air cooling ) Packaged Type Ozonization System Application areas: As ozone is a gas with very high oxidation capacity, it can be used for disinfection and removal of organic/inorganic material. It disappears after being transformed to oxygen without any residue and the formation of any harmful by-product is minimum.
- Pre-ozonization in drinkable water treatment plants (instead of pre-chlorination that forms carcinogenic by-products),
- Ozonization of filled water or flushing water in drinking water bottling plants,
- Organic material removal (KOI oxidation in waste water),
- Oxidation of iron/manganese (removal from water by ozonization + filtration ),
- Oxidation of Nitrite to Nitrate,
- Oxidation of toxic material such as Cyanide, Phenol, Nitrousoxides, Pesticides, Chlorinated Hydrocarbons,
- Colour removal in waste water (Especially textile waste waters),
- Optimisation of biological treatment of waste water. (raising the BOI / KOI ratio),
- Odour removal (Oxidation of odorous organics in the air)
- Use of ozone dosage instead of biocide at cooling towers
- Use of ozonized water rather than CIP chemicals in the cleaning of production lines of the food and beverage industry etc.
- Ozonization in the circulation water of swimming pools (Ozonization + Low dosage of chlorine), · Use of ozonisation in fish production hatcheries. (Especially closed circuit systems),
- Use of ozone rather than chlorine/chlorine dioxide for bleaching in chemical industry Ozonization of surrounding air to extend life of vegetables and fruits in cold rooms.
