Ozone is a powerful oxidant, stronger than chlorine. It is used to disinfect, deodorize, decolorize and decompose organic matter in water. Toshiba's TGOGS™ ozone generator ensures safety, reliability and durability with high efficiency and low power consumption.
Why Ozone?
Effects of Ozone
Highlights
1Ozone is a powerful oxidant, stronger than chlorine.
Ozone is used to disinfect, deodorize, decolorize and decompose organic substances in water. It is also used to prevent formation of THMs(*1) in water.
2Ozone molecules are unstable in water, decaying to ordinary diatomic oxygen molecules.
The ozone system has a low impact on the environment.
3Only feed gas and electric power are required for ozone generators.
Ozone is generated internally without transportation or storage.
- (*1) THMs: Trihalomethanes
Ozone Generator
Principles of Ozone Generation
A large amount of ozone is generated efficiently by silent discharge.
The silent discharge continually occurs without spark when a high AC voltage is applied between the two electrodes placed parallel to each other through dielectric material.
When dry air or oxygen flows between the electrodes, oxygen atoms (O) are ionized, and ozone (O3) is formed in recombination of ionized oxygen atoms (O) and unionized oxygen molecules (O2).

Wide Range of Applications
For Municipal Field
Water purification plants
The ozone treatment process varies according to the purpose of treatment. Ozone injection points are determined by the expected effect or substance to be treated.
- Reduction of THMs
- Improvement in odor and color
- Reduction of organic compounds
- Disinfection
- Removal of inorganic matter such as iron and manganese
Sewage treatment plants
- Disinfection
- Improvements in odor and color
For Industrial Field
Factories
- Reduction of COD(*2)
- Improvements in odor and color
- Decomposition of persistent substances such as endocrine disruptors and medicines
- (*2) COD: Chemical Oxygen Demand
Suitable for application in:
- Dye works
- Oil and gas plants
- Food and beverage factories
- Iron-making factories
- Pharmaceutical plants
- Metal plating factories
- Sugar factories
- Leachate treatment plants
- Pulp and paper plants
...and more
Cooling water for thermal power generation plants
- Disinfection
- Prevention of scaling
Highlights
- Reduction in O&M(*3) costs
- Reduction in blowdown and make-up water
- Ozone is decomposed into oxygen, thus no harmful substances are left or contained in the blowdown water.
- (*3) O&M: Operation and Maintenance
- (*4) PSU: Power Supply Unit
