About Ozone treatment

Application

The ozone gas has so strong oxidizing power that it is used for sterilization, deodorization, bleaching or other purposes. The ozone gas has several advantages such as simplification structure of the ozone gas decomposer and has been used in many fields because it can be decomposed into oxygen by itself.
Examples of use are below.
1. Advanced water treatment at the waterworks (mold odor removal)
2. Sewage sterilization and waste water treatment from various plants (COD and BOD reduction)
3. Sterilization of the water used at the aquarium or the fish farm
4. Sterilization of the water used at the pool, the bath, the gym or so on
5. Sterilization and cleaning of food-related fields
6. Sterilization and cleaning of medical-related fields
7. Air (indoor) deodorization and sterilization
8. Pulp bleaching (Decolorization)
9. Ballast water (vessels) treatment
10. Cleaning in the field of electronic devices manufacturing

Principle of ozone gas generation


Silent discharge


The ozone gas is generated by applying high-voltage through dielectric between electrodes and supplying air or oxygen. The electrode structure is circularity and creeping discharge, and the ozone gas can be generated from low concentration to high concentration, however, the concentration is subject to change, depending upon voltage, cooling system, electrode structure, raw gas or so on.


Electrolysis


Being a method for generating ozone gas by electrolyzing ultrapure water, it enables obtaining ozone gas with high concentration (14 wt. %) and high purity - without metal impurities and particles, by employing IEMs and anodes with catalyst for generating ozone gas. At the same time, high purity H2 gas is generated as well, therefore effective use of hydrogen gas is also possible.
