The water dissolved with O3 for application use is regarded as the “almighty water.” It has been used in water purification plants for over a century and it is highly stable. O3 will break down into gas after reaction and there is no concern of any residue and it is highly safe. The safety regulation of the U.S., Europe, Japan and Taiwan towards concentration of O3 in the air is 0.1ppm. The patented technology of Bright Ozone has enabled the concentration of ozone dissipated in the air below 0.01ppm.
Under the standard of O3 with 0.5 PPM concentration, 20°C, E. Coli can be totally eliminated in 5 seconds.

| 1886 | The earliest record of using ozone to sterilize in the history was France. |
| 1893 | A Dutch drinking water plant firstly used ozone in water treatment. |
| 1940 | There are over 100 water plants using ozone to sterillize. |
| 1980s | There are already 1,200 water plants using ozone to sterilize (Europe accounted for 80%). |
| 1997 | The US Food and Drug Administration ( FDA ) approved the application of ozone sterilization in bottled water and its production line. |
