If you need to sterilize and deodorize space or water, an ozone generator is undoubtedly the best choice. Here are some suggestions to help you buy a suitable ozone generator.
There is testing result of sterilization ability from the International Health Organization: ozone (O3) > hypochlorous acid (HClO) > chlorine dioxide (ClO2) > silver ion (Ag +) > hypochlorite (CLO) > ferrate (Fe3 +) > chloramine (nhcl3).
Ozone is the best choice for sterilization, oxidation, decolorization, deodorization, and it has no residue.
The solubility of ozone in water is between 0.1mg/l-10mg/l. 0.1mg/L is the minimum concentration required for water disinfection and purification, and 2mg/L is the achievable concentration of “ozone water disinfectant”, can use for detoxification, preservation, deodorization and odor removal.
The international conventional standard of ozone for tap water purification is 0.4mg/L, working 4 minutes.
Standards of ozone for different water treatment:
| Item | Dual water supply | Pure water | Natural water | Swimming pool water | RAS water | Food processing water | Waste water |
| Dissolved ozone concentration (mg/L) | 0.1-0.3 | 0.2-0.4 | 0.4-0.6 | 0.2 | 0.1~0.2 | 0.8~1 | 15~20 or more |
| Ozone capacity (g/m3) | 1-2 | 2-3 | 3-5 | 1-2 | 0.5~2 | 5~10 | Need water report |
Standards of ozone for air purification （1ppm=2.14mg / m3）:
Ozone capacity G = Ozone dosage mg/h × air volume m3 / 0.15/1000
| Function | application | Ozone concentration (ppm) | mg/h for each m3 space | Method |
