Ozone has oxidation, sterilization, decolorization, flavor removal four strong oxidation effect, and is widely used in major industries. In fact, for the dosage of ozone application, the national Ministry of Health has formulated standards in some cases, and through our practical application summary, we can only boil down to the following data:
Relatively clean water, ozone dosage is 0.5 ~ 1.5g/m3;
For drinking water with serious pollution, the dosage of ozone is 3 ~ 6g/m3;
For all kinds of sewage treatment, ozone concentration is 30 ~ 250g/m3.
Ozone can kill or destroy all the microorganisms and their bacteria, and can remove and degrade harmful substances to improve the quality of drinking water, effectively avoiding the chlorination of organic chlorides and other carcinogenic substances.
For ozone dosage in common application areas, the following are references:
| Application | dosage | Remark |
| Secondary water supply for water tank | 1~2g/m3 | Regular use |
| Mineral water purified water | 2~2.5g/m3 | Uninterrupted use |
| Pool circulates water | 2g/m3 | Regular use |
| Water supply from waterworks | 1~2g/m3 | Use with chloramine |
| Well water | 3g/m3 | intermittent service |
| Hospital sewage discharge | 10~30g/m3 | Regular use |
| printing and dyeing wastewater | 10~20g/m333 | Use with biological aeration filter |
| Pretreatment of pharmaceutical and chemical wastewater | 40~200g/m3 | Uninterrupted use |
| Denim decolorization | 50~300g/m3 | According to the number of clothes |
| Office and residential space | 0.1~1ppm | 40 minutes/day |
| cold storage | 1~2.5ppm | intermittent service |
| Food workshop disinfection | 5~10ppm | 40 minutes/day |
| Medical workshop disinfection | 10~20ppm | 40 minutes/day |
