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|
|Disinfection and Sterilization||Medical tools||20||50-100|
|Detoxification and Preservation||Normal place||1-2||2.5-5|
|Deodorization and Purification||Morgue||3||7|
|Fatty acid factory||10||25|
|Wastewater treatment plant||1-2||2.5-5|
