What do you know about ozone generators and ozone dosing data?

Ozone is a strong oxidizing gas, in actual life and production, often used as a disinfectant to use, through the ozone generator, the production of ozone gas, so as to disinfect the air or water. The following Qingdao Aikang ozone generator manufacturers for the majority of users to popularize some common sense about ozone and ozone generator.

1, the specification of ozone generator is divided according to the amount of ozone generation. The units commonly used in ozone production are mg/h, g/h, Kg/h (mg/h, g/h, kg /h), that is, how many weight units of ozone gas can be produced by the ozone generator working for 1 hour.

2, the concentration unit of ozone in the air is ppm or mg/m³; Ozone concentration in water is measured in parts per million or mg/L. Conversion method: 1ppm= 2.14mg /m³ in air; In water, 1ppm=1mg/L. The sanitary and disinfection community is accustomed to using ppm as a unit, that is, one part per million of volume.

3, when ozone reaches a certain concentration in the atmosphere, it will cause environmental pollution. China stipulates: in the residential environment, when the ozone concentration exceeds 0.16mg/m³, it constitutes air pollution (" Indoor Air Quality National Standard "GB/T18883-2002); In the workplace, ozone concentrations above 0.2mg/m³ constitute pollution. Ozone water generator respiratory tract concentration requirements ≤0.16mg/m³.

4, when the concentration of ozone in the air reaches 0.01-0.02mg/m³, people can smell.

5, in the food factory, cosmetics factory, production workshop, warehouse and other places for air disinfection, the concentration of ozone in the air needs to reach 10-40mg/m³ (according to the purification level), and to be closed for 30 minutes. For the surface of the object, it is necessary to reach a concentration of 60mg/m³ or more, and the effect is 1-2h. People should not be on site during disinfection (that is, we often say that man and machine cannot coexist).

6, under atmospheric mixing conditions, when using ozone to sterilize bottled pure water, 1 m/h water usually requires 2-3 g ozone, and the concentration of ozone in water is greater than or equal to 0.4 mg/L. When using ozone to sterilize bottled mineral water, 1 meter/hour of water usually requires 5-6 grams of ozone, and the ozone concentration in water is greater than 0.5 mg/l.

7. When disinfecting pool water with ozone, determine the amount of ozone used according to the hourly water flow rate of the whole pool water during one cycle, usually 1m³/h water uses 1-2g ozone, and then disinfect. When 1m³/h pool water uses ozone ≥4g, the pool water will become clear and blue.

8, Ozone disinfection of aquaculture water is usually determined by the flow rate of each small water, in which half of the pond water is recycled once. Fresh water usually uses 1g of ozone in 1m/h of water, and the amount of ozone in seawater can be increased to 1.5-2g. In the seedling period, the use of ozone can be appropriately reduced. However, no matter how much ozone is used, the ozone content in the water must be reduced to below 0.05 mg/L before the sterilized water is returned to the aquaculture tank.
