How to choose an appropriate ozone generator?

How to choose Ozone generator ?

1. The ozone generator is divided by the weight of the ozone generator. The unit of ozone production is mg / h or g / h (mg / h, g / h), that is, how many weight units of ozone can be produced by the ozone generator working for one hour.

2. The concentration of ozone in water or in mg / m3 is the unit of ozone. Conversion method: 1 ppm = 2 mg / m3 in air and 1 ppm = 1 mg / L in water.

3. When ozone reaches a certain concentration in the atmosphere, it will cause environmental pollution. Our country stipulates that in the living environment, when the ozone concentration exceeds 0.15mg/m3, it will constitute air pollution; in the workplace, when the ozone concentration exceeds 0.2mg/m3, it will constitute pollution.

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

5. When disinfecting the production workshops of food factories, pharmaceutical factories and cosmetics factories, the ozone concentration in the air can reach 10-20mg / m3 when the cleanliness of the workshop is not more than 300000, and the ozone concentration should be 20-30mg / m3 if the existing equipment and articles in the workshop need to be disinfected at the same time; If it is to disinfect the workshops with 100 000, 10 000 and 100 grade local cleanliness, the ozone concentration should reach 30-100 mg / m3. When the packaging materials are fumigated with ozone, the ozone concentration in the air in the disinfection room / cabinet is generally between 50-200mg / m3; when the raw fish fillets, shrimps and other aquatic products are soaked in ozone water, the ozone concentration in the water is generally between 0.8-1.0ppm.

6. When bottled pure water is disinfected with ozone at normal temperature and normal pressure, 3G ozone should be used for 1m3 / h water, and the ozone concentration in the water should reach or exceed 0.3mg/l; for bottled mineral water, 6G ozone should be used for 1m3 / h water, and the ozone concentration in water should reach or exceed 0.5mg/l.

7. When ozone is used to disinfect the water in swimming pool, the amount of ozone is determined according to the water flow per hour when the whole pool is circulated once. Usually, 1-2g ozone is used for 1m3 / h water, and then a small amount of disinfectant is added. When 1m3 / h pool water uses 4G or more ozone, the pool water does not need to add disinfectant, and the pool water will become clear and blue.

8. When the aquaculture water is disinfected by ozone, the amount of ozone used is usually determined by the hourly water flow when half of the pool water is recycled once. Fresh water is usually 1m3 / h, and 1g ozone is used for water. If it is seawater, the ozone amount can be increased to 1.5-2g. During the seedling stage, the amount of ozone used could be reduced. However, no matter how much ozone is used, the ozone content in the water must be reduced to less than 0.05mg/l before it is returned to the aquaculture pond.
