Ozone Safety Standard

Ozone industrial hygiene standards:

1#International Ozone Association: 0.1 ppm, the contacting time 10 hours

2#: USA: 0.1PPM;the contacting time: 8 hours

3#: Germany,France, Japan: 0.1PPM

4#: China: 0.16 mg/m3

The home ozone disinfection ozone leakage outside the cabinet must not exceed 0.2mg/m3 (1.5 m away), disinfection residual concentration after a period not more than 0.2mg /m3.

Animal tests showed that the ozone concentration of the starting point of toxic 0.3ppm, and people can smell of ozone concentration 0.02 ~ 0.04ppm. According to the toxicity of ozone onpulmonary function test results, the 1.5 ~ 2.0ppm ozone concentration allowed limit. Ministry of Health provides the maximum allowable concentration of ozoneis 0.2mg / m3.

Generally, the main application ofozone determined the ozone output; divided into gaseous and liquid sterilized;

Basically, the different source feeding will affect the ozone gas concentration, output, and Purity.Gas source is generally divided into ordinary air, dry air source, the source of oxygen-rich and oxygen gas source four kinds of industrial;

The above gas source based on the same equipment, the ozone concentration and output will be ascending order.Generally speaking, it should not be configured ordinary gas source, as this would affect the life of ozone generator and lead to instability.According to the purpose an application, the common gas source can be roughly divided into the following catergories:

 Dry air source

Air disinfection, tap water treatment, swimming pool, aquaculture, water production cycle, reclaimed water;

Oxygen-rich source

The application need higher ozone concentration such as: purified waterplant, mineral water,waste water treatment, medicine and food processing workshop.

Industrial oxygen source

Require the higher purity, higher concentration ozone, a small ozone output

Disinfection applications for large scale space such as: medicine and food processing workshop. Generally, to install special pipes in the workshop, make the ozone gas well-distributed, and passing through the central air-conditioning duct pipe, but it will result in air-conditioning duct corrosion of metal parts and ozone depletion.
