Selection of O 3 concentration and ozonator work time
Choosing the right ozone concentration is a task for a professional who alone determines the efficiency of the ozonator and the duration of the procedure, and thus the ozone concentration in the room based on knowledge, practice and own observations. Ozonator working time incl. depends on the type and amount of pollution removed (different odors, microorganisms and other pathogens have different ozone resistance), capacity of the ozonated room as well as temperature and humidity. Oxygenation or reduction of air humidity in the room atmosphere is often needed before ozonationrelative humidity: 30 - 60%
Ozone concentration and its measurement
Ozone concentration is measured by a special meter that shows the amount of ozone particles in air or water. The measured value is displayed in units of ppmThis concentration is a derivative of a molar fraction and determines how many molecules of a chemical compound fall into 1 million molecules of solution .ppm = mg / l ppm = mg / m31 ppm = 2.14 mg O3 / m3half-life of about 20-30 minutes
The duration of the procedure depends on the ozone concentration achieved.Recommended concentration min. 1,5ppm3h at a concentration of 2ppm2h at 3ppm1.5h at 5ppm
Ozone concentration (mathematical calculation)
How to calculate what concentration we will reach afterhour generator operation with efficiency7g / h in a 100m 3 room ?Within 1 hour, a total of 7000mg of ozone will be produced.7000mg / 100m 3 = 70mg / m 3The half-life is about 20 minutes, so we divide the result by 3.70 / 3 = 23.3 mg / 0 323.3 / 2.14 = 10.74ppm
Ozone concentration in practice
In the practice of working with ozone, it is often the case that ozone concentrations in similar volumes come out differently due to the different conditions in the ozoned rooms, such as temperature, humidity, textile materials in the room and other factors responsible for faster ozone decomposition.
Ozonation without a meter
If we do not have an ozone concentration meter, we can estimate the ozonation time approximately, e.g.For a room of 8 x 4 x 2.6 = 83.2 m 3
Purpose - to refresh the room
Time - 30 min (DS generator 7)
Time - 15min (generator DS. 14)
We should ozonate the same room with a bothersome much longer.
Purpose - to remove the smell
Time - 1-2h (DS. 7)
Time - 45min - 1.5h (DS. 14)
If the smell is still noticeable, the treatment should be repeated.
