Ozone is sometimes called "activated oxygen". It is the triatomic form of oxygen that we breathe in its diatomic form. Ozone is the second most powerful disinfectant in the world and safely removes bacteria, viruses and odors without residue.
Interestingly, ozone occurs quite frequently in nature, for example, from a lightning strike during a thunderstorm. In fact, that " spring rain" smell we notice after a thunderstorm results from the natural production of ozone. Ozone is probably more familiar in the context of the ozone layer that envelops our planet. This ozone is produced by the sun's ultraviolet rays. It protects us from the sun's ultraviolet rays and acts as a UV filter.
Yes, by the smell. Ozone is an invisible gas with a characteristic smell. A particularly sensitive human nose can possibly detect ozone from a concentration of 0.0076 parts in a million (ppm), but everyone should be able to smell ozone at 0.03 ppm at the latest. In comparison, the air quality limit value for harmlessness is 0.06 ppm. This means that ozone can be smelled before it reaches an unhealthy concentration.
At elevated concentrations above 0.06 ppm, ozone may begin to smell unpleasant to sensitive noses. The big advantage is that no one would voluntarily stay in rooms with elevated concentrations for long periods of time. It would be completely natural to open the window. The smell protects.
Although ozone is a very strong oxidant, it has a very short life span. When ozone comes into contact with odors, bacteria or viruses, they are completely destroyed by the extra oxygen atom. During this process, the extra oxygen atom is also consumed. In addition to the effectiveness of ozone, we also know that it is a safe disinfectant.
The use of ozone is safe because we can smell ozone even in very low concentrations. So if ozone is released during a cleaning, we would notice it immediately because the smell of ozone at a concentration of 1.5 ppm is considered so disgusting that we would not be able to stand it for 5 minutes in such an environment. It is just like entering a room full of smoke.
There are generally two methods to produce ozone. The ultraviolet radiation and the silent electrical discharge. Most use the silent electrical discharge, which basically simulates a lightning strike. Ozone generation using ultraviolet lamps are rarely used nowadays because the process is inefficient. The ozone is extracted from the ambient air.
Practically all areas of application have something to do with cleaning, hygiene, sterilisation, disinfection or odour control in air or water. Therefore, the range of ozone is a large field of application.
Drinking water treatment
Water treatment: whirlpools, swimming pools, aquacultures, etc.
Waste water treatment: textile industry, pharm. industry, sewage treatment plants, etc.
Room air purification: Air disinfection, removal of volatile organic compounds (VOC), e.g. in clean rooms
Odour neutralisation: smell of fire, smoke, cigarettes, corpses etc. in rooms or vehicles, biogas plants, waste management plants, waste rooms, grease separators, fermenters, waste gas purification plants.
Remediation of rooms: mould remediation, odour control
Disinfection of objects, rooms or in washing machines
Production plant cleaning: rinsing and cleaning of production plants, removal of aromatic substances, cleaning of returnable bottles, hygiene measures in the beverage and food industry (dairies, breweries, etc.)
Bleaching of paper and textiles
Deionization of water: e.g. rinsing water in the semiconductor industry
Cosmetics: Skin steaming for cleansing, e.g. with acne
Ozone therapy: therapy method in alternative medicine
Once ozone has been formed by the generator and is discharged into the room, a portion immediately decays back to oxygen. This process is caused by the more natural decay of the chemical instability of ozone. The process just mentioned is accelerated by the presence of walls, wallpaper, etc.
Neutralization of odor by organic material also removes ozone. Furthermore, ozone safely removes batteries through its oxidation reaction. Furthermore, ozone has a short half-life, which means that within a maximum of 30 minutes the ozone content in the treated room is halved. This in turn means that after each additional 30 minute period there will be half as much ozone left as there was at the beginning of the 30 minute period. This is similar to a geometric progression of 16;8;4;2;1. In practice, the half-life is usually less than 30 minutes, due to bacterial and other contaminants in the air. Consequently, ozone, although very powerful, does not last long in indoor air.
Yes! Ozone kills bacteria, fungi and mold spores in the air and on surfaces, eliminating the most common causes of food spoilage. Some foods are treated directly, some are treated only in the surrounding air during storage, processing, protective atmosphere
This depends on the size of the area to be treated and the capacity of the ozone generator. In fact, it is difficult to give an exact treatment duration because different odours can penetrate materials to different depths. This then requires different treatment durations. Please start with small treatment times.
Ozone is very reactive and has a half-life of around 30 minutes. Therefore, the ozone level drops very quickly. It is recommended not to enter the treated rooms for at least 6 hours and to ventilate for another 2 hours.
When treating vehicles, the ozone generator should be placed in the passenger footwell. The ventilation should be set to circulating air and level 1. In the case of a sedan, it is important to fold down the rear seat bench so that the ozone also reaches the trunk. Please treat cars only outdoors with ozone. After the treatment please wait 1 hour and ventilate the vehicle well for 2 hours. Please read the handling instructions for motor vehicles.
