Viruses and bacteria - spread of infection

Many bacteria and viruses spread through the air we breathe. There is a distinction between airborne infection and drip-borne infection.

Airborne infectious agents are small particles that float in the air and reach the airways via the breathing air. However, the most common transmission route via the airways is drip infection, i.e. infectious agents accompany the thousands of small drops that are created when coughing and sneezing.

Infectious agents can also stick to surfaces and move from surface to surface. The more people who touch a surface, the greater the risk that infectious substances will end up on the surface and then also be passed on. A good example is passing from a hand to a door handle or faucet to someone else's hand. That is why we are asked to wash our hands frequently and carefully.

Some infectious agents can survive for several days on the surfaces where they have ended up and can keep spreading the disease. On cold metal, infectious agents can survive for as long as three days.

Most viruses, bacteria and microorganisms can be killed or inactivated by disinfectants. Ozone is one of the strongest disinfectant available.

The advantage of ozone is that it is easy to disinfect both air and hard-to-reach surfaces. Ozone, which is already gaseous under normal ambient conditions, is simply mixed with the air in the room and thus rapidly breaks down and inactivates harmful microorganisms, viruses and bacteria in the air and on surfaces, even on surfaces that are normally difficult to reach.

How effective (degree of killing or deactivation) and how fast the disinfection is, depends on the dose applied. The dose is a function of concentration of ozone and the exposure time (CT value). There are different types of bacteria and viruses. They differ in how resistant they are to disinfectants.

Increased ozone concentration results in increased killing of viruses while reducing the necessary treatment time.

The eight-hour exposure limit for ozone for people in a workplace is generally 0.1 ppm and is regulated by local laws and authorities. For ozone disinfection, the concentration exceeds 0.1 ppm, therefor you shouldn’t enter ozone-treated rooms. Afterwards, you must also make sure that all excess ozone is removed by ventilating the room before entering. This is most easily done by opening windows or if not possible, let the ventilation work for half an hour.

Ozone degrades quickly and inactivates harmful viruses and bacteria in the air and on surfaces, even on surfaces that are normally difficult to reach.

The only requirement is that the treated air/surfaces are enclosed in a room. Remediation of viruses and bacteria can be used, for example, in hospitals and health care facilities, in buses, taxis, trains, schools, ambulances and restaurants.

Ozone purification with ACT-3000

How much ozone is needed and how long the ozone production must run is depending on the room volume and how mush viruses and bacteria there is to break down. The treatment time can vary from one hour to over 10 hours, and you can treat during the night when the business is closed.

Treatment can be repeated as often as needed. ACT-3000 is easy to use and the operating cost is minimal.

ACT-3000 is developed and manufactured in Sweden by Ozonetech. Our large custom-made system solutions for air and water purification are found worldwide in industries, wastewater treatment plants, yeast factories, pharmaceutical industries, breweries, greenhouses and shopping centers. We are fast growing and multiple award-winning.

ACT-3000 / 3000P is developed for professional cleaning and disinfection in industry, service sector and municipal operations.

Easy treatment, do this

1. Position the ACT-3000 in the room, preferably higher (in an elevated location)
2. Close doors and windows
3. Connect ACT-3000 to electricity
4. Choose ozone production 1-100%
5. Leave the room and close the door
6. You decide for yourself how long the treatment will last
7. When you want to end the treatment, enter the room and turn off the ozone generator. Open the window to extract any excess ozone faster. Step out of the room and close the door to let the rest of the ozone oxidize
8. Tip: It is convenient to control the treatment using a plug-mounted timer
