The best ozone solutions for air & surface disinfection
Microorganisms cause issues in various places, in a clinical setting bacteria can cause dangerous outbreaks. Ozone can be used as a chemical disinfectant to kill bacteria and viruses with low ozone concentrations.
Effective bacteria reduction with ozone
For many applications a bacteria reduction of 99.99 % which corresponds to a 4 log reduction is sufficient, for a higher deactivation grade the solution is easily adapted to provide higher concentrations and exposure time, in adapted solutions even bacteria spores can be treated. The figure above applies for treatment in rooms and ventilation ducts, we have used ozone to limit the spread of airborne microorganisms in food industries and food storage.
Air disinfection in the food industry
In food applications, the migration of microorganisms within the plant accelerates the molding process. However, when integrating the ozone treatment with our RENA Pro, the molding process can be effectively reduced without causing any harm to the food production. Ozone has proven to be highly effective in sanitizing equipment within the dairy industry, providing excellent results while eliminating the necessity for harmful chemical disinfectants.
Air disinfection in hospitals and health facilities
Unlike the food industry, where room treatments are often neglected, hospitals have stringent cleanliness standards and already implement frequent cleaning practices to minimize pathogen transmission. This typically involves regular surface wiping using chemical disinfectants. While traditional manual cleaning and disinfection practices have been deemed acceptable, it has been observed that they are often suboptimal and time-consuming.
In a hospital setting such discrepancies increases the risk of pathogen spreading between areas and patients. Automated non-touch technologies are good additions to cleaning practices as it adds another layer of cleaning. (Boyce, 2016)
Ozone compared to other treatment methods
Non-touch technologies include the usage of UV-lamps and chemicals dispersed as an aerosol or gas which deactivates microorganisms. Compared to other treatment methods for air disinfection, ozone can efficiently disinfect large air volumes, neutralizing micro-organisms, including viruses. This makes it ideal for use in medical applications, for example in hospitals or doctors waiting rooms.
An important factor that enables savings is the time the cleaning agent can actively deactivate bacteria, as compared in the figure below:
The diagram show that the contact times varies greatly, UV cleaning systems often have a very short time window to irradiate the air and therefore needs to add a lot of energy to ensure sufficient deactivation in this short time, wiping with a cleaning solution is limited by the time it takes for the surface to dry while ozone will continue to attack bacteria until it naturally decomposes or is removed. The use of ozone significantly increases energy savings.
Ozone is generated on-site as needed, eliminating the need for additional resources involved in handling and storing hazardous chemicals. Ozone naturally decomposes to oxygen after treatment, leaving no chemical residue behind.
In terms of usage, the distribution of ozone as a gas enables it to reach hard-to-sanitize surfaces, accessing spots that are difficult to wipe. Studies have shown that low ozone concentrations are capable of deactivating bacteria and enveloped viruses by reacting with unsaturated fatty acids in the plasma membrane, certain surface proteins, and DNA. However, dealing with stable viruses and bacteria spores requires higher concentrations of ozone in conjunction with air moisture over extended periods of several hours.

Reducing the risk of spreading pathogens
In a clinical setting, ozone generators can reduce the risk of pathogens spreading when new patients enter previously occupied rooms, it can also be used after traditional cleaning to reduce the risk of disease spreading from infectious body fluids left by the previous patients.
Depending on customer need the treatment time and ozone concentration is adapted to the desired log reduction. After the finished treatment ozone either decomposes into oxygen naturally over several hours or the decomposition is accelerated significantly with the use of ozone destructors.
For clinics that are closed during the night, ozone treatment can be scheduled in waiting rooms, corridors and bathrooms giving plenty of time for treatment and ozone destruction before the first employee enters.
For surgery rooms or other areas that need a 6 log scale deactivation of bacteria, viruses and even spores, specialized solutions using high concentrations of ozone in a sealed room over several hours is necessary. The sanitation process can be started from a panel outside the room, and information regarding remaining time is displayed. Once the set time is over, the ozone is destroyed with an ozone destructor.
