With the onset of a worldwide pandemic, people are paying close attention to cleaning and sanitising spaces, surfaces and people, and what applications would be effective to do this.

There have been questions asked about the cleanliness of public spaces which are considered high potential areas for bacteria, such as airports.  Another question is whether there is a chemical free way to effectively sanitise them, especially considering the high traffic volumes through them.  

This has sparked interest in Ozonated air purification and water treatment and its application to high traffic areas. 

Ozone in Airports

It has been noted that Singapore’s Changi Airport is one of the busiest airports in the world, who have taken precautionary measures to reduce the spread of COVID-19, including the use of ozone-infused water to disinfect toilet floors, toilet bowls and urinals in bathrooms with particularly high-usage.

Dubai International Airport has what is considered one of the largest HVAC ozone systems in the world with air treatment in all of their buildings. When the building was designed, ozonation was chosen over carbon filtering to purify and freshen the airport air.

The air is injected directly into the central airconditioning systems, and after several years of monitoring the following observations have been made:

  • Passengers and employees noted a pleasing air quality without the distinct stale smells that are associated with busy airports.
  • The savings of ozone replacing carbon filters has been noticeably large. Carbon filters have high replenishment costs and take up valuable space.
  • The energy savings in reducing the makeup air (outside air that replaces air exhausted from inside the building) requirement are significant.
  • Other HVAC system maintenance costs are reduced due to less cleaning of the ducts with virtually no mould and mildew accumulation.

It seems like some of the biggest airports are taking the best measures possible to keep their spaces in tip top shape for those travelling through them.

Ozone applications

But what other uses does Ozone have? What other applications can it be used for?

These kinds of Ozonated air purification systems can be used in homes, offices, apartments, motel rooms, dorm rooms and recreational vehicles. It can also be used in doctors’ offices, hospitals, kennels, motel rooms, medical surgery rooms, or veterinary clinics to sterilize all areas of mould, bacterial and viral contamination. 

Some of the applications can be found below:

  • Bacterial and viral disinfection of both air and water.
  • Filtration aid.
  • Deodorising air and objects, ie. fabric restoration treatments.
  • Oxygen enrichment of water, eg. hydroponics or in agriculture.
  • Industrial wastewater treatment.
  • Scrubbing yeast and mould spores from the air in food processing plants.
  • Treatment of swimming pools and jacuzzi’s.
  • Cleaning and bleaching of fabrics.
  • Sterilising of operation rooms in hospitals.
  • For aquaculture, ie. fish farming and hatcheries.
  • Disinfection of air, destruction of odours and increased production in stock farms.
  • Treatment of air from factories which use animal matter, eg. bones, feathers and skins.
  • Elimination of smells and oxidization of tobacco by-products in air conditioning equipment.
  • Nitrous Oxide oxidation for air pollution control.
  • Disinfection of beverage containers
  • Aiding in processing plastics to allow the adhesion of inks.
  • Improving of health in various aspects.
  • Treatment of grey water to use for gardening.
