Commercial Airports

The air traffic is poised to grow further with the economic activity and demographic growth: the growing middle-class is stimulating airline activity. Many airlines have started operating cheap flights and the growth continues at a rapid pace today, although it is less hectic. It is not without consequences of the quality of the air at the airport location and the immediate surroundings of the airport buildings-hotels, office buildings…

Airplanes play a vital role and is responsible for air pollution inside the airports. The road traffic around these places is quite dense and the buses and trucks on the ground to support the loading operations of passengers and goods also contributes its part to the air pollution problem. The main source of pollution is of a particulate nature: jet engines emit fine particles in their combustion emissions. Other gaseous pollutants can also affect air quality and health: hydrocarbons, acetaldehydes, nitrogen oxides (NO, NO2, NOx), but also ozone. Other sources of air decay are added in buildings: odors and smoke from the restaurant areas, aldehydes of various types.

The major airports, which in fact exhibit a higher-than-average level of air pollution, are working on reducing air emissions, but also on improving indoor air quality. For the interior, some of them are involved in a sustainable development process have equipped themselves with ventilation and air conditioning systems that filter out harmful pollutants.

The air handling units ventilate and are equipped to remove fine particles that are invisible to the naked eye (PM1, PM2.5, PM10). They can be also be equipped with activated carbon filters to eliminate molecular contamination.
