Tiivistelmä
Urban stormwater treatment methods have been studied for many years. However, research about the treatment solutions for airports in winter condition countries is still limited. This thesis project deeply analyses the existing stormwater treatment practices for the airports, and specifically proposes the most suitable one for airports in winter condition countries, taking Helsinki-Vantaa International Airport as a case study.
In this thesis project, the crucial parameter, which majorly affect the efficiency of a treatment approach, such as rainfall intensity, temperature and airport conditions are obtained from the Finnish Meteorological Institute and other scientific resources. A comparison between the methods based upon several criteria namely the amount of rainfall, local condition, requirements and applicability, is carried out using the real data.
The findings from this thesis show that a combination of hydrodynamic separator as a primary treatment and media filter, infiltration device or porous pavement as a secondary treatment are applicable in the airports. Further study will be conducted in the future to design a highly effective stormwater treatment system in airports in winter condition countries.
