Due to the Budapest Airport’s environmentally conscious attitudes, several improvements have been made in order to protect the natural environment around the airport. In the frame of this initiative the stormwater treatment of the airport’s paved surface with polluted river channels was developed, and an accident emergency system was created. In order to clean the contaminated stormwater; nearly thirty open trench ENVIA TRP sludge and oil separation equipment were installed. Pureco Ltd. is proud of this successfully completed project – due to the diversity of the project the knowledge, experience and collaboration of several other divisions of the company, from design, through licensing, to the product supplies and logistics, was needed.
