Soil vapour extraction and leachate water treatment at Suvilahti, Helsinki

8.3.2016 virpi

Helsinki’s first industrial area Suvilahti in Sörnäinen is going through a massive change as it is molding into a new residential area after 100 years of industrial use. The new Suvilahti will have apartments, office buildings and parks. Before starting the constructions, the area’s contaminated soil needs to be cleansed from fuels and different sort of industrial chemicals.

Doranova has worked as a subcontractor since 2009 for Biomaa Ltd which is the main contractor in Suvilahti. Doranova is responsible for executing the soil vapor field and pumping station, groundwater treatment and remediation of the water stored inside two old gasometers. The main unwanted substances in the groundwater of Suvilahti area are VOC and PAH compounds. These compounds are removed using activated carbon filtration and oxidation. Also heavy hydrocarbons were found from the two gasometers. These hydrocarbons were separated from the water and transported to toxic waste disposal plant.
