The site was in a major former steel and coking factory, covering an area of 8.63 km², located in the west of Beijing (China), for which the industrial activity was stopped in 2006. These types of sites present a big issue in terms of ground pollution, due to the industrial activity, and therefore space reconversion. In this case, the former industrial site is to be transformed into a brand-new park for the next Winter Olympics of 2022. The first phase of...
The site is located in Brussels, Belgium, in the basement of a CBC Bank’s building, near Sainte-Gudule’s Cathedral. The treatment zone is in multiple maintenance rooms with a total of 46m2. The total volume to be treated was of 138m3 (248 Tons) and was mainly impacted by a hydrocarbon’s leakage. Because it was a narrow basement, Engineering and Operations staff encountered difficulties while drilling before placing the Smart BurnersTM. (80cm of concrete floor’s thickness, drilling to 3m depth, low ceiling,..), causing...
The site is located in Ganløseparken in Denmark, over two gardens in a private property. COCs are hydrocarbons from a gasoil tank leak and are located partially under the house below the basement. Treatment goals are defined by local regulation. The total volume of soil to treat was of 1350 m3, at 7.5m depth. Almost every temperature measurement rose above 220°C. The main problematic points are located at 7,5m deep and never passed the 100°C threshold. This issue can be explained...
The site is located in the Refinery of Gela (Italy) that belongs to the Company ENI S.p.A. The treatment takes place in the ex-discharge of the refinery divided in 2 zones, that contained refinery ole fins deposited in the past (called FNP). This area, named Vasca A, is situated within the former landfill sites (also called Vecchie Discariche) in the Isola 32 of the Refinery. The objective of the full project is to treat by thermal desorption the zone for single...
The site was located near to Poggio San Lorenzo (ITALY), alongside a house and a restaurant. By the past, the location was once occupied by a petrol station which spilled diverse contaminants in the ground. The project was made on a 128m² heating zone with 19 gas burners (V5) and 19 secondary heating tubes with a reburn system. The legislation in Italy imposes a concentration of hydrocarbons below 100 mg/kg. However, the targeted concentration of the contaminants at the end of...
The site is located Omøvej 1, 4000 Roskilde, Denmark. It is a private house located in a residential area, West of Copenhagen. Contamination is partially located under the house and mainly in the garden. The target zone is contaminated with mi- neral oil. The average concentration in soil is close to 2750 mg/kg with a maximum concentration of 6750 mg/kg, locally. The total mass of the pollutant into the soil is estimated to 5000 kg. An organic pollution of mineral oil (hydrocarbons:...
The site is in QiLianShan Road 145, Shanghai, China in a 90 000m² field in the city. The location was once occupied by a dying company which spilled various contaminants in the ground. The project is a pilot test on a 25m² at 14m depth (heating zone) with 11 gas burners (V3/V4), a vapor treatment unit and a liquid treatment unit. Construction of the watertight wall In order to isolate the treatment zone from the ground water a wall was built in the...
The site is located at LINDEVANGSVEJ 8, DK 2950 Vedbaek, Denmark. It is a private house located in a residential area, north of Copenhagen. Contamination is partially located by the house under the terrace and mainly in the garden. The target zone is contaminated with mineral oil (C10-C40). The estimation of the diesel amount present in soil are 12000 to 15000 liters and its total mass is estimated to 10800 kg. The soil analysis results showed that the average concentration is...
The project took place in Brussels, in the basement of an office building situated in the heart of the European district. The pollution is due to the leakage of two oil tanks located beneith the underground car park. The soil was polluted with hydrocarbons. An average concentration of 18.000 mg/kg DM. The depth was 14 meters and the total contaminated surface was 50 m². Planning : Mobilization : 4 weeks Treatment : 5 weeks Analyses & reports : 2 weeks Demobilization: 2 weeks The objective of...
The project took place in Denmark, in the city of Alleröd. The site is located in an industrial area, on the grounds of a power station (DONG Energie), under a high voltage transformer. Peak concentrations of chlorinated solvents reached up to 0.38 mg / kg dm, on an area of 36 m2 with a volume of 288 m3. Oil was also detected, with a concentration level up to 15.000mg / kg. The burners were powered by propane. The work was done...
