Urban Sites - Haemers Technologies

NEDER-OVER-HEEMBEEK – BELGIUM

This project was carried out at Haemers Technologies’ headquarters by its own team in Brussels, between March 2020 and March 2021. The contamination was due to a historic motor oil leaking into the soil of an old car garage, now used as the main building of Haemers Technologies. 2 batches of 45 burners each, with various fuel used (propane, natural gas, and diesel) and using the Reburn system 250°C at the cold points Soil targets: TPH (C10-C40) < 300 mg/kg of dry soil Groundwater targets:...

STRASBOURG – FRANCE

This project was carried out under licence in collaboration with the company OGD – Ortec from October 2019 and June 2021. The contamination was due to the discharge of HAP and hydrocarbons (C>12). The soil came from various places along the canal (Citadelle Nord, Ouest and Sud, Starlette Nord and Sud). A thermal treatment platform was set up near the polluted soil, which was excavated and gradually brought to this platform. 41 Natural Gas Smart Burners – Reburn treatment (Vapor Treatment...

PLACE DUMON – BRUSSELS

The contamination was due to the discharge of chlorinated solvents (DCE, TCE, PCE) related to the former dry-cleaning activities in the building. The site was composed of two zones, located in the patio outside the building (25 m²) and located in the basement (17 m²) respectively. The purpose of the treatment was to make a soil and water table treatment with two distinct technologies. The first step was to heat the soil down to the limit of the unsaturated zone to...

Copenhagen – Denmark

The contamination was due to leaks in 5 underground oil tanks inside a basement of an ancient hospital in Copenhagen, Denmark between October 2020 and April 2021. The project is in an urban area, in the middle of the city of Copenhagen with high-level constraints on noise and smells management. 37 Diesel burners – reburn technology. 250°C at the cold points 100ppm (C10-C40) Soil Temperature every meter 4 points from 0 to 3m 2 points from 0 to 5m October 2020 and April 2021 The treatment has been...

Brussels – Belgium

The site was located in a residential area in Brussels. The pollution was caused by the leakage of a buried fuel oil tank. The tank was inerted in 2016. The soil reconnaissance study (2016) and the detailed study (2017) revealed oil pollution in the land surrounding the tank. The polluted area was mainly located in the driveway of a private house and partly under the building. It extended over an area of 28m² and down to 7,5 m below ground. 16...

Beijing – China

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...

Treurenberg – Belgium

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...

Ganløseparken – Denmark

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...

Poggio – Italy

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...

Omovej – Denmark

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:...
