In-Situ Thermal Desorption - Haemers Technologies

SITE UPDATE : STRASBOURG, FRANCE

🔝 We have started the treatment of the 4th pile on our site in Strasbourg, France. ✔️ We are applying Ex-Situ Thermal Desorption (ESTD) to remediate the soil contaminated with Hydrocarbons and Polycyclic Aromatic Hydrocarbons (PAHs). 🌡️ The desired treatment temperature is 250°C. 77 burners are heated to treat 2000m³ of soil. We have introduced a system of continuous monitoring of stack emissions. As soon as we approach the threshold, an alert is triggered, enabling us to take immediate action to resolve the...

SITE UPDATE : ETTERBEEK, BELGIUM

🔝 We have finished the treatment on our site in Etterbeek, Brussels. ✔️ We were applying In-Situ Thermal Desorption (ISTD) to remediate the soil contaminated with Hydrocarbons (C10-C40). The pollution was located in the cellar of a private home. 🌡️ The desired treatment temperature was 220°C and 4 burners were heated during 37 days to treat 20m³ of soil. 🤝 We were working on this project site with

QUAREGNON – BELGIUM

The project is located in Belgium (gps coordinates: ‘50.434913n, ‘3.85913e). The domestic fuel oil tank leaked and contaminated the ground under the cellar and next to the house in the garden with hydrocarbons. The site is divided into 2 parts, one part under the house in the cellar, and one part outside in the bore designed to place the oil tank. The house will still be inhabited during the works of depollution in cellar where 4 burners have been placed. the...

BONHEIDEN – BELGIUM

The site is a disaffected building which faith is to be rebuild for housing and is contaminated with chlorinated solvent. The contamination has been emitted by an aluminum refining process. The site is composed of two distinct rooms for a total of 60m². A 2m soil layer has been excavated from one of the rooms and then has been backfilled with sand cement/concrete. Even there’s a 2m layer of clean soil, for such shallow depth, the heat has to start...

Japanese Knotweed treatment by Thermal Desorption

HEERLEN – THE NETHERLANDS

The infested materials at the treatment site contains Japanese knotweed rhizomes, known as a parasitic plant species in Europe. The site is located on the roadside in the municipality of Heerlen in the Netherlands where a small plant of Japanese knotweed was growing. The treatment objective is to reach a certain temperature to prevent the growth of new plants through these rhizomes and stop its invasion. There are two specificities in this project: no vapor tubes since no polluted vapor and...

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:...

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...

Sambreville – Belgium

We are carrying out a study to clean up materials from the screening of construction waste by Bruco. These materials are composed of small organic waste, PVC, plastic, insulation, polystyrene, etc. The objective of this project is to analyze the ability of thermal desorption to clean up these materials containing construction waste. Organohalogens are organic chemicals that contain one or more bonds between carbon and a halogen (chlorine, bromine, fluorine, iodine). EOX (Extractable Organohalogens) are the organohalogen compounds that can be extracted...
