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...
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...
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...
During the US-Vietnam War, millions of liters of herbicides were dropped over Vietnam: The Rainbow agents. Agent Orange was proven to cause severe health issues, including birth defects, neurological problems and cancers. More than four decades after the Vietnam War ended (in 1975), the stability and bioaccumulation of dioxins - originating from agent orange - still affect the inhabitants. The Center for Technology Environmental Treatment/Chemical Force (CTET/CF), the GAET Corporation and HAEMERS Technologies SA agreed to establish a joint operation to...
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:...
Historical or accidental pollution, mainly heating oil tank leakage or leakage of service station petrol/diesel. Heating oil. Fuel: diesel, petrol Spills ranging from a few m3 to several tens of m3 near or under the storage tanks. Installation of small pumping units DS 500-6/125 or DS 100 – 5 linked to skimmers SKIM 2-25 or SKIM 4-25. Pollutant Hydrocarbons Nb of Wells / Depth Variable Pumping Unit DS 500-6/12 (ATEX) DS 100-5 (ATEX) Skimmers SKIM 2-25 SKIM 4-25 Location Angleur, Belgium
Historical pollution in a petrochemical unit. Mainly hydrocarbons, BTEX, aromatic and aliphatic compounds Presence of a free phase ranging from a few centimetres to several tens of centimetres on a fairly extensive surface. Industrial zone near a river with strong level variations. Average depth of aquifer 12 m below ground level. 2.5 m groundwater variability, fast and induced by the level variations of the nearby river. Given the scope of pollution, installation of two pumping units DS 500-6D ATEX, equipped for pumping at a depth greater...
Historical pollution: leakage in tanks of a chemical plant. The product has a high viscosity (honey or semi liquid tar type) and crystallizes in cold weather. On a surface of a few acres, a floating layer of chemicals and hydrocarbons with a free phase thickness of up to 7 m originally. Agricultural zone Limestone (chalk) Average depth of aquifer 22 m below ground level Seasonal variability of aquifer between 2.5 and 3.0 m over the year ODSI’s solution was implemented after encountering many difficulties using other methods...
Crack in the filling conduit of storage tanks. On a surface of a few acres, a diesel free phase of a few centimeters, with a migration of the free phase towards the nearby canal. Along a canal Fill, sand, silt, clay and rocks Average depth of aquifer 4.0 m below ground level Variability of aquifer +/-1 m Emergency response shortly after discovering the incident. Delivery and implementation of a pumping unit DS 500-12 accompanied by a 1m3 outdoor storage IBC. Placement of a floating dam on the canal...
Historical pollution. Leak in a set of diesel storage tanks protected by a concrete holding tank containing all storage tanks. On a surface equivalent to a football field, a free phase of diesel, a few centimeters to tens of centimeters thick, located under and outside the holding tank, on the side of the aquifer discharge. Along a sea access canal, with small level variations in the canal Sand Average depth of aquifer 2.3 m below ground level Seasonal variability of aquifer between 50 and 70...
