Former Steel and Coking Factory Reconversion for 2022 Olympic Games in Beijing, China

Former large industrial sites are often subject to closure or relocation, especially when situated in urban areas. It was the case of 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 [...]

Oxydation Thermique Des Gaz

Le traitement thermique des sols contaminés par des composés volatils et semi-volatils génère indubitablement des vapeurs, des gaz et des liquides (condensat). Une fois récupérés à la surface, ces produits nécessitent un traitement ad hoc. L’oxydation thermique dans un dispositif adapté est l’une des méthodes utilisées par Haemers Technologies pour la destruction de substances dangereuses présentes dans ces effluents. Les conditions opératoires d’une oxydation thermique varient en fonction de la nature de la substance dangereuse : Pour les hydrocarbures, la température [...]

Here’s what you missed at AquaConSoil 2019

The 15th International Conference on Sustainable Use and Management of Soil, Sediment and Water Resources was held from May 20 to 24 2019 in Antwerp, Belgium. HAEMERS Technologies was represented by several of our engineers and team leaders. Some of our latest abstracts were selected for the conference, and were presented during the week. One of them was displayed as a poster. If you missed the event or would like to see the presentations again, all of them can be found on [...]

Meet us at AquaConSoil 2019 on 20-24 May, 2019

Haemers Technologies will be present at AquaConSoil 2019 in Antwerp, Belgium! What is AquaConSoil?

Service écosystémique des sols, pourquoi les préserver ?

Depuis des dizaines de milliers d’années, l’Homme exploite les sols pour assouvir ses besoins. Au fur et à mesure du temps, la présence de l’Homme sur Terre s’est amplifiée et ce de manière exponentielle. Par conséquent, la pression exercée sur les sols s’est accentuée, se manifestant de manière toujours plus violente. Les sols, interfaces et liens entre la biosphère, l’atmosphère, l’hydrosphère (Ruellan, 2010), ont un rôle majeur au niveau du fonctionnement de notre planète. En les modifiant, les sociétés [...]

International Women’s Rights Day at Haemers Technologies

I studied Bio-Engineering. I think that in the auditoriums we were a majority of girls, I would say 60%. After graduating from university, I found myself in a soil remediation engineering office, it is true that the number of girls has drastically decreased. Nevertheless, I worked in the office, I did some work on site. I found myself on a site surrounded by men, to sometimes have to take charge of things, and it went extremely well. I really [...]

Case Study For The In-Situ Treatment Of Unsaturated Soils At Gela’s Refinery (Italy)

By K. PACELLA, H. SAADAOUI, J. HAEMERS. HAEMERS Technologies © G. CACCAMO, A. BARABESI. Simam S.p.A., Servizi Industriali Manageriali Ambientali, Senigallia, Icaro Ecology S.p.A. The site interested by the remediation process through the application of the In-Situ Thermal Desorption technology, located inside the Refinery of Gela (ENI Group), consists of former discharge for oil residues deposited in the past. The contaminants are light and heavy hydrocarbons, benzene, polycyclic aromatic hydrocarbons, chlorinated compounds and mercury. The treatment area is divided into 24 batches: [...]

In Situ Thermal Desorption under a building, in the center of Brussels

Nowadays, urban soil is a natural ressource to preserve. Indeed, the fast urbanization of the recent years led to considerable consequences in terms of space and energy consumption as well as water and soil pollution. At the present time, urban areas contain many contaminated sites. Two main issues can be identified which would need to be addressed through further reflection: first, the space consumption. Polluted areas in the centre of the cities are a waste of space. The clean-up of [...]

Laboratory tests and pilot conception at Biên Hòa Airbase, Vietnam

During the US-Vietnam War, millions of litres of herbicides were dropped over Vietnam: The Rainbow agents. Biên Hòa Airbase was a joint operating base for the South Vietnam Air Force and the United States Air Force where thousands of barrels of Agent Orange were stored. Agent Orange was proven to cause severe health issues, including birth defects, neurological problems and cancers. Agent Orange is a mixture of 2,4-dichlorophenoxyacetic acid and 2,4,5-trichlorophenoxyacetic. Traces of dioxins were also found in some Agents. [...]

Thermal Conductive Heating (TCH): electrical resistance heating or gas fired burners

Thermal desorption is an environmental remediation technology that uses heat to increase the volatility of contaminants (organic and/or inorganic) as such that they can be removed from solid matrix (typically soil) to be recycled or destroyed. The subject will focus on two existing in situ TCH techniques: electrical and thermal heating. The designs and calculations are made considering the injection of power per linear meter of heating element. The method of heat injection with electrical power directly injects 1 kW/m, [...]
