Abstract

La présente invention concerne un MÉSOCOSME simulé permettant de tester la capacité de récupération naturelle d'un sédiment contaminé par du pétrole, qui comprend : un réservoir d'eau de test contenant un sédiment marin ; et une structure de pipeline servant à introduire une quantité prédéterminée d'eau de mer dans le réservoir d'eau de test à un instant prédéterminé, le réservoir d'eau de test possédant un réservoir d'eau d'alimentation situé au niveau d'un côté supérieur de celui-ci et un réservoir d'eau de récupération situé au niveau d'un côté inférieur de celui-ci de telle sorte que l'eau de mer se déplace par gravité. Par conséquent, la présente invention peut résoudre l'inconvénient lié au MÉSOCOSME classique qui est mis en œuvre en extérieur. En particulier, le MÉSOCOSME simulé nécessite au final une main-d'œuvre et un coût réduits et peut être ainsi maintenu même à de faibles coûts de recherche.
