Title
(EN) METHOD AND APPARATUS FOR REMEDIATING CONTAMINATED MATERIAL
(FR) PROCEDE ET APPAREIL DE TRAITEMENT DES MATERIAUX CONTAMINES
Abstract
(EN)
The apparatus (10) of the present invention includes a tank (12) containing a cleaning fluid (112) having microorganisms therein. The material to be cleaned (92) is placed within the tank (12) and the microorganisms separate the contaminates from the material to be cleaned (92). The cleaning fluid (112) is recirculated continuously through the cleaning tank (12) and the contaminates are drawn off of the fluid within the container (13) as the contaminates rise to and float upon the top surface of the fluid (see 114) within the container (13).
(FR)
L'invention concerne un appareil (10) comprenant une cuve (12) contenant un fluide de nettoyage (112) dans lequel sont placés des microorganismes. Le matériau à nettoyer (92) est placé dans la cuve (12) et les microorganismes séparent les produits contaminés du matériau à nettoyer (92). Une recirculation continue du fluide de nettoyage (112) est assurée dans la cuve de nettoyage (12) et les produits contaminés sont attirés hors du fluide dans le conteneur (13) au fur et à mesure qu'ils s'élèvent et flottent sur la surface supérieure du fluide (voir 114) dans ce conteneur (13).
