Title
(EN) PREPARATION AND CONDITIONING OF SEDIMENTARY MATERIALS
(FR) PRÉPARATION ET CONDITIONNEMENT DE MATIÈRES SÉDIMENTAIRES
Abstract
(EN)
A flexible process for the preparation and conditioning of sedimentary materials. The degree of decontamination of these dredged materials is enhanced by the use of chemical indicators. Based upon the level of contamination contained within this material the process is used to isolate the specific contamination and utilize a variable process to decontaminate these compounds. Not all of the compounds contained within the dredged sediment is treated the same way. The process is designed to isolate the composite of materials and treat each particle with a different process based upon its classification. Post treatment, this material may be combined and dewatered for a suitable use.

La présente invention concerne un procédé souple de préparation et de conditionnement de matière sédimentaires. L'utilisation d'indicateurs chimiques permet d'accroître le degré de décontamination de ces résidus de dragage. En fonction du degré de décontamination présent dans la matière, le procédé sert à isoler une contamination précise et utiliser un traitement variable afin de décontaminer ces composés. Tous les composés contenus dans le sédiment dragué ne sont pas traités de la même manière. Le procédé permet d'isoler les éléments composites de la matière et de traiter chaque particule à l'aide d'un traitement différent selon sa classification. Une fois le traitement fini, cette matière peut être associée et déshydratée en vue d'une utilisation appropriée.
