Abstract:
The invention relates to a method for the containment of pollutants present in the aquatic environment and to a device for implementing same. According to the invention, a containment material (7) is poured over the pollutant (1) in order to cover same, said method comprising the following steps, namely: i) the in situ measurement or documentation of the surface and subsurface currents and assessment of sporadic events, such as storms, that affect the location of the pollutant (1) to be covered; ii) selection of the minimum grain size of the containment material (7); iii) determination of the amount of containment material (7); and iv) deposition on the pollution source of the containment material (7) formed by at least one continuous layer of sepiolite clay (2) having a sepiolite mineral content of between 25 and 100 %. In addition, a layer of granular material (3) can also be deposited thereon, said layer representing up to 99 wt.- % of the containment material (7). The device includes a rigid tube (5) which can be extended using a flexible tube (10) which is divided into sections that are separated by metal rings (9) supported by a steel cable (8).

Abstract:
Consistente en cubrir un contaminante (1) mediante el vertido de un material confinante (7), de la siguiente manera; i) Medición in situ, o documentación, de las corrientes superficiales y profundas y consideración de eventos esporádicos tales como tormentas, que se producen en el área de emplazamiento del contaminante (1) a cubrir. ii) Selección del tamaño mínimo de grano del material confinante (7). iii) Determinación de la cantidad de material confinante (7). iv) Depósito sobre la fuente de contaminación del material confinante (7) constituido por al menos una capa continua de arcilla sepiolita (2), con un contenido en mineral de sepiolita entre el 25 y el 100%. Adicionalmente, puede depositarse una capa de un material granular (3), suponiendo hasta un 99 % en peso del material confinante (7). El dispositivo incorpora un tubo rígido (5) que puede prolongarse en un tubo flexible (10) dividido en secciones separadas por anillos metálicos (9) soportados por un cable de acero (8).
