Beschreibung
Zusammenfassung:	This disclosure addresses the problem of preventing sediment laden water ("sediment slurry") resulting from hydraulic collection of nodules from the seabed from entering the riser and lift system that carries the nodules to the surface as a slurry. An example includes collecting nodules from the seabed by hydraulic suction, separating the nodules utilizing an inverse hydrocyclone. La présente invention aborde le problème lié à la prévention de l'eau chargée de sédiments ("suspension de sédiments") résultant de la collecte hydraulique de nodules à partir du fond marin, d'entrer dans la colonne montante et un système de levage qui transporte les nodules vers la surface sous la forme d'une suspension épaisse. Un exemple comprend la collecte de nodules à partir du fond marin par aspiration hydraulique, la séparation des nodules à l'aide d'un hydrocyclone inverse.
