Abstract

Des dispositifs d'alimentation classiques pour des organismes en haute mer présentent comme problème la difficulté de contrôler la quantité d'oxygène dissout dans l'eau. A cet effet, l'invention porte sur un dispositif de commande (2) pour contrôler la quantité d'oxygène dissout dans l'eau dans un réservoir d'eau, lequel dispositif comprend : une pompe à air qui fournit de l'air au réservoir d'eau ; une trajectoire de circulation qui retire de l'eau vers l'extérieur du réservoir d'eau et qui renvoie celle-ci au réservoir d'eau ; une pompe d'alimentation par pressurisation pour amener l'eau à s'écouler à travers la trajectoire de circulation ; et un moyen de dégazéification disposé au centre de la trajectoire de circulation, et qui amène l'eau à s'écouler à travers celui-ci, et qui retire l'oxygène dissout dans l'eau. Ledit dispositif de commande est apte à maintenir de façon appropriée la concentration d'oxygène dissout dans l'eau, et est extrêmement approprié pour des dispositifs d'alimentation pour des organismes en haute mer.
