Abstract

L'invention concerne un procédé d'aspiration régulée de matières en suspension dans l'air ou dans un liquide. Ce procédé est caractérisé par le fait qu'un dispositif de levage reçoit une commande de réglage en hauteur d'une tuyère d'aspiration sous forme de signaux émis par un palpeur de débit ou de concentration en matières solides, préréglé de façon à délivrer un signal de commande au dispositif de levage pour soulever ou abaisser la tuyère et rétablir de ce fait le débit ou la valeur de la concentration en matières solides dans la conduite tubulaire, lorsqu'ils dépassent une valeur prédéterminée, le circuit électrique de commande auquel le palpeur de débit ou de concentration en matières solides est connecté, envoyant le signal de commande à une soupape de commande ou au moteur d'entraînement de la pompe, pour accroître ou diminuer la quantité débitée. L'invention s'applique aux bassins de décantation de boues.
