Abstract
Des aspects de l'invention concernent un appareil servant à séparer un second fluide ou une matière particulaire d'un fluide hôte. L'appareil comprend une chambre d'écoulement dotée d'au moins une entrée et d'au moins une sortie. Un circuit de pilotage est configuré pour fournir un signal de pilotage à un circuit de filtre configuré pour recevoir le signal de pilotage et fournir un signal de pilotage traduit. Un transducteur à ultrasons est disposé de manière coopérative avec la chambre d'écoulement, et le transducteur comporte au moins un élément piézoélectrique configuré pour être piloté par le signal de pilotage de courant en vue de créer une onde stationnaire acoustique dans la chambre d'écoulement. Au moins un réflecteur fait face au transducteur à ultrasons en vue de réfléchir l'énergie acoustique.
