  • Integrated use of deaeration methods to reduce bubbles and liquid waste
    Patent number: 6648943
    Abstract: A method is taught for removing bubbles from a coating solution prior to a coating operation. The method comprises debubbling the coating solution in a tank open to atmosphere to remove bubbles having a diameter in the range of from about 200 to 300 &mgr;m and greater therefrom; flowing the coating solution from the tank to a bubble elimination tube; debubbling the coating solution in the bubble elimination tube to remove bubbles from the coating solution having a diameter greater than about 200 &mgr;m, the bubble elimination tube preferably including at least one ultrasonic horn; flowing the coating solution from the bubble elimination tube through an end cap round ultrasonic bubble eliminator, the end cap round ultrasonic bubble eliminator removing remaining bubbles in the coating solution having a diameter greater than about 30 &mgr;m; and delivering the coating solution from the end cap round ultrasonic bubble eliminator to the downstream coating operation.
