Abstract: A method operates a filter device for polymer melt to be filtered. The filter device incorporates at least one first large-area filter in a first filter chamber and a second large-area filter in a second filter chamber; a first valve in a first inlet to the first filter chamber and a second valve in a second inlet to the second filter chamber to control the polymer melt to be filtered; a first drain valve in a first drain for the filtered polymer melt from the first filter chamber and a second drain valve in a second drain for the filtered polymer melt from the second filter chamber. The polymer melt to be filtered is conveyed under pressure through the filter device. The first inlet and the second inlet are connected to a common inlet and the first drain and the second drain are connected to a common drain. Polymer melt to be filtered is simultaneously fed to the first and second large-area filters in the filter direction. Parallel filtering is continuously performed via the first and second large-area filters. A backflushing operation for filtering via only one large-area filter is started when the large-area filter reaches a predefined degree of contamination at which the first large-area filter is cleaned.

Abstract: A filter device has a filter housing (14) with a housing pot (12), which accommodates a replaceable filter element (16) and is closed by a removable lid part (32). The element material (20) of the filter element (16) separates an unfiltrate chamber (22) from a filtrate chamber (18, 43). A measurement sensing device (108) senses pressure values from at least one of the chambers (18, 22, 43), is disposed on a lid inner side (45) of the lid part (32), is at least partially guided in the lid part, and projects into the filter housing (14). At least parts of a measurement value evaluator (78) are connected to the measurement sensing device (108) and are disposed on the opposite lid outer side (42) facing the environment.

Abstract: A movable seal for interfacing between a first surface and a second surface includes a floating portion attached to a non-floating portion by a flexible coupling portion, wherein the non-floating portion is coupled to the first surface by nesting in a groove on the first surface, and wherein the non-floating portion forms a seal between the first and second surfaces when the first surface moves relative to the second surface in a first direction, and wherein the non-floating portion does not form a seal between the first and second surfaces when the first surface moves relative to the second surface in a second opposite direction.

Abstract: A dip tank and recycling system for applying antimicrobial solution to food items, including a dip tank having a bottom and sides, and holding a liquid antimicrobial solution. A conveyor to convey food items through the tank passes through the liquid antimicrobial solution held in the tank such that food items conveyed on the conveyor are dipped in the liquid antimicrobial solution. At least two discharge nozzles spray fresh antimicrobial solution into the tank. The discharge nozzles are located in the sides of the tank, and are positioned above the level of the conveyor but below an expected top level of the liquid antimicrobial solution contained within the tank such that food items conveyed on the conveyor are agitated by the force of the spray from the discharge nozzles. The spray from the discharge nozzles causes unstacking of items on the conveyor, producing an even application of the antimicrobial solution.

Abstract: There is provided a filter for a diaphragm valve. The filter attaches to a diaphragm of the valve and filters fluid entering a control chamber in the valve. The filter includes internal structure that increases the path from where fluid enters the filter through a mesh of holes to a single exit flow path leading to the control chamber. This increased path reduces the potential for debris in the flow to clog the exit flow path from the filter.

Abstract: A method including the steps of providing fluid through an inlet into a vessel at atmospheric pressure. The method further includes passing the fluid through a filtration unit utilizing a downstream pump, the filtration unit creating a flux of less than or equal to about 0.05 gallons per minute per square foot (GPM/ft2), and moving the fluid processed by the filtration unit through an outlet of the vessel.
