摘要： A dual bag filter is provided where a replaceable filter element resides in and is sealed to a filter housing. The filter element has a mounting ring, an inner bag, and an outer bag. The inner bag is sized such that it has more surface area than the outer bag and is constrained by the outer bag. The inner bag is formed from a filter medium of different densities such that when the inner bag is crumpled, fluid flow is not restricted.

摘要： Fluid treatment assemblies and elements may include a plurality of axially extending pleats and may be used to treat fluids, including gases, liquids, or mixtures of gases, and/or solids, in a crossflow mode of operation. For example, some fluid treatment assemblies and elements may be used to remove one or more substances from the fluid and may then function as separators, including filters and concentrators. Other fluid treatment assemblies and elements may be used to transfer substances between two fluid streams and may then function as mass transfer devices.

摘要： A papermakers' screen basket for pressure screening of papermaking stock or for pressure filtering is formed with a support core formed with honeycomb like cells that extend radially in the direction of flow through the screen basket, and a thin covering having screening openings therethrough is supported on the inlet surface of the honeycomb cell core. The core is formed by rolling a flat section of core into the shape of a cylinder and welding the abutting ends to form a complete cylinder and then attaching a perforated or a mesh sheet-like metal covering against the core inlet surface, in which the thin sheet metal covering defines small openings, such as slots or apertures, leading into the honeycomb core, and is welded in place.

摘要： An electrically conducting filter medium (20) is cleaned in situ by applying, at intervals, a brief voltage pulse between the medium (20) and a counter electrode (18) so the process liquid undergoes electrolysis. The cleaning process is significantly improved by occasionally applying a voltage of reverse polarity. For example a 5 second cleaning pulse making the filter medium (20) cathodic might be applied every quarter of an hour, and a reverse polarity pulse of similar duration applied every two hours. This process can significantly increase permeation rates.

摘要： The self-cleaning filter particularly for high-viscosity pasty fluids has a fixed body (2) having a substantially cylindrical elongated chamber (5) in which a filtration drum (9) is supported and defines a central region (10), at one end of which there is an inlet (14) for the fluid to be filtered, and an outer annular region (11), at the other end of which there is a duct (20) for the removal of the filtered fluid; a shaft (23) is axially supported and rotationally actuated in the chamber (5) and has a helical crest (25) the profile whereof is suitable for grazing the inner surface of the drum (9) to remove therefrom the impurities which are present and is suitable for pushing the fluid toward an impurity discharge duct (21) arranged at the other end of the chamber (5), the constant cleaning of the drum (9) being suitable for keeping constant the pressure drop on the filter.
