Abstract: Fluid treatment arrangements and elements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. Two or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements. Posts may be located in some of the spaces and may be bonded to the adjacent fluid treatment elements. Bands may encircle some of the spaces to block radial fluid flow into or out of the spaces.

Abstract: Fluid treatment arrangements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. For some embodiments, the ribbon may comprise a composite having first and second layers. At least two and as many as many as fifty or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements. Many, most, or substantially all of the spaces may be substantially free of structure. A fluid treatment arrangement may be contained in a housing to form a fluid treatment assembly. The housing may include an inlet port and an outlet port and may define a fluid flow path between the inlet port and the outlet port. The fluid treatment arrangement may be positioned in the housing across the fluid flow path.

Abstract: Fluid treatment arrangements having at least first and second radially displaced sets (12,13) of fluid treatment elements and methods for making and using them are disclosed: A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element of either set. At least two and as many as fifty or more fluid treatment elements (14?, 14?) may be positioned along a hollow core assembly (11) in each set. Fluid may be directed to or from the interior of the core assembly through a fluid treatment element of the first set and a fluid treatment element of the second set. In each fluid treatment element, fluid flows generally edgewise through the permeable fluid treatment medium.

Abstract: Fluid treatment arrangements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. The disk-shaped body may include opposite end surfaces, an inner rim, and an outer rim. Up to one hundred or more fluid treatment elements may be positioned along a core assembly, and a surround may be positioned around the fluid treatment elements. The fluid treatment elements may be sealed to the core assembly with the inner rims covering openings in the core assembly, or the fluid treatment elements may be sealed to the surround with the outer rims covering openings in the surround. A fluid treatment arrangement may be contained in a housing to form a fluid treatment assembly. The housing may include an inlet port and an outlet port and may define a fluid flow path between the inlet port and the outlet port.

Abstract: Fluid treatment arrangements and elements and methods for making and using fluid treatment arrangements and elements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. The disk-shaped body may have first and second opposite end surfaces, e.g., an inflow surface and an outflow surface, and an outer rim. One or both of the end surfaces may be an uneven surface. At least two and as many as many as fifty or more fluid treatment elements may be positioned along a hollow core assembly. Fluid may be directed to or from the interior of the core assembly through each fluid treatment element. In each fluid treatment element, fluid flows from the inflow surface to the outflow surface generally edgewise through the permeable fluid treatment medium.
