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.
