Modular microporous filter assemblies
First Claim
1. A replaceable elongate and symmetrical filter cartridge comprising:
- A. An elongate filter medium comprising microporous hollow fibers adapted to be confined within an outer casing and terminating in opposed ends, said medium being adapted to be in fluid communication with at least first and second headers;
B. each of said opposed ends including a corresponding first and second end caps;
C. said end caps binding said filter medium at each opposed end and being adapted to releasably mechanically supported so as to maintain said opposed ends of said filter medium a predetermined distance apart;
D. said cartridge further comprising at least one connecting sleeve, axially slideable relative to said end caps and sealably engageable with said outer casing and said first and second headers.

Abstract
An improved microporous, modular filter structure assembled from replaceable filter cartridges (25) housed within a filter cartridge assemby (10) connected at opposed ends by means of symmetrical headers (41). The headers include a tube within a tube structure whereby they are adapted to conduct first and second fluids independently to both adjacent, like interconnected headers and into and out of filter cartridges (25) to which each header (41) is connected at both ends of each cartridge. Manifolds (100, 101) include a similar tube within a tube structure which allows them to be connected to the ends of rows of interconnected headers (41) whereby a modular filter bank can be constructed of indefinite dimension and capacity. A valve assembly (63) can be installed in each header (41) whereby the passage of one of the two fluids conductable from the filter cartridge assembly (10) to the header (41) can be isolated from the header ducts so that contamination of the output from adjacent headers can be selectively prevented.
