Abstract

A manifold structure for connecting rows of cartridges (100) to adjacent like rows of cartridges (100). The manifold structure includes a first fluid passage (153, 183) adapted to pass either feed or filtrate through the body of the manifold structure, a second fluid passageway (169, 197) adapted to be coupled to a first passageway of a filter cartridge to provide fluid communication between the cartridge and the first passageway, a third fluid passageway (167, 199) adapted to be coupled to a second passageway of the filter cartridge to provide fluid communication between the cartridge and the first passageway; only one of the second fluid passageway or the third fluid passageway being enabled for fluid communication at any one time. This manifold structure allows construction of a filter installation comprising a plurality of rows of interconnected filter cartridges (100) whereby feed and filtrate flow can be made to run in parallel through connected rows of filter cartridges (100) using readily interchangeable manifold components. The manifolds also allow installation of blocking or wafer valves (241) for the purpose of either series connecting groups of parallel connected filter cartridges or for flow regulation.
