Abstract:
1. A fluid treatment arrangement comprising a plurality of fluid treatment modules, wherein each module includes a permeable fluid treatment medium having a feed surface and an opposite permeate surface, a feed region extending along the feed surface of the fluid treatment medium, and a permeate region extending along the permeate surface of the fluid treatment medium, wherein each module further includes a feed end fluidly coupled to the feed region and sealed from the permeate region and a retentate end fluidly coupled to the feed region and sealed from the permeate region, and wherein the fluid treatment modules are fluidly coupled to one another, the retentate end of one fluid treatment module fluidly communicating with the feed end of a succeeding fluid treatment module, a core assembly which extends through the plurality of fluid treatment modules, the core assembly having one or more permeate passages that fluidly communicate with the permeate regions of the fluid treatment modules, and one or more control mechanisms, a control mechanism being fluidly coupled to the permeate region of at least one fluid treatment module to control a flow parameter in the permeate region of the module.
