ABSTRACT:
Hollow fiber permeator units which are individually capable of producing 250,000 gallons per day of processed water and which can be economically made are disclosed. An elongate, ordered bundle of selectively permeable hollow fiber lengths passing through a central tubesheet is formed around a perforated feed tube containing a coaxial permeate conduit which is connected to permeate collecting bores in the tubesheet. The resulting assembly is enclosed in a filament-wound casing interrupted only by the tube portions extending from its ends.
