Abstract
The utility of hollow fiber reverse osmosis membranes in renovation of secondary municipal effluent was investigated through construction, laboratory evaluation, and monitoring in field service of various hollow fiber modules. All units incorporated cellulose acetate hollow fibers, annealed for sodium chloride rejections of 80-95% at 250 psi external operating pressure. Product water capacities ranged from 50-300 gallons per day. Module designs considered included the single seal end, looped fiber bundle; double seal end, parallel bundle; radial flow parallel bundle; and a rolled, woven hollow fiber fabric. The typical flux-rejection characteristics of the basic fiber system (4 gfd-95%) were observed in waste water service, but steady-state flux, maintained only with regular detergent flushes, was usually less than 1 gfd, with an accompanying decline in selectivity. A notable exception was the woven hollow fiber fabric design, which showed improved retention of start-up characteristics and minimum effects of shell-side fouling during short-term field tests.
