Abstract

Hollow-fiber membranes for reverse osmosis desalination are typically of the dense wall type and exhibit water flux rates in the range of 0.1–1 gallons/square foot-day (gfd) [1,2]. These low flux rates are overcome by making the fibers extremely small (50 microns) in order to develop a relatively compact desalination system. Still, the need exists for hollow-fiber membranes with flux rates greater than those of dense wall fibers. Such membranes could be used to develop highly compact modules and further improve the economics of reverse osmosis desalination.
