The flexibility of the submerged hollow fibers under bubbling conditions can be promoted by having the fibers held loosely rather than tightly. Chang and Fane [101] indicated that there are significant differences in suction pressure profiles for filtration with tightly and loosely fixed fiber modules. Similarly, Wicaksana et al. [102] showed that the rate... [Pg.284]

Capital Costs The capital costs have dropped for aU membrane systems. However, there is evidence that submerged hoUow-fiber modules have marginally lower costs, particularly for larger plants, due to the absence of pressure vessels, simpler plumbing and simplicity of the hollow-fiber bundle. [Pg.245]

Repiacement and Repair Influences maintenance and labor costs. The most convenient modules to repair use hollow fibers rather than tubes or flat plates. Both contained and submerged hollow fibers can be monitored, and the individual damaged fiber eventually identified and plugged. The procedure tends to be labor intensive in either system. [Pg.246]

Hollow fibers are generally used for submerged applications, although flat sheets, and more recently, spiral wound modules have come into use in submerged systems. In general, pressurized and submerged systems compare favorably, with the submerged... [Pg.337]
