Abstract
Disclosed is a hollow-fiber filter module having a novel structure in which a large number of hollow fibers for filtration use are disposed in a rectilinear fashion, two exit planes are defined by the opposite open ends of the hollow fibers, a filtrate collection chamber is formed over one of the exit planes, and one or more filtrate conduits are provided in order to conduct the filtrate collected in the filtrate collection chamber to the other exit plane. The hollow-fiber filter module permits the efficient utilization of a hollow-fiber filter membrane and, therefore, can reduce the space occupied by the module. Moreover, a plurality of such hollow-fiber filter modules can be connected in series and used in the form of a hollow-fiber filter module assembly having a length of several meters.
