HOLLOW FIBER MEMBRANE MODULE

摘要

This invention provides a hollow fiber membrane module which can reduce p ressure loss in discharging water within a module and can reduce operating p ower. A hollow fiber membrane bundle comprising a plurality of numbers of ho llow fiber membranes are disposed within a cylindrical case having in its si de face an opening part for the inflow/outflow of water, and the end of the hollow fiber membrane bundle is fixed by bonding at a position which is loca ted in the axial direction of the cylindrical case at an outer position than the position of the opening part for the inflow/outflow of water on the sid e face of the cylindrical case. The hollow fiber membrane module is characte rized in that a distribution cylinder provided with distribution holes is pr ovided inward with respect to the opening part for the inflow/outflow of wat er on the side face of the cylindrical case and so as to surround the outer periphery of the hollow fiber membrane bundle, and grooves and/or corrugated protrusions are provided on the inner face of the distribution cylinder so as to be in communication with each other among the distribution holes.
