摘要： This invention provides a hollow fiber membrane module which can reduce pressure loss in discharging water within a module and can reduce operating power. A hollow fiber membrane bundle is disposed within a cylindrical case having in its side face an opening part for the inflow/outflow of water, and the end of the hollow fiber membrane bundle is bonded at an axially outer position with respect to the opening for the inflow/outflow of water. A distribution holes is provided axially inward of the opening for the inflow/outflow of water 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.

摘要： This invention provides a hollow fiber membrane module which can reduce pressure loss in discharging water within a module and can reduce operating power. A hollow fiber membrane bundle comprising a plurality of numbers of hollow fiber membranes are disposed within a cylindrical case having in its side 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 located 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 side face of the cylindrical case. The hollow fiber membrane module is characterized in that a distribution cylinder provided with distribution holes is provided inward with respect to the opening part for the inflow/outflow of water 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.
