Abstract:
A hollow fiber membrane module comprising:a hollow fiber membrane bundle including a plurality of layers of cheese-wound permselective hollow fiber membranes, each of said hollow fiber membranes being formed of thermoplastic resin and having rigidity; a sealed part formed of thermoplastic resin in at least one terminal part of said hollow fiber membrane bundle; a module casing enclosing said hollow fiber membrane bundle, said module casing having an inflow port at a first end, a discharge port at a second end opposite said first end, and an outflow port between said inflow port and said discharge port; a hydrophobic porous mass embedded in a first end of said hollow fiber membrane bundle so as to extend in a longitudinal direction of said hollow fiber membrane bundle; and a retaining part embedded in a second end of said hollow fiber membrane bundle opposite said first end so as to extend in a longitudinal direction of said hollow fiber membrane bundle; wherein said hollow fiber membrane module has a module diameter d and a module length L, said hollow fiber membrane module having a ratio d/L greater than 0.6, said hollow fiber membrane module comprising one of a deaeration module, a drier module, a pervaporation module, a bioreactor module, a gas separation module, an artificial dialysis module, and an artificial lung module.
