Summary:PURPOSE:To simply, stably and fully filter condensed water at high temp. over a long period of time while applying external pressure by filtering condensed water by a hydrophilic hollow fiber membrane module wherein an ethylene/vinyl alcohol copolymer is held on the surfaces of the pores of hollow fiber membranes made of a polysulfone resin. CONSTITUTION:Condensed water is fully filtered by a hydrophilic hollow fiber membrane module wherein an ethylene/vinyl alcohol copolymer is held on the surfaces of the pores of hollow fiber membranes made of a polysulfone resin while external pressure is applied to the condensed water. As a result, since the membranes are not buckled by high temp. and high pressure condensed water or the pores in the surface layers of the membranes are not collapsed, the condensed water can be stably filtered over a long period of time with high water permeability.
