Abstract

PURPOSE: To obtain highly purified water in an economical system by introducing raw water into the external part of a bundle comprising hollow yarn membranes not passing a substance with a particle size of 80Å or more and having a pure water permeating speed in a specific range and wholly filtered therethrough under external pressure.
CONSTITUTION: By an external pressure type whole filtering system wherein raw water is supplied under pressure to the external surface side of a bundle comprising hollow yarn membranes not passing a substance with a particle size of 80Å or more and having a pure water permeating speed of 2.5×102m2/m2. hr.kg/cm2 or more and a filtrate is taken out into the internal surface side thereof, purified water is prepared. In carrying out the external pressure whole filtering system, filtering pressure applied to raw water is 0.1kg/cm2 or more, pref., 0.5kg/cm2 or more. In filtering, plural numbers of hollow yarn membranes are sealed by a sealant and the hollow yarn bundle having an open end provided to at least one end thereof is fabricated. As the blank mateial of the hollow yarn membrane, a polyacrylonitrile type, a cellulose type or a polyamide type can be used.
