<P>PROBLEM TO BE SOLVED: To provide a porous membrane treatment apparatus which can simplify work to prevent a chemical from contacting with a porous membrane upon the stop of chemical treatment. <P>SOLUTION: A hollow fiber membrane treatment apparatus for use in a chemical treatment process of the porous membrane or a porous membrane precursor includes: a treatment tank 10 in which the chemical B is poured; a first guide means 12a which is set outside the treatment tank 10, and turns the conveyance direction of the porous membrane (hollow fiber membrane A) or the porous membrane precursor so that the porous membrane or the porous membrane precursor travels to be immersed in the chemical B; a second guide means 12b which turns the conveyance direction of the porous membrane or the porous membrane precursor traveling in the chemical B so that the porous membrane or the porous membrane precursor travels to be floated to a liquid surface; and a support member 13 which supports the first guide means 12a and the second guide means 12b, respectively, and can move up and down. <P>COPYRIGHT: (C)2013,JPO&INPIT |
