<p><P>PROBLEM TO BE SOLVED: To provide a method for stably operating a film module for a long period by efficiently preventing clogging of a film when the film module for performing film filtration treatment of raw water is operated. <P>SOLUTION: The method for operating the film module performs operations while measuring zeta potential of the film, and performs the operations while controlling the film at a negative charge state based on a zeta potential measured value of the film for the method for operating the film module to be used for film filtration. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
