<P>PROBLEM TO BE SOLVED: To obtain a disk spacer of a filtration separation apparatus wherein the surface of the selected layer of a filtration element is never damaged even if it is used for a long time under high pressure and high temperature while maintaining the advantage of a spacer. <P>SOLUTION: The spacer (11) is accommodated inside the cylindrical housing of the filtration separation apparatus (10) for filtrating and separating a fluid medium (15) by reverse penetration and ultra filtration to guide the flow of the fluid medium (15). One filtration element (13) is interposed between a pair of the disk spacers (11), a number of opening parts (14) is formed around the center hall (12) of the spacer at an even interval in a circumference direction, a number of protrusion parts (29) erected on the surface on the surfaces (130 and 131) of at least one side of the spacer (11) are formed at an even interval in a circumference direction such that the fluid medium (15) flows in from around the spacer (11) and flows out to the opening parts (14), and a surface (290) parallel with surfaces (118 and 119) is provided on the protrusion part (29). <P>COPYRIGHT: (C)2007,JPO&INPIT |
