PCT No. PCT/SE97/01570 Sec. 371 Date Jun. 14, 1999 Sec. 102(e) Date Jun. 14, 1999 PCT Filed Sep. 18, 1997 PCT Pub. No. WO98/11972 PCT Pub. Date Mar. 26, 1998A filter sector for a rotating filter disc has filtrate conduits for filtrate resulting from filtration which is discharged at the more narrow end of the filter sector. The filtrate conduits are outwardly defined by a filtrating layer permeable to the filtrate. The filter sector has at least one element provided with a profiling forming the filtrate conduit. The profiled element itself forms the filtrating layer because the profiled element has a perforation permeable to the filtrate.
