A filter with filter chambers disposed in an annular zone on a rotatable common disc has a multitude of separate flow passages, each flow passage containing within its flow stream at least one filter chamber on the common rotatable disc, and each identical flow passage is rotated around the axis of rotation of this common rotatable disc, thus multiplying the flow capacity of a rotatable disc filter by using the same disc to filter multiple streams. The rotatable common filter disc is disposed within a slot formed by body blocks and spacer blocks and rotates around a hub, the spacer blocks and hub controlling slot width such that rotatable metal to metal seals form between the disc and the body blocks in contact with a surface of the disc, forming leak free seals. The rotation of the rotatable common disc causes filter chambers, sealed within the slot, to change filter chambers as material accumulates within the filter chambers. An extension of the body block in contact with the rotatable disc on the surface without filter chambers provides further support, more temperature uniformity, and prevents fluid dripage. The filter improvement with multiple flow passages provides for higher flow through any specific rotatable filter disc size.
