A panel sector, for a disc filter for separation of liquids from a
suspension, includes front and back filter panel assemblies, a sector
assembly for mounting the front and back filter panel assemblies, and a
top cap for retaining the filter panel assemblies within the sector
assembly. Each of the filter panel assemblies includes a frame and a
filter material clamped by the frame. The sector assembly includes an
outer end plate, an inner core mounting plate subassembly for mounting
the panel sector to the disc filter core, first and second side channel
subassemblies, at least one structural member extending radially between
the core mounting plate subassembly and the outer end plate, and at least
one support member extending laterally between the first and second side
channel subassemblies. The core mounting plate subassembly and each of
the side channel subassemblies have front and back channels for receiving
portions of the frame. The top cap first and second end portions are
removably mountable to the outer end plate of a one of the sector
assemblies and the outer end plate of an adjacent sector assembly,
respectively.
