ABSTRACT:
A rotating disc filter consists of disc sectors of preferably rustfree or acidproof steel about a filter shaft (9). Saddles (12) of a folded plate (1) form sector deck and support for filter cloth (4), and the troughs (13) of the folded plate together with the filter cloth abutting the saddles (12) form internal filtrate channels (11) extending from the outer periphery of the sector towards the filter shaft (9). Such a construction renders it possible to obtain sectors combining the requirements of large open filter cloth area, small internal volume affording for the filter operation an advantageously great ratio between filter surface and internal filtrate volume, high stability against lateral forces, and simple manufacture.
