Abstract
A rotating disc filter has a plurality of discs, each made of a plurality of sectors removably mounted on support structures which are fixed on a rotating hollow shaft into core drainage channels of which, the sectors drain. The drainage and support structure has flow channels designed to rapidly drain filtrate and to permit filtrate split between clear and fiber bearing fractions. Rapid drainage is made possible by a novel method and device for controlling fluid transit volume within the sectors.
