In a rotating disc filter for dewatering a suspension comprising filter discs (3) divided into a plurality of disc sectors (4), the discharge of filtrate from each disc sector takes place through an axial filtrate channel (7). Each filtrate channel is at the side wall of the filter connected to a fall pipe (8) which rotates with the channel and extends in radial direction relative to the filter shaft (6). Preferably each of said filtrate channels is at said side wall provided with a pre-filtrate outlet (10).
