The apparatus comprises a cylindrical drum (20) that is supported on a rotatable shaft (21) having a centre axis (X-X), a number of filter plates (25) being attached to the drum (20), said filter plates (25) forming a filter surface (20A) on the drum (20), a scraper blade (31) for scraping a cake (60) from the filter surface (20A), an angular position sensor (70) for measuring the angular (φ) position of the drum (20). The filter apparatus (10) comprises further an actuator (30) for continuously adjusting the distance (D1) of a tip of the scraper blade (31) from the filter surface (20A) based on the predetermined topology of the filter surface (20A) at each angular (φ) position of the drum (20). |
