Abstract

A filtering apparatus (1) for separating liquid from a slurry, comprising a first filtering means (10) comprising:- a receptacle (100) for holding slurry comprising an inlet (101) for slurry and an outlet (102) for de-liquefied slurry and;- at least one hollow cylinder (200) rotatable arranged in the receptacle (100) and comprising a liquid permeable wall portion (300) for allowing liquid of a slurry in the receptacle (100) to enter into the hollow cylinder (200) and;a second filtering means (20) comprising:- a liquid permeable planar filter (300) having a first face (301) arranged to receive deliquefied slurry from the receptacle (100) and configured to allow liquid of the deliquefied slurry to pass through the liquid permeable planar filter (300);- an elongated scraper (400) extending along at least a portion of the first face (301) of the planar filter (300) and rotatable arranged to move de-liquefied slurry along the first face (301) of the planar filter (300).
