A filtration apparatus (2) includes a pressurized cylindrical pressure vessel (4) having a longitudinal axis (X) and a shaft (8) having a longitudinal axis (Y) extending parallel to the longitudinal axis (X). A plurality of rotatable membrane filter discs (6) are arranged along the shaft (8). The membrane filter discs (6) are spaced-apart from each other, attached to the shaft (8) and oriented transverse to the longitudinal axis (Y) of the shaft (8). An interior (10) of the membrane filter discs (6) are in fluid communication with a permeate discharge channel (12) extending parallel to the longitudinal axis (X) of the pressure vessel (4). The pressure vessel (4) has a cylindrical inner geometry without any significant obstruction elements. The longitudinal axis (X) of the pressure vessel (4) is laterally offset from the longitudinal axis (Y) of the shaft (8) and/or the membrane filter discs (6) are oval-shaped.
