Filtration system for filtering a liquid, for examples swimming water, comprising a drum filter (2) provided with a primary inlet (4) and a primary outlet (6) in a housing (8), and a rotatable drum screen (10) arranged in the housing (8).A back flush element (12) is arranged on one side of the drum filter (2) for back flushing filtered particles from the drum screen (10), and a gutter element (14) is arranged on an opposite side of the drum screen (10) for collecting the filtered particles, wherein the gutter element (14) is connected to a secondary outlet (16) in the housing (2). The filtration system (1) is furthermore provided with a buffer reservoir (18) comprising a reservoir inlet (20) which is connected to the secondary outlet (16) so as to be closable. The filtration system (1) furthermore comprises compression means (34) for controlling a gas pressure (Pt) in the housing (8) of the drum filter (2) and a gas pressure (Pr) in the buffer reservoir (18). |
