A cleaning system for removing solids from a liquid, the cleaning system comprising:

• at least two cleaning apparatuses, each cleaning apparatus comprising:
• an essentially horizontally arranged hollow cylindrical filter body separating a crude space from a clean space, the filter body surrounding the crude space and the clean space surrounding the filter body, the clean space acted upon by a pressure during a filtration operation;
• an inlet fluidly connected to the crude space;
• an outlet fluidly connected to the clean space;
• a backwashing device for cleaning solids from the filter body;
• a discharge mechanism for removing the cleaned solids from the crude space, the discharge mechanism including a screw conveyor for transporting the cleaned solids to a discharge opening;
• and
• a discharge valve for controlling the discharge opening;
• wherein the at least two cleaning apparatuses are connected in parallel to a fluid circuit that for conveying the liquid, the cleaning system further comprising an inlet valve connected to the inlet of at least one of the at least two cleaning apparatus, the inlet valve operable to separate the inlet from the fluid circuit.
