1. A filter device for separating a liquid mixture,
wherein the filter device (1) comprises a vessel (2) which is configured to contain at least one first filter element (14),
wherein the vessel (2) comprises an entry port (4) for introducing the liquid mixture into the first filter element (14),
wherein the vessel (2) further comprises a flat vessel base surface (6) configured to allow the vessel (2) to stably stand on a horizontal flat ground surface when the vessel base surface (6) is parallel to and level with the horizontal flat ground surface,
wherein the vessel (2) further comprises a vessel mantle surface (7) extending from a periphery of the vessel base surface (6) in a direction opposite to the vessel base surface (6),
wherein the filter device (1) comprises at least one housing (3, 3a, 3b) which is configured to contain at least one second filter element,
wherein the housing (3, 3a, 3b) comprises a flat housing base surface (11) configured to allow the housing to stably stand on a horizontal flat ground surface when the housing base surface (11) is parallel to and level with the horizontal flat ground surface,
wherein the housing (3, 3a, 3b) further comprises a housing mantle surface (12) extending from a periphery of the housing base surface (11) in a direction opposite to the housing base surface (11),
wherein the vessel mantle surface (7) comprises a re-entrant section (15) forming a recess configured to accommodate the housing (3, 3a, 3b),
wherein a mating side of the housing mantle surface (12) is configured to fit into the recess formed by the re-entrant section (15),
wherein the re-entrant section (15) and the mating side are provided with connection means (16) to fluidly connect an outlet of the first filter element (14) with an inlet of the second filter element in a detachable way when the mating side of the housing mantle surface (12) is fitted into the recess formed by the re-entrant section (15), and
wherein the re-entrant section (15) is extending from the vessel base surface (6), and that the vessel base surface (6) and the housing base surface (11) are parallel and level in the same plane when the mating side of the housing mantle surface (12) is fitted into the recess formed by the re-entrant section (15) such that the outlet of the first filter element (14) is fluidly connected with the inlet of the second filter element.
