PURPOSE:To definitely wash the end parts of the filter material in a fluid separation apparatus only in a necessary range, by supplying a washing liquid to the end part of the fluid separation apparatus having a receiving tank connected to the end part thereof by centrifugal force generated by rotating a turntable while discharging the used washing liquid to the receiving tank. CONSTITUTION:A fluid separation apparatus 1 wherein equal length hollow filter material groups 2 are bundled to be received in a cylindrical case 3 provided with nozzles 4, 4' is horizontally fixed on a turntable 7 through an attached jig 8 and connected to a receiving tank 11 through a check valve 12 by inlaying injection molded jigs 5 to both end parts thereof. In this state, the turntable 7 is rotated by a rotary shaft 6 and the washing liquid A in a pot 9 provided in coaxial relation to the rotary shaft 6 is supplied into the injection molded jigs 5 through liquid feed tubes 10 by the generated centrifugal force to wash the end parts of the filter material 2 in a state immersed under a predetermined liquid level 13. After washing for a predetermined time, the rotation speed of the turntable 7 is raised to increase the centrifugal force and the washing liquid is discharged to and recovered by the receiving tank 11 against the closing force of the check valve 12.
