PROBLEM TO BE SOLVED: To provide an apparatus for concentrating slurry which can be operated continuously since a moving medium can be actuated under low pressure and which is suitable for obtaining low-concentration slurry and to provide a method for concentrating slurry. SOLUTION: The apparatus for concentrating slurry in which one or more filtration cylinders 2 each consisting of a filter medium are arranged and the slurry is fed forcibly to the inside of the filtration cylinder 2 to perform filtration/concentration, includes: a guide rod 11 fixed/arranged along the axial center of the filtration cylinder 2; a piston 12 which is inserted into the filtration cylinders to be slid on the guide rod 11, has the outer peripheral surface of the diameter smaller than the inside diameter of the filtration cylinder 2 and is reciprocated from one end of the filtration cylinder 2 to the other end thereof; and a slurry supply unit for forcibly feeding the slurry to the inside of the filtration cylinder 2. Both ends of the filtration cylinder 2 are connected respectively to side pipes 3a, 3b for performing introduction and discharge of the slurry and each of the side pipes 3a, 3b is connected to the slurry supply unit while interposing a changeover valve between them.
