SLUDGE CONCENTRATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a sludge concentration device where solid-liquid separation is performed by centrifugal force, thus the arrangement of an expensive suction pump and complicated suction piping used for solid-liquid separation using a membrane can be made needless. SOLUTION: A concentration tank 2 provided with a solid-liquid separation membrane 1 at the circumferential face is rotatably supported inside a casing 3, and further, a rotation driving means 4 of rotating the concentration tank 2 and filtering the concentrated sludge G fed to the concentration tank 2 by centrifugal force is provided.
