PURPOSE:To efficiently recover a liq. medium by filtration from a suspension and to obtain the concd. suspension by vibrating a platy body provided on the raw liq. side in opposition to a filtration surface in parallel with the filtration surface. CONSTITUTION:When a liq. contg. solid suspended matter is filtered and concentrated, a diaphragm 3 is provided on the raw liq. side in opposition to the filtration surface consisting of a filter cloth 2, etc., and in parallel with the filtration surface, and vibrated in parallel with the filtration surface. Consequently, the deposition of cake on the filtration surface is prevented, only the filtrate can be precisely recovered from the suspension for a long time, and filtration can be performed with high efficiency. Furthermore, the energy to be used is reduced, the damage of the device, the filter medium, etc., is reduced, and the filter has a long service life.
