Abstract

PURPOSE: To maintain filter resistance low for a long time and to provide a maintenance-free membrane separation equipment.
CONSTITUTION: The objective equipment consists of flat membrane modules 3 each of which is a filter medium consisting of a spacer 4 and a UF or MF membrane 5 (a planar separation membrane), a vessel 1 which is equipped with one or more flat membrane modules 3 and receives suspension liquid, and diffusing parts 9 of a diffuser arranged at the lower part of the flat membrane module 3 or at the lower side part of the filter medium. When the quantity of diffused air per hour from the diffuser is intermittently set large by a blower 11, a blower 13 and a valve 12, the movement of the suspension liquid is generated by gas 10, thus capable of maintaining the cleanness of the membrane surface.
